Term
Define Class A airspace.
Definition
Airspace from 18,000 feet MSL up to and including FL 600, including the airspace overlying the waters within 12 nautical miles of the coast of the 48 contiguous States and Alaska.

IFR rules required.

Visibility: N/A

Distance to clouds: N/A
Term
Define Class B airspace
Definition
From the surface to 10,000 feet MSL.

surrounds the nation's busiest airports in terms of IFR operations or passenger enplanements. The configuration of each Class B airspace area is individually tailored and consists of a surface area and two or more layers (resembling upside-down wedding cakes); designed to contain all published instrument procedures once an aircraft enters the airspace.

Visibility: 3 statute miles

Distance from clouds: Clear of clouds
Term
What is required in Class B airspace?
Definition
An ATC clearance is required for all aircraft to operate in Class B Airspace, and all aircraft that so cleared receive separation services within the airspace. The cloud clearance requirement for VFR operations is "clear of clouds".

Arriving or transiting aircraft must obtain an ATC clearance prior to entering Class B airspace on the appropriate frequency and relation to geographical fixes shown on local Class B aeronautical charts. Departing aircraft require a clearance to depart Class B airspace and should advise clearance delivery of their intended altitude and route of flight.

The aircraft must be equipped with an operable two-way radio capable of communicating with ATC on appropriate frequencies for that Class B airspace.

The aircraft must be equipped with an operable radar beacon transponder with automatic altitude reporting equipment.

Mode C Veil A mode C transponder with altitude reporting is required within 30 nautical miles of a Class B airport from the surface to 10,000 feet MSL.

An aircraft w/o a certified system installed may conduct operations within a Mode C veil provided the aircraft remains outside Class A, B, or C airspace; and below the altitude of the ceiling of a Class B (10,000 ft MSL) or Class C (4,000 ft MSL) airspace area designated for an airport or 10,000 feet MSL, whichever is lower.
Term
Define Class C airspace
Definition
From the surface to 4,000 feet MSL above the airport elevation.

Surrounds those airports that have an operational control tower, are serviced by a radar approach control, and have a certain number of IFR operations or passenger enplanements.

Visibility: 3 statute miles

Distance to clouds: 1000 feet above, 500 feet below, 2000 feet horizontal
Term
What are the characteristics of Class C airspace?
Definition
Each Class C airspace area is individually tailored. The airspace usually consists of a 5 NM radius core surface area that extends from the surface up to 4,000 feet above the airport elevation, and a 10 NM radius shelf area that extends no lower than 1,200 feet up to 4,000 feet above airport elevation.
Term
What is required in Class C airspace?
Definition
A two way radio and unless otherwise authorized by ATC an operable radar beacon transponder with automatic altitude reporting equipment is required.

Two way radio communication must be established with the ATC facility providing ATC services prior to entry and thereafter maintain those communications while in Class C airspace.

Pilots of arriving aircraft should contact the Class C airspace ATC facility on the publicized frequency and give their position, altitude, radar beacon code destination, and request Class C service.

Radio contact should be initiated far enough from the Class C airspace boundary to preclude entering Class C airspace before two way radio communications are established. If the controller responds to a radio call with, "aircraft call sign, standby" radio communications have been established and the pilot can enter the Class C airspace.
Term
What should you know about ATC instructions in Class C airspace?
Definition
If workload or traffic conditions prevent immediate provision of Class C services, the controller will inform the pilot to remain outside the Class C airspace until conditions permit the services to be provided.

It is important to understand that if the controller responds to the initial radio call without using the aircraft call, radio communications have not been established and the pilot may not enter the Class C airspace.
Term
Define Class D airspace
Definition
Airspace from the surface to 2,500 ft MSL above the airport elevation.

Visibility: 3 statute miles

Distance to clouds: 1000 feet above, 500 feet below, 2000 feet horizontal (same as class C).
Term
What is required in Class D airspace?
Definition
An operable two way radio is required.

Two way radio communication must be established with the ATC facility providing ATC services prior to entry and thereafter maintain those communications while in Class D airspace.

Pilots of arriving aircraft should contact the control tower on the publicized frequency and give their position, altitude, destination, and any request(s).

Radio contact should be initiated far enough from Class D airspace boundary to preclude entering the Class D airspace boundary to preclude entering Class D airspace before two way radio communications are established.

