NATOPS GOTCHAS EXAM QUESTIONS
WITH VERIFIED ANSWERS
Purpose of NATOPS - ANSWER The Naval Air Training and Operating
Procedures Standardization Program is a positive approach to improving
combat readiness and achieving a substantial reduction in aircraft
mishap rates.
NATOPS Defintion and Scope - ANSWER NATOPS manuals are issued
by the authority of the Chief of Naval Operations and under the direction
of the Commander, Naval Air Systems Command in conjunction with the
Naval Air Training and Operating Procedures
Standardization (NATOPS) program.
NATOPS products provide the best available T/M/S aircraft information
and operating instructions for most circumstances.
However, no manual can cover every situation or be a substitute for
sound judgment; operational situations may require modification of the
procedures contained therein.
Read these products thoroughly. As an aircrew member, it is your
responsibility to have a complete knowledge of their contents.

What constitutes a head check? - ANSWER Blade Lockpin (engaging
microswitch)
Pitch Lock Actuator (pitch locks not engaged)
Gust lock (not engaged)
What must be visually inspected if the PYLON FLIGHT light is not
illuminated during Prestarts? - ANSWER Pylon and STAB lockpins and
the T/R indexer; failure to do so may cause separation of the tail pylon
What 5 items make up the "FLIGHT" light - ANSWER 5° switch (inside
pylon)
Microswitch outside pylon on STBD side (engaged)
PORT STAB lockpin/keeper (keeper in place)
STBD STAB lockpin/keeper (keeper in place)
T/R indexer (retracted)
4 WAYS TO CORRECT CABLE ANGLE HOVER - ANSWER 1. Use
cyclic 4-way trim switch to command the aircraft in the corrective
direction.
2. Fly against lateral trim.
3. Using the trim release button, reposition the aircraft.
4. Fly against longitudinal trim.
WHY IS LONGITUDINAL TRIM THE LAST TO ADJUST WHEN
CORRECTING CABLE ANGLE? - ANSWER Any manual correction
against longitudinal trim of 3% (0.3 in) for ≥ 2 sec will cause AFCS to
remove Cable Angle hold solution in the longitudinal access and require
up to 20 sec to fully reincorporate the new longitudinal solution
, Aircraft Dimensions - ANSWER MR - 53' 8"
TR - 11'
Height - 9'5" to MR TPP with rotors engaged; 16' 10" to top of T/R; 6' 6"
to bottom of TR
Length Overall (Rotors Turning) - 64' 10"
Length Overall (Rotor/Pylon folded) - 42' 10"
Folded Width - 11' 7.5"
Prohibited Maneuvers - ANSWER 1. Aerobatic maneuvers
2. Practice full autorotation landings
3. Intentional approaches into or inducement of retreating blade stall
(per CNAF aerobatic maneuvers are):
1. Intentional maneuver involving an abrupt change in A/C attitude
2. Intentionally performed spins
3. Other maneuvers requiring Pitch/Dive Angle > 45°, AOB > 60°, or
accelerations > 2 Gs
4. A maneuver that conforms to the model NATOPS manual is not
considered aerobatic flight
What is PRIST? How is it used? (2) - ANSWER Fuel System Icing
Inhibitor (FSII) additive
2 forms:
1. discharged via aerosol cans (not authorized due to poor mixing ability)
2. premixed into fuel
"+" indicates a commercial fuel containing a FSII
Fuel Burn Rate Gouge for 20-23.5K GW @ 0 PA
(Max Range / Max Endurance / HOGE / ENG ANTI-ICE / ECS ON APU)
- ANSWER Max Range (~120 KIAS) - 1200-1300#/hr
Max End/Bucket (~70 KIAS) - 925-1025#/hr
HOGE - 1450-1550#/hr avg
Additional:
84#/hr in a HOGE with ENG ANTI-ICE - ON
