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
NR decreasing from 100-96% with an increase in Q during steady flight with no engine malfunction, what’s happening?
main transmission planetary carrier may have failed
Main Transmission Failure WARNING
-what is primary consideration?
land helicopter before failure progresses to gear box seizure or loss of drive to main and or tail rotor.
Load Demand System Malfunctions
What positions can it fail to?
Full open or partial/stuck
Basic Rules that apply to all aircraft emergencies
- Maintain aircraft control
- Analyze the situation
- Take proper action
- Refer to the checklist if time permits
Land As Soon as Possible
A landing be made at the first available area which will assure minimal injury to crew/damage to the aircraft.
Land as Soon as Practical
No injury to the crew or damage to the aircraft and acceptable access for corrective actions.
PTO -1
WARNING Going to EDECU lockout does not remove what?
NG limiting or max fuel flow.
PTO -1
What is the minimum egress with munitions and flares onboard?
600’
PTO -1
When will FUEL 1 LOW or FUEL 2 LOW cautions illuminate?
Fuel level decreases to 250lbs in each tank.
Indicates a low fuel condition exists.
PTO -1
What indication is there when a main fuel quantity status is failed?
Black text on red background, digital readout is displayed as three red dashes.
PTO -1
What indication is there that a miscompare condition existsin the fuel system?
MAIN FUEL tape label will display as black text on a yellow background.
PTO -1
When will the MAIN FUEL tape and digital readout (along with the TOTAL digital readout) turn yellow?
Below 300lbs
What equipment will we have battery only? (no AC)
- Pilots inboard MFD, FMS, FD/DCP
- No 2 ADC
- No 2 DCU
- No 2 EGI
- No 1 stabilator
- LPCAPs
- Coms 1-5
- RADALT
- digital clock
- IFF/SIF
- VOR/ILS
- searchlight
- IVHMS
PTO -1
WARNING Associated with losing DC Primary power?
It will result in the engine anti-ice and engine inlet anti ice failing to the open position. This will result in reduced power up to 20% Q per engine. The advisory lights will not illuminate due to the loss of electrical power.
PTO -1
How long will the auxiliary bearing operate for?
10 additional hours of operation after the caution illuminates.
PTO -1
How is emergency electrical power provided?
A generator driven by the APU
ENG OUT audio
NG below 55%
Low Rotor RPM
NR is below approximately 96%
FUEL DUMP FAIL caution condition
FUEL DUMP switch is in the DUMP position and no fuel dump flow has been detected within 25 seconds
FUEL DUMP ON caution condition
FUEL DUMP switch is in the OFF position and fuel dump flow has been detected.
FUEL 1/2 LOW caution condition
Tank is below approximately 250lbs
FUEL PROBE FAIL caution conditions
Fuel probe has been in the unlocked state for more than 60 seconds.