If the controller responds to a radio call with, "aircraft call sign, standby," radio communications have been established and the pilot can enter the Class D airspace. If workload or traffic conditions prevent immediate entry into Class D airspace, the controller will inform the pilot to remain outside the Class D airspace until conditions permit entry.
Term
Define Class E airspace.
Definition
Class E airspace is the controlled airspace not classified as Class A, B, C, or D airspace. Generally, ATC authorization is not needed.

1. Sectional and other charts depict
all Class E airspace below 14,500 feet
MSL.
2. Where charts don't depict a Class E
base, it begins at 14,500 feet MSL.
3. In most areas Class E airspace base is
1,200 feet AGL.
3. In other areas, Class E airspace is
either the surface or 700 ft AGL.
4. Some Class E airspace begins at a chart-depicted altitude in feet MSL or MSL instead of MGL.

Ceiling: Up to but not including 18,000 ft MSL (the lower limit of Class A airspace). All altitudes above FL 600.
At or above 10,000 feet MSL:
Visibility: 5 statute miles
Distance to clouds: 1,000 feet above, 1,000 feet below, 1 SM horizontal.

Less than 10,000 feet MSL:
Visibility: 3 statute miles
Distance to clouds: 1,000 feet above, 500 feet below, 2,000 feet horizontal (same as Class C, D and G below 10,000 feet MSL).
Term
What are the steps for good decision­-making?

aka Aeronautical Decision-Making (ADM)
Definition
1. Identifying personal attitudes
hazardous to safe flight.
2. Learning behavior modification
techniques.
3. Learning how to recognize and
cope with stress.
4. Developing risk assessment skills.
5. Using all resources.
6. Evaluating the effectiveness of
one’s ADM skills.
Term
What are the six steps of the formal risk management decision­making process?
Definition
1. Identify Hazards
2. Assess Risks
3. Analyze Controls
4. Make Control Decisions
5. Use Controls
6. Monitor Results
Term
What are the four fundamental principles of risk management?
Definition
1. Accept no unnecessary risk. Flying is not possible without risk, but unnecessary risk comes without a corresponding return.

2. Make risk decisions at the appropriate level. Risk decisions should be made by the person who can develop and implement risk controls.

3. Accept risk when benefits outweigh dangers (costs).

4. Integrate risk management into planning at all levels. Because risk is an unavoidable part of every flight, safety requires the use of appropriate and effective risk management not just in the preflight planning stage, but in all stages of the flight.
Term
How is SRM defined?
Definition
Single­ Pilot Resource Management (SRM) is:

1. The art and science of managing all the resources available to a single pilot (prior to and during flight) to ensure the successful outcome of the flight.
Term
What does SRM include?
Definition
SRM includes:
1. the concepts of Aerial Decision Making (ADM),
2. risk management (RM),
3. task management (TM),
4. automation management (AM),
5. controlled flight into terrain (CFIT) awareness,
6. situational awareness (SA).
Term
How does SRM help the pilot?
Definition
SRM training helps the pilot:
1. maintain situational awareness by
2. managing the automation and associated aircraft control and
3. navigation tasks.

