Term
 What are three common ways to navigate?
Definition
Term
 Types of aeronautical charts available for use in VFR navigation
Definition
 Sectional Charts:  1" = 6.86 nm Terminal Area Charts: 1" = 3.43 nm.  Depict Class B airspace VFR Flyways:  flight paths and altitudes recommended for bypass of high traffic areas
Term
 What is an isogonic line?
Definition
 Shown as broken magenta lines, they connect points of equal magnetic variation.  They show the amount and direction of magnetic variation.
Term
 Magnetic Variation
Definition
 The angle between true north and magnetic north.  Expressed as east variation or west variation depending upon whether magnetic north (MN) is to the east or west of true north
Term
 Within which frequency range do VOR's operate?
Definition
 In the very high frequency (VHF) band between 108-117.95
Term
Definition
 A line of magnetic bearing extending from a VOR
Term
 How are VOR NAVAIDS classified?
Definition
 Terminal, low, and high
Term
 What reception distance can be expected from a class T VOR?
Definition
 12,000 feet and below 25 nm
Term
 What reception distance can be expected from a class-L VOR?
Definition
 Below 18,000 feet and 40 nm
Term
 What limitations apply to VOR reception distances?
Definition
 Line-of-sight restrictions and the range varies proportionally to the altitude of the receiving equipment
Term
 What are the different methods for checking the accuracy of VOR receiver equipment?
Definition
 VOT check  (+/- 4 degrees) Ground checkpoint  (+/- 4 degrees) Airborne checkpoint (+/- 6 degrees) Dual VOR check (+/- 4 degrees) Selected radial over a known ground point (+/- 6)
Term
 What is "DME"
Definition
 Distance Measuring Equipment (airborne and ground):  used to measure, in nautical miles, the slant range distance of an aircraft from the DME navigational aid.  Aircraft equipped with DME are provided with distance and ground speed information when receiving VORTAC or TACAN facility.  Operates on UHF frequencies between 960-1215 MHz
Term
 Three functional elements of GPS
Definition
 Space element:  consists of 30 satellites Control element:  consists of a network of ground-based GPS monitoring and control stations that ensure the accuracy of satellite positions and their clocks User elements:  consists of antennas and receiver-processors onboard aircraft that provide positioning, velocity, and precise timing to the user
Term
 What is RAIM
Definition
Term
 What is the purpose of RAIM
Definition
 Self-monitoring function performed by a GPS receiver to ensure that adequate GPS signals are being received from the satellites at all times.  The GPS will alert the pilot whenever the integrity monitoring determines that the GPS signals do not meet the criteria for safe navigational use.
Term
 3 ways to obtain RAIM availability information
Definition
 Manufacturer-Supplied RAIM prediction tool Service Availability Prediction Tool on the FAA enroute and terminal RAIM prediction website GPS RAIM aeronautical information from an FSS during preflight briefings
Term
 If RAIM capability is lost in flight, can you continue to use GPS for navigation?
Definition
 Without RAIM capability, the pilot has no assurance of the accuracy of the GPS position.  VFR GPS panel-mount receivers and handheld units have no RAIM alerting capability.  This prevents the pilot from being alerted to the loss of the required number of satellites in view or the detection of a position error
Term
 Before conducting a flight using GPS equipment for navigation, what basic preflight checks should be made?
Definition
 Verify the GPS equipment is properly installed and certified for the planned navigation Verify that the databases (navigation, terrain, obstacle, etc.) have not expired Review GPS NOTAM/RAIM information related to the planned route of flight Review operational status of ground-based NAVAIDs and related aircraft equipment (30 day VOR check) appropriate to the route of flight Determine that the GPS receiver operation manual or airplane flight manual supplement is onboard and available for use
Term
 During a preflight briefing, will the FSS briefer automatically provide a pilot with GPS NOTAMs?
Definition
 No.  You must specifically request GPS/WAAS NOTAMs
Term
 How many satellites does a GPS receiver require to compute its position?
Definition
 3 satellites - yields a latitude and longitude position only (2D) 4 satellites - yields lat, long, and altitude position (3D) 5 satellites - 3D and RAIM 6 satellites - 3D and RAIM (isolates corrupt signal and removes from navigation solution
Term
 What is WAAS?
Definition
 Wide area augmentation system.  A ground and satellite integrated navigational error correction system the provides accuracy enhancements to signals received from the global positioning system.  Provides extremely accurate lateral and vertical navigation signals to aircraft equipped with
Term
 Pressure Altitude Formula
Definition
 PA = (29.92-ALT) X 1000 + FE
Term
 Density Altitude Formula
Definition
 PA + 120(OAT - ISA)   ISA = 15 C or 59 F
Term
 After takeoff, you attempt to activate your VFR flight plan but are unable to contact the FSS.  What will happen to you filed flight plan?
Definition
 When a VFR flight plan is filed, it is held by the FSS until 1 hour after the proposed departure time and then is cancelled
Term
 If it becomes apparent that you cannot locate your position, what action is recommended at this point?
Definition
 5 C's Climb - higher altitude allows better communication and visual range Communicate - 121.5 if necessary Confess Comply Conserve
