Non Normal OPS Flashcards
NMATE
#
3 categories of alerts?
Time Critical RED
Warnings RED
Cautions AMBER
Prioritize alerts and NNC how?
NNC with memory steps 1st
Time critical, warning or caution
System Knowledge
Reason for engine tailpipe fire?
EEC malfunction
Excess fuel in combustor, turbine, exhaust nozzle.
Oil in hot section flow path or exhaust system
Loss of engine thrust control?
Hard to recognize,
control loss may not be immediate
Fixed RPM or TL condition maybe near commanded thrust
Loss of thrust on both engines NNC written to ensure?
Crew take advantage of high RPM at engine failure regardless of alt or speed.
Bird strike indications?
Vibration due fan blade damage
EGT increase
Consider to evacuate>
Urgency?
Type of threat to AC?
Possibility of fire spreading rapidly from spilled fuel or materials.
Extent of AC damage
Possibility of Pax injury during emergency evacuation.
Alternate flap extension?
Set command speed only when flaps reached selected position.
Jammed flight controls why?
ice due water leaks into cables
dirt
component failure
improper lubrication
Foreign objects
Non jammed control requires what force?
Normal force plus additional override force.
4kg + 23kg override = 27kg
Jammed/Res flight control –when reduce thrust on landing?
only after touchdown
Reason for Stabilizer trip INOP?
Failed Stab motor = loss of elec trim via AP and control wheel switches.
Manual trim available.
*lodged/stuck stab motor =
*lodged/stuck stab actuator = all trim lost. cannot be trimmed.can be due ice on jackscrew.
Man Stab Trim, 1unit?
15 turns
STBY RUDDER on?
STBY rudder PCU operating.
Can be ON due crew action or HYD system malfunction. OR…
1)FFM malfunction - full rudder inputs avoided - prevent excessive load on rud. NNC is for this condition.
2) Press difference between two PCU control valves = jammed. Satisf rudder ops available using STBY RUDDER- no action needed.
Airspeed Unr memory items assumes?
all model/engine, all weight and alt.
Flap up setting - speed remains above stall end below over speed.
Flaps extended - speed remains above stall and below flap placard limit.
Biased towards higher speed - high energy state better.
Allow time to stabilize AC, remain within envelope without stall or overspeed.
Flap up and no up
Pitch and Thrust considerations?
Flap extend = pitch and thrust = climb
Flaps up pitch and thrust = slight climb at light weights and low alt, and slight descent at heavy weights and alt.
Light weight + L alt = TAS higher normal
Heavy weight + H alt = lower tas
Erroneous flight deck indications to assist crew to determine reliable airspeed indication?
1) Sshaker one side
2)airspeed low one side
3)PLI one side
Compare 2 airspeed?
Not conclusive
If, Unr Airsp caused by erroneous AOA,
AOA DISAGREE is shown PFD
Min/Max speed bars on one side
This case - compare indicated airspeeds with ISFD can help determine reliable indication.
AOA indicator used?
Adjust speed to maintain analog needle at 3 o’clock position.
Unr airspeed on TO?
TO thrust
rotate 15 deg pitch
Establish normal pitch attitude target
retract gear
maintain flap config
climb normal TO pitch until Safe Alt / acc height and do NNC.
Air Unr during App?/
GA thrust
15deg pitch
normal TO pitch
@safe alt
Set target pitch and thrust
App mode used during APP?
make sure to exit APP mode - push TOGA
Only STBY airspeed indication reliable?
DO not use TOGA
Altitude unreliable. AC TX send alt to ATC?
may be unreliable. Cant be used to verify alt.
Capt Alt indications not reliable?
Dont set minimums. Calls inaccurate.
Engine Fuel Leak NNC , assumes?
Fuel leak between front spar and engine.
Some reasons for suspected fuel leak?
1) Total fuel remaining less than planned fuel.
2)Fuel leak due to excessive engine fuel flow?Can be faulty FF meter or engine leak downstream of FF meter. Both will cause high FF. Compare Total fuel remaining vs Planned fuel remaining.
3) One main tank abnormal low compared to other main tanks and expected remaining fuel in tank. One low tank can be due leak, engine out or CFEED valve problem. Eng out and TOT vs Cal value is OK - no leak. TOTAL FUEL should match planned fuel - no leak.
Fuel Leak NNC leads crew to?
determine if fuel leak is from strut or engine area.
Why shut down engine with fuel leak?
1) close spar valve to stop leak. Prevents loss of fuel
2) Fire potential increased with leak
Landing gear jammed in Up position why?
mechanical jam or LG handle.
LG selector valve stuck in Up position.
Basically LG remains press in UP position.
Tire failure during TO?
LG can be retracted
Damage from failed tire?
Wheel well design and automatic wheel braking prevent damage from failed tire.
Landing flat tire?
Designed adequate strength to land on flat nose gear tire or main gear tire.