This enables the pilot to:
1. accurately assess and manage risk and
2. make accurate and timely decisions.
Term
What are the two defining elements of ADM?
Definition
Hazard and risk.
Term
What is a Hazard as defined by ADM?
Definition
Hazard is a real or perceived condition, event, or circumstance that a pilot encounters.
Term
What does a pilot do when faced with a hazard as defined by ADM?
Definition
The pilot makes an assessment of that hazard based upon various factors. The pilot assigns a value to the potential impact of the hazard, which qualifies the pilot’s assessment of the hazard, that being the risk involved.
Term
How is risk defined according to ADM?
Definition
Risk is an assessment of the single or cumulative hazard facing a pilot.
Term
What is the antidote for an Anti-authority "Don't tell me" attitude?
Definition
Follow the rues. They are usually right.
Term
What are the five hazardous attitudes?
Definition
anti­authority, macho, impulsivity, resignation, invulnerability (AMIRI)
Term
How are hazardous thought neutralized?
Definition
By recognizing them.
Term
What should a pilot do after recognizing a thought as hazardous?
Definition
The pilot should label it as hazardous, then state the corresponding antidote.
Term
What is the antidote for Impulsivity, a "Do it quickly" attitude?
Definition
Not so fast. Think first.
Term
What is the antidote for Invulnerability, an "It won't happen to me" attitude?
Definition
It could happen to me.
Term
What is the antidote for a Macho "I can do it" attitude?
Definition
Taking chances is foolish.
Term
What is the antidote for Resignation, a "What's the use" attitude?
Definition
I'm not helpless. I can make a difference.
Term
What does the pilot need to do to fly safely?
Definition
Assess the degree of risk and determine the best course of action to mitigate the risk.
Term
One of the best ways single pilots can mitigate risk is to use the IMSAFE checklist to determine physical and mental readiness for flying. What does IMSAFE stand for?
Definition
1. Illness — Am I sick? Illness is an obvious pilot risk.
2. Medication — Am I taking any medicines that might affect my judgment or make me drowsy?
3. Stress — Am I under psychological pressure from the job? Do I have money, health, or family problems? Stress causes concentration and performance problems. While the regulations list medical conditions that require grounding, stress is not among them. The pilot should consider the effects of stress on performance.
4. Alcohol — Have I been drinking within 8 hours? Within 24 hours? As little as one ounce of liquor, one bottle of beer, or four ounces of wine can impair flying skills. Alcohol also renders a pilot more susceptible to disorientation and hypoxia.
5. Fatigue — Am I tired and not adequately rested? Fatigue continues to be one of the most insidious hazards to flight safety, as it may not be apparent to a pilot until serious errors are made.
6. Emotion — Am I emotionally upset?
Term
the risk mitigation and hazard perception PAVE preflight planning checklist stand for?
Definition
1. Pilot-­in­-command (PIC),
2. Aircraft,
3. enVironment, and
4. External pressures
are PAVE which form part of a pilot’s decision­making process.
Term
What must a pilot do once the risks of a flight are indentified?
Definition
He or she needs to decide whether the risk, or combination of risks, can be managed safely and successfully. If not, make the decision to cancel the flight. If the pilot decides to continue with the flight, he or she should develop strategies to mitigate the risks. One way a pilot can control the risks is to set personal minimums for items in each risk category.
Term
What are the P risk factors in a flight?
Definition
P = Pilot­in­Command (PIC): The pilot must ask, “Am I ready for this flight?” in terms of experience, recency, currency, physical, and emotional condition. The IMSAFE checklist provides the answers.
Term
What are the A limitation questions a pilot must ask before a flight?
Definition
A = Aircraft:
1. Is this the right aircraft for the flight?
2. Am I familiar with and current in this aircraft?
3. Can this aircraft carry the planned load?
Term
What are the V considerations a pilot must consider before a flight?
Definition
WEATHER
1. What is the current ceiling and visibility?
2. Consider the possibility that the weather may be different than forecast. 3. Are there any thunderstorms present or forecast?
4. If there are clouds, is there any icing, current or forecast? What is the temperature/dew point spread and the current temperature at altitude?

TERRAIN
Evaluation of terrain is another important component of analyzing the flight environment.

AIRSPACE
Check the airspace and any temporary flight restriction (TFRs).
Term
What are the E factors influencing a pilot and creating a sense of pressure to fly?
Definition
1. The desire to demonstrate pilot qualifications
2. The desire to impress someone (Probably the two most dangerous words in aviation are “Watch this!”)
3. The pilot’s general goal-­completion orientation
4. Emotional pressure associated with acknowledging that skill and experience levels may be lower than a pilot would like them to be. Pride can be a powerful external factor!
Term
How can external pressures be managed by the pilot so s/he does not ignore risk factors?
Definition
The use of personal standard operating procedures (SOPs) is one way to manage external pressures. The goal is to supply a release for the external pressures of a flight.
Term
What is the definition for airports?
Definition
Any area of land or water used or intended for landing or takeoff of aircraft, including special types of facilities such as seaplane bases, heliports, and facilities to accommodate tilt rotor aircraft.

An airport includes an area used or intended for airport buildings, facilities, as well as rights of way together with the buildings and facilities.
Term
What are the types of airports?
Definition
1. Towered
2. Non-towered

Subdivided into:

