What is the operating length of the Helicopter(Front tip of MRB to back tip of TRB)
64 feet 10 inches
What is the Main rotor diameter?
53 feet 8 inches
What are the rules for a helicopter flying an instrument approach using straight-in MDA or DH while intending to circle-to-land.

=> This may be done as long as circle-to-land can be done within 500 feet of runway centerline and the helicopter remains within airport boundaries

=>Departure and arrival weather requirements can not be predicated upon this ability

Where are the float bottles for the flotation system stored?
Underneath the nose compartment

1. What impact G-force will set off the ELT transmitter?


2. What freq's does the ELT transmit on when placed to on?


3. How long will the ELT transmit for?




1. 2.6G's


2. 121.5 234.00 and 406.025


3. 24 hours of use at 406.025 and 48 hours of use on 121.5 and 243.00. transmission occur every 48-52 seconds on 406

What are the 3710 rules regarding using the primary navigation source while flying an instrument approach 

=> The pilot's primary navigation shall be set to the NAVAID named in the approach title prior to commencing the approach segment

=> Only the primary navigation source shall provide guidance while on the final approach segment of a coupled approach

What are the OPNAV requirements for using GPS navigation?

=> If not IFR certified, aircraft navigation shall not be predicated solely upon GPS. It may be used to confirm other navigation sources

=> P-codes or selective availability shall be used when available unless a certified non-military operating mode is more appropriate

=> If navigating solely by GPS, it shall be NGA approved or have an FAA letter of acceptance if a commercial vendor. (Verify GPS validity in accordance with the AIM)

=> Unit CO's may approve expired navigation data if it can be verified for correctness and the instrument provedures haven't been amended(verify using current PUBS). AVOID MAKING CRITICAL NAVIGATIONAL DECISIONS


What are the GPS navigation filing requirements per the AIM?

AIM 5-1-8 d(2)

a) File airport to airport

b) File the appropriate RNAV suffix

c) plan to begin and end over appropriate fixes or NAVAIDS

d) File route structure transitions to and from the random route portion of the flight

e) Define randomn routes by waypoints

f) File a minimum of 1 route description waypoint for each ARTCC through whose area the randomn route will be flown. These waypoints must be located within 200NM of the preceding center's boundary

g) File an additional route description waypoint for each turnpoint in the route.

h) plan additional route description waypoints as required to ensure accurate navigation via the filed route of flight

i) Plan the route of flight so as to avoid prohibited and restricted airspace by 3NM unless permission has been obtained to operate that airspace and the appropriate ATC facilities are advised.




An instrument approach may be started and flown to minimums when the reported weather is below minimums;however, the pilot will not descend below the published minimum descent altitude/decision altitude(MDA/DA), or land, unless he or she can what?

=> Proceed with a Contact approach

=> Comply with 14 CFR 91.175

(1) Aircraft is continually in a position to land using a normal rate of descent

(2) the flight visibility is not less the required visibility for the approach

(3) At least one of the following is distinctly visible and identifiable

i) Approach light system, except the pilot may not descend below 100 feet above the touchdown zone elevation using the approach light as a reference unless the red terminating bars or the red side row bars are also distinctly visible and identifiable

ii) The Threshold

iii) The Threshold markings

iv) The threshold lights

v) the runway end identifier lights

vi) Visual approach slope indicator

vii) Touchdown zone or touchdown zone markings

viii) touchdown zone lights

ix) Runway or runway markings

x) Runway lights

What is a Contact Approach?

=> Aircraft is on an IFR flight plan, operating with ATC authorization

=> Clear of Clouds with at least 1 s.m. Visibility and the airport ground visibility is also 1 s.m.

=> Reasonable expectation of continuing to the destination airport in those conditions

=> Deviates from the IAP and proceeds to the destination airport by visual reference to the surface

=> Will only be granted if the pilot asks.

What risk to the Aircraft and Aircrew is Warranted in the defense of the United States, its citizens, or installations?

1) Risk of damage to or sacrifice of the aircrew and aircraft is acceptable



Warranted Risk for SAR:
Saving a Human life warrants maximum effort. If no suitable alternative exists, and the mission has a reasonable chance of success, can the aircrew or aircraft be risked to save human life?


1) Probable loss of aircrew is not acceptable risk.

2) Risk of damage/abuse/non-recovery of the aircraft is acceptable



If a mission is likely to prevent/relieve intense pain/suffering, or saving human life is possible, what risk to the aircrew and aircraft is warranted?


1) Risk to the aircrew is not acceptable

2) Risk of damage/abuse to the aircraft is acceptable is recovering the aircraft can be reasonably expected

WARRANTED RISK FOR SAR: If a mission is likely to save property of the US/citizens, is risk to the aircrew or aircraft acceptable?

1)Risk of damage to the aircraft is warranted ONLY IF the value of the property is UNQUESTIONABLY greater than the cost of aircraft damage, AND the aircraft is fully expected to be recovered

Is risk of damage to aircrew/aircraft acceptable in the interest of LE or Evidence?
Does Logistics or missions with little or no urgency warrant risk to the aircrew or aircraft?
No, these flights shall not be prosecuted if they expose the aircraft to hazards greater than those encountered during the course of routine training missions
