So You’re Flying Along… Flashcards
Single Engine Conditions
Collective - ADJUST
Airspeed - ADJUST
Engine anti-ice, cabin heater, and cockpit heater - OFF
Fuel/external cargo - DUMP or JETTISON
WARNING
If AC power is not available, what compartments will have fire protection?
With what fire bottle?
Only the No. 1 engine compartment or the APU compartment has fire protection.
Reserve fire bottle.
WARNING
Suspected Engine Compartment Fire
Visually confirm fire before engine shutdown
NOTE
Airspeed for discharging the fire extinguishers
Airspeed should be reduced to 100 KIAS or below before discharging fire extinguishers due to the airflow through the engine compartment at higher speeds
Dual Generator Failure Indications
CONV 1 FAIL and CONV 2 FAIL cautions
and
AC REF BUS DEGRAD advisory illuminate
WARNING
Loss of DC primary power in regards to power and advisory lights
Will result in the engine anti-ice and engine inlet anti-ice valves failing to the open position. This will reduce power available up to 20% Q per engine.
Respective ENG ANTI ICE advisory lights will not illuminate due to the loss of electrical power.
Battery Life
17 minutes
CONV 1 FAIL or CONV 2 FAIL caution illuminates checklist
There is none lol
Electrical power will be provided by the remaining system.
Post Engine Shutdown Fire Indications
Rise in TGT above 500 degree C after shutdown
and/or
excessive smoke from the engine exhaust
PTO - 1
BOOST SERVO OFF CAUTION ILLUMINATES indicates what?
A pilot valve jam in either the collective or yaw boost servo.
NOTE
During electrical malfunctions, even though it’s not listed as a checklist step, what should we be looking for?
Popped circuit breakers
NOTE
There isn’t a checklist for a single converter failure, but what can’t we do?
Turn off corresponding battery switch. It will cause the battery bus tie connector to close resulting in loss of all associated batter bus and DC essential bus.
WARNING with engine out audio
ENG OUT audio is not the sole indication of an engine failure and should be confirmed by verifying TGT, NG, and NP
T/R Quad Fail Caution
What will happen with one cable failure vs two?
one: if helicopter is shut down and or hydraulic power is removed, there’s no spring tension so quadrant spring will displace enough to unlatch the quadrant cable
two: a centering spring will position the tail rotor servo linkage to provide 10.5 degrees of pitch
Yaw Controllability Check
-CAUTION with airspeeds
-recommended type of landing
-airspeeds below target touchdown will result in right yaw
-shallow approach to rolling landing