a. Civil Airports open to the general public
b. Military/Federal Government airports, i.e., airports operated by the military, NASA, or other agencies of the Federal Government.
c. Private Airports designated for private or restricted use only, not open to the general public
Term
What does a Towered Airport have?
Definition
A towered airport has an operating control tower. Air traffic control (ATC) is responsible for providing the safe, orderly, and expeditious flow of air traffic at airports where the type of operations and/or volume of traffic requires such a service.
Term
What does Non-towered Airport not have/require?
Definition
It does not have an operating control tower and two-­way radio communications are not required.
Term
How does a sUAS pilot obtain information from a Non-Towered Airport?
Definition
It is a good operating practice for pilots to monitor other aircraft on the specified frequency for the benefit of other traffic in the area. The key to monitoring traffic at an airport without an operating control tower is selection of the correct common frequency (CTAF).
Term
What is CTAF?
Definition
The acronym CTAF stands for Common Traffic Advisory Frequency. A CTAF is a frequency designated for the purpose of carrying out airport advisory practices while operating to or from an airport without an operating control tower. The CTAF may be a Universal Integrated Community (UNICOM), MULTICOM, FSS, or tower frequency and is identified in appropriate aeronautical publications.
Term
What is UNICOM?
Definition
UNICOM is a nongovernment air/ground radio communication station that may provide airport information at public use airports where there is no tower or FSS.
Term
What is the default radio frequency at Non-towered airports which do not have a frequency listed on an AIM?
Definition
Term
What are the required Non-tower Airport incoming entry procedures?
Definition
Non­towered airport traffic patterns are always entered at pattern altitude. How you enter the pattern depends upon the direction of arrival. The preferred method for entering from the downwind side of the pattern is to approach the pattern on a course 45 degrees to the downwind leg and join the pattern at midfield.
Term
What are the four common information sources that provide a sUAS pilot with data for, e.g., communication frequencies, services available, closed runways, or airport construction?
Definition
1. Aeronautical charts
2. Chart Supplement U.S. (formerly
Airport/Facility Directory)
3. Notices to Airmen (NOTAMs)
4. Automated Terminal Information Service (ATIS)
Term
By what distance should all skeletal structures be avoided?
Definition
At least 2,000 feet.
Term
Define Class G Airspace.
Definition
the portion of the airspace that has not been designated as Class A, B, C, D, or E. It is therefore uncontrolled airspace. Class G airspace extends from the surface to the base of the overlying Class E airspace. A remote pilot will not need ATC authorization to operate in Class G airspace.

At 1,200 feet or less by day:
Visibility: 1 statute mile
Distance from clouds: Clear of clouds

At 1,200 feet or less by night:
Visibility: 3 statute miles
Distance from clouds: 1,000 ft above, 500 feet below. 2,000 ft horizontal

At more than 1,200 feet by day:
Visibility: 1 statute mile
Distance from clouds: 1,000 ft above, 500 feet below. 2,000 ft horizontal

At more than 1,200 feet by night:
Visibility: 3 statute miles
Distance from clouds: 1,000 ft above, 500 feet below. 2,000 ft horizontal

At more than 1,200 feet above the surface and at or above 10,000 feet:
Visibility: 5 statute miles
Distance from clouds: 1,000 ft above, 1,000 feet below. 1 SM horizontal
Term
Define Special Use Airspace.
Definition
Special use airspace or special area of operation (SAO) is the designation for airspace in which certain activities must be confined, or where limitations may be imposed on aircraft operations that are not part of those activities. Special use airspace usually consists of:
1. Prohibited areas
2. Restricted areas
3. Warning areas
4. Military operation areas (MOAs)
5. Alert areas
6. Controlled firing areas (CFAs)

Certain special use airspace areas can create limitations on the mixed use of airspace. The special use airspace depicted on instrument charts includes: 1. the area name or number
2. effective altitude
3. time and weather conditions of
operation
4. the controlling agency
5. the chart panel location
Term
What are Prohibited Areas?
Definition
Prohibited areas contain airspace of defined dimensions within which the flight of aircraft is prohibited. Such areas are established for security or other reasons associated with the national welfare. These areas are published in the Federal Register and are depicted on aeronautical charts. The area is charted as a “P” followed by a number (e.g., P­40).
Term
What are Restricted Areas?
Definition
Restricted areas are areas where operations are hazardous to nonparticipating aircraft and contain airspace within which the flight of aircraft, while not wholly prohibited, is subject to restrictions. Activities within these areas must be confined because of their nature, or limitations may be imposed upon aircraft operations that are not a part of those activities, or both. Restricted areas denote the existence of unusual, often invisible, hazards to aircraft (e.g., artillery firing, aerial gunnery, or guided missiles). Penetration of restricted areas without authorization from the using or controlling agency may be extremely hazardous to the aircraft.

1. If the restricted area is not active and has been released to the FAA, the ATC facility allows the aircraft to operate in the restricted airspace without issuing specific clearance for it to do so.

2. If the restricted area is active and has not been released to the FAA, the ATC facility issues a clearance that ensures the aircraft avoids the restricted airspace.

