BLADEFOLD switch is moved from OFF position

12
Q

if PYLON FLIGHT light is not illuminated

A

pylon and stabilator lockpins and tail rotor indexer shall be visually inspected prior to flight

13

A

mission comptuer has taken control

14
Q

while performing CHIP IBIT

A

28 VDC is interrupted

15
Q

during CHIP IBIT, WCAs and MASTER CAUTION will not correctly respond for

A

approx 40 seconds

16
Q

CHIP IBIT will not function without

A

primary and backup computer on

17
Q

on Fuel Quantity Test, should see

A

total fuel decreases to 0 (if external tank installed, total fuel will read what’s in external tank), #1/#2 FUEL LOW, MASTER CAUTION

18
Q

Good RadAlt Test

A

RadAlt tone 5 +/- 1 beeps, indicator reading 100 +/- 10 ft for 5 seconds, yellow tape up to DH setting or 100 ft, whichever is lower

19
Q

Good TACAN Test

A

BRG 1 needle 180 +/- 3 deg for 5 sec, DME 0.0 nm (+/- 0.5 nm), NAV needle centering (within 1/2 dot), a TO (if 180)/FROM (360) indication

20
Q

Good Transponder Test

A

Absence of IFF cautions or advisories

21
Q

Tail Rotor Servo Check

A
#1 TR SERVO
#2 TR SERVO ON
BKUP
MASTER CAUTION
no binds or restrictions while moving pedals
22
Q

AFCS Ground Checks Allowable movement

A

SAS 1/2 and trim - Minimal movement in flight controls acceptable
Autopilot - No movement in flight controls

23
Q

Helicopter shall not be flown if stab fails

A

any check involving manual operation, position indications, or warnings

24
Q

if stab auto mode fails to engage, ___ may align stab actuators and allow stab auto mode to reengage

A

slewing stab full up then full down with ac power

25
Q

Np shaft rub occurs due to

A

asymmetric heating of Np shaft by a hot engine

26
Q

Np shaft rub definition

A

when rotor brake is released, Np shaft impacts Ng shaft causing compressor blades to impact casing

27
Q

an unguarded cyclic may allow rotor arc to dip as low as

A

4 ft

A

hot start

29
Q

it is normal for OIL FLTR BYPASS caution and/or high engine oil pressure to appear when
