NATOPS GOTCHAS Exam Questions
With 100% Verified Answers.
Aircraft Dimensions - ✔✔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 - ✔✔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) - ✔✔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) - ✔✔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
150#/hr if APU running ECS
64#/hr with bleed air on and ENG ANTI-ICE - ON
10#/ hr with bleed air on and HEATER- ON
FUEL TYPES - ✔✔Primary - fuel that the aircraft is authorized to use for continuous
unrestricted operations (JP-5, JP-8, A++/F-24, TS-1 from US/NATO mil installations only)
Restricted - fuel that imposes operational restrictions on the aircraft (Jet-A1, Jet-A, Jet-B, JP-4)
Emergency - fuel which may be used for a minimum time when no other primary or
restricted fuels available in case of emergency of operational necessity (JP-8+100, F-27)
RESTRICTED FUEL RESTRICTIONS (4) - ✔✔1. All T/O shall stabilize in a hover with
no fuel pressure cautions for a min 10 sec before commencing transition to forward flight
2. Single-engine training is prohibited
3. Operating characteristics may change (lower operating temp., slower acceleration, and
shorter range may be experienced)
, 4. Due to vapor qualities of mixed JP-4/Jet-B, the next 2 refuelings with primary fuel shall be
treated as if JP-4/Jet-B is in the tanks.
SHIPBOARD FUEL RESTRICTION - ✔✔Helicopter should be fueled JP-5 prior to flying
aboard a ship to ensure safe hangaring.
When this is not possible, helicopters shall not be hangared until the flashpoint of the fuel in the
fuel tanks is > 120° F.
JP-8, TS-1, JP-4, JP-8+100, F-24 and all commercial Jet fuels shall not be defueled
into shipboard JP-5 storage tanks because the flashpoint of these fuels is < 140° F.
For planning purposes, a fuel mixture of 70% JP-5 and 30% JP-8/Jet A-1 will ensure the
min flashpoint of the fuel mixture is > 120° F.
EXCEEDING A LIMIT - ✔✔Any time an operational limit is exceeded an entry shall be
made on a MAF, which should include the limit exceeded, range, duration, and any
additional data that would aid Mx.
If a limit is exceeded to the extent that a red "XXX" is indicated, the crew should land as soon as
practicable.
CHIP IBIT Test - ✔✔~ 2 min to verify function of circuitry and the individual detectors
For approx. the first 40 sec of the test 28 Vdc is interrupted and WCAs and
MASTER CAUTION lights will not correctly respond
FAIL indicates circuitry or chip detector failed, not that there is a chip
**Test will not function without the primary and backup computer on**