Restricted areas are charted with an “R” followed by a number (e.g., R­4401) and are depicted on the en route chart appropriate for use at the altitude or flight level (FL) being flown.
Term
What are Warning Areas?
Definition
Warning areas are similar in nature to restricted areas; however, the United States government does not have sole jurisdiction over the airspace. A warning area is airspace of defined dimensions, extending from 3 NM outward from the coast of the United States, containing activity that may be hazardous to nonparticipating aircraft. The purpose of such areas is to warn nonparticipating pilots of the potential danger. A warning area may be located over domestic or international waters or both. The airspace is designated with a “W” followed by a number (e.g., W­237).
Term
What are Military Operation Areas (MOAs)?
Definition
MOAs consist of airspace with defined vertical and lateral limits established for the purpose of separating certain military training activities from IFR traffic. Whenever an MOA is being used, nonparticipating IFR traffic may be cleared through an MOA if IFR separation can be provided by ATC. Otherwise, ATC reroutes or restricts nonparticipating IFR traffic. MOAs are depicted on sectional, VFR terminal area, and en route low altitude charts and are not numbered. However, the MOA is also further defined on the back of the sectional charts with times of operation, altitudes affected, and the controlling agency.
Term
What are Alert Areas?
Definition
Alert areas are depicted on aeronautical charts with an “A” followed by a number (e.g., A­211) to inform nonparticipating pilots of areas that may contain a high volume of pilot training or an unusual type of aerial activity. Pilots should exercise caution in alert areas. All activity within an alert area shall be conducted in accordance with regulations, without waiver, and pilots of participating aircraft, as well as pilots transiting the area, shall be equally responsible for collision avoidance.
Term
What are Controlled Firing Areas (CFAs)?
Definition
CFAs contain activities that, if not conducted in a controlled environment, could be hazardous to nonparticipating aircraft. The difference between CFAs and other special use airspace is that activities must be suspended when a spotter aircraft, radar, or ground lookout position indicates an aircraft might be approaching the area. There is no need to chart CFAs since they do not cause a nonparticipating aircraft to change its flight path.
Term
What are Other Airspace Areas?
Definition
“Other airspace areas” is a general term referring to the majority of the remaining airspace. It includes:
-Local airport advisory (LAA)
-Military training route (MTR)
-Temporary flight restriction (TFR)-Parachute jump aircraft operations
-Published VFR routes
-Terminal radar service area (TRSA)-National security area (NSA)
-Air Defense Identification Zones (ADIZ) land and water based and need for Defense VFR (DVFR) flight plan to operate VFR in this airspace

AGL
-National Oceanic and Atmospheric
Administration (NOAA) Marine Areas off the coast with requirement to operate above 2,000 AGL
-Tethered Balloons for observation and weather recordings that extend on cables up to 60,000 feet
Term
What does FAA 14 CFR Part 107 NOT apply to?

Term
Is a Visual Observer required for sUAS operations?
Definition
No, but the use of a VO is permitted.
Term
What is a First-person view camera and how may it be used during sUAS operations?
Definition
First-person view (FPV) is the ability of the user of some technology to see from a particular visual perspective other than one's actual location. FPV equipment cannot satisfy the “see-and-avoid” requirement but can be used as long as requirement is satisfied in other ways (e.g., using a VO).

Term
May a sUAS remote PIC disregard any of the rules and regulations under (14 CFR) Part 107 sUAS?
Definition
A remote pilot in command may deviate from the requirements of this rule in response to an in-flight emergency.
Term
What does a VO do?
Definition
A Visual Observer (VO) is a person who is designated by the remote pilot in command to assist the remote pilot in command and the person manipulating the flight controls of the small UAS to see and avoid other air traffic or objects aloft or on the ground.

Term
How should communication of VLOS information between the remote PIC, the person manipulating the controls and the VO be handled?
Definition
The remote PIC, person manipulating the controls, and VO must work out a method of effective communication, which does not create a distraction and allows them to understand each other. The communication method must be determined prior to operation. This effective communication requirement would permit the use of
communication-assisting devices, such as a hand-held radio, to facilitate communication from a distance.
Term
What must the remote PIC ensure when working with a VO?
Definition
That the VO can carry out his or her duties by ensuring that the VO is positioned in a location where he or she is able to see the small UA sufficiently to maintain VLOS.
The remote PIC can do this by specifying the location of the VO.
The FAA also requires that the remote PIC and VO coordinate to
1. scan the airspace where the small UA is operating for any potential collision hazard, and
2. maintain awareness of the position of the small UA through direct visual observation. This would be accomplished by the VO maintaining visual contact with the small UA and the surrounding airspace, and then communicating to the remote PIC and person manipulating the controls the flight status of the small UA and any hazards which may enter the area of operation, so that the remote PIC or person manipulating the controls can take appropriate action.

2. No person may operate a small unmanned aircraft so close to another aircraft as to create a collision hazard.

Circular notice text:

Unless the flight is conducted within controlled airspace, no notification or authorization is necessary to operate at or near an airport. When operating in the vicinity of an airport, the remote PIC must be aware of all traffic patterns and approach corridors to runways and landing areas. The remote PIC must avoid operating anywhere that the presence of the sUAS may interfere with operations at the airport, such as approach corridors, taxiways, runways, or helipads. Furthermore, the remote PIC must yield right-of-way to all other aircraft, including aircraft operating on the surface of the airport.

Remote PICs are prohibited from operating their small UA in a manner that interferes with operations and traffic patterns at airports, heliports, and seaplane bases. While a small UA must always yield right-of-way to a manned aircraft, a manned aircraft may alter its flightpath, delay its landing, or take off in order to avoid an sUAS that may present a potential conflict or otherwise affect the safe outcome of the flight. For example, a UA hovering 200 feet above a runway may cause a manned aircraft holding short of the runway to delay takeoff, or a manned aircraft on the downwind leg of the pattern to delay landing. While the UA in this scenario would not pose an immediate traffic conflict to the aircraft on the downwind leg of the traffic pattern or to the aircraft intending to take off, nor would it violate the right-of-way provision of § 107.37(a), the small UA would have interfered with the operations of the traffic pattern at an airport.

In order to avoid interfering with operations in a traffic pattern, remote PICs should avoid operating in the traffic pattern or published approach corridors used by manned aircraft. When operational necessity requires the remote PIC to operate at an airport in uncontrolled airspace, the remote PIC should operate the small UA in such a way that the manned aircraft pilot does not need to alter his or her flightpath in the traffic pattern or on a published instrument approach in order to avoid a potential collision. Because remote PICs have an obligation to yield right-of-way to all other aircraft and avoid interfering in traffic pattern operations, the FAA expects that most remote PICs will avoid operating in the vicinity of airports because their aircraft generally do not require airport infrastructure, and the concentration of other aircraft increases in the vicinity of airports.

May a SUA fly over a human being?
Definition
No person may operate a small unmanned aircraft over a human being unless that human being is:
1. Directly participating in the operation of the small unmanned aircraft; or
2. Located under a covered structure or inside a stationary vehicle that can provide reasonable protection from a falling small unmanned aircraft.

Note:

The remote pilot needs to take into account the small unmanned aircraft’s course, speed, and trajectory, including the possibility of a catastrophic failure, to determine if the small unmanned aircraft would go over or strike a person not directly involved in the flight operation (non-participant).

the FAA currently allows small unmanned aircraft flight over people in only one type of situation: a closed-set movie set which is a controlled-access environment where the person in charge has extensive control over the positioning of people who are standing near the small unmanned aircraft. The FAA currently considers each movie-set exemption on a case-by-case basis through the section 333 exemption process. The FAA will continue considering flight over people on a movieset on a case-by-case basis through the waiver process in this rule. The FAA notes that this framework is consistent with the regulatory framework used for motion picture and television filming in manned-aircraft operations, where a waiver is usually required prior to using an aircraft for filming purposes.103 The FAA also notes that, as discussed in section II.C of this preamble, current section 333 exemption holders who are allowed to fly over people when filming a movie will be permitted to continue operating under their section 333 exemption until they are able to obtain a waiver under part 107. With regard to flight over people in other controlled-access environments, such as construction sites, the FAA will consider that issue on a case-by-case basis through the waiver process.
Term
What airspace may a SUA not operate without a prior authorization from ATC?
Definition
No person may operate a small unmanned aircraft in Class B, Class C, or Class D airspace or within the lateral boundaries of the surface area of Class E airspace designated for an airport.*

*2018 Memorandum clarification:

In reviewing Class E Surface Area authorization requirements, we determined that the Class E authorization requirement only pertains to Class E surface areas for an airport, not the Class E extensions to Class D, C and E airspaces.

it does not require authorization for class E airspace everywhere but only Class E (1) at the surface and (2) in connection with an airport airspace. Also, you scan fly at night in some of these B, C,D, and E at the surface airspaces, because they change into G at night. You can fly under a night waiver near them.
