Push & Start Flashcards
(27 cards)
What are abnormal engine-start indications?
No N1 rotation before the engine start lever is raised to IDLE detent; No oil pressure indication by the time the engine is stabilized at idle; No increase in EGT within 15s of raising the engine start lever to idle; No increase, or very slow increase in N1 or N2 after EGT indication; EGT rapidly approaching or exceeding the start limit; EEC abnormal start protection activation.
These indications require immediate attention and appropriate actions to prevent damage to the engine.
What should be informed to MAINTROL after an engine aborted start?
Aborted Engine Start NNC completed; Engine start parameters (flashing white boxes), any additional observations.
This communication ensures proper tracking of the incident and necessary follow-up actions.
Before taxi recall illuminated, which should be referenced, QRH or MEL?
MEL until the aircraft begins to move under its own power; however, the commander should exercise sound judgement in deciding whether to continue.
This decision is crucial for ensuring safety during taxi operations.
What actions should be taken for a Configuration Warning on line up due to parking brake?
Understand which item is not in position; release parking brake; continue with take-off.
This procedure helps in rectifying configuration issues before take-off.
What to do if ATC reports a big fire at the back while starting engines?
Accomplish the NNC; monitor engine; inform flight attendants to prevent inappropriate evacuation; communicate with ground personnel and ATC; call fire brigade if necessary.
This response is crucial for managing potential emergencies without causing panic.
What are the stabilized idle indications for the CFM LEAP 1B and CFM56 engines?
CFM LEAP 1B: N1 20%, N2 70%, EGT 500ºC, Fuel flow 272KgPH; CFM56: N1 20%, N2 59%, EGT 410ºC, Fuel flow 272KgPH.
These parameters ensure the engines are operating within safe limits.
What is the taxi out procedure in freezing conditions?
Do not retract flaps to less than F15 until the flap area is checked; stabilizer trim 5 units; Probe heat ON; Call engineer to check contamination and clean the flaps before retraction.
This procedure prevents ice accumulation and ensures safe operation.
What is the procedure for an engine fuel leak during startup?
Engine start may be continued; if it continues after engine is stable at idle: shutdown the engine and restart it. If it continues, let it run for 5min, if not, shutdown the engine and contact MAINTROL. Do a techlog entry.
Proper documentation and communication are essential for safety and maintenance.
What are the actions and memory items for an engine fire on the ground?
Thrust levers _ close; Parking brake _ set; Advise Cabin; Engine start lever (affected engine) _ CUTOFF; Engine fire switch (affected engine) _ Pull; Engine fire switch (affected engine) _ rotate to the stop and hold for 1 second.
Quick reaction is vital to mitigate fire hazards.
What are the conditions for one engine taxi?
Avoid thrust levels in excess of 40%; After landing checklist completed; no LVO; no freezing conditions; no contamination present; Actual gross weight <63T NG, <65T MAX; no conflicting NNC/HIL/MEL/DDPG; taxiway accommodates use of minimum thrust; no NOTAMs affecting.
These conditions ensure safe operation during taxi with one engine.
What is the procedure for cross bleed start if the APU is inoperative?
Need a bleed air source to start engines; can use an External Air Cart; start engine nr1, set parking brake, inform ATC, confirm area behind is clear, start engine nr 2 using bleed from engine nr 1 according to supplementary procedures FCOM.
This ensures engines can be started safely without APU.
What is the procedure for rapid disembarkation for GPU fire?
Initiate rapid disembarkation; Command: ‘Disembark the passengers immediately using all available doors’.
This procedure is critical during emergencies to ensure passenger safety.
What is the new taxi procedure regarding taxi clearance limits?
During taxi, FO will announce all taxi instructions, turning points, and taxi clearance limits in sequence over the interphone.
This enhances communication and situational awareness during taxiing.
Where can you find information on making a 180º turn while taxiing?
FCTM under chapter 2 – ground operations – taxi - turns of 180º.
This manual provides essential guidelines for safe ground operations.
What is the Isolated Pack procedure?
Allows operation of one pack while starting engine nr1; useful in hot environments.
This procedure helps maintain cabin comfort during engine start.
What does it mean if the Pack light is extinguishable on taxi?
Pack light + Master Caution + Air Cond due to both primary and standby pack failure; Pack will still operate without control.
Understanding these indicators is crucial for effective troubleshooting.
What does a Pack light at the holding point indicate?
Can be due to primary and secondary pack controls failed or pack overheat; check the MEL and proceed with QRH.
Proper management of pack operations is vital for maintaining pressurization.
What does a white box flashing during engine start indicate?
EGT flashing white box indicates EEC sensed impending hot start or compressor stall.
This alert requires immediate corrective action to prevent engine damage.
When do you unlock the flight deck door on the ground?
After L1 door is opened.
This procedure is important for security and safety protocols.
How to manage the crew if Nr1 reports sick before boarding?
Inform Dublin operations.
This ensures crew management is handled efficiently.
What are the actions after a runway incursion?
Immediately notify ATC; safely vacate the runway if visibility allows; pull CVR CB at the earliest opportunity.
Timely reporting and corrective actions are crucial for aviation safety.
What actions should be taken for an APU fire during taxi?
Stop the aircraft; set parking brake; inform cabin: ‘cabin crew standby’; APU fire memory items; inform ATC; monitor situation.
Immediate actions are essential to manage the incident effectively.
What is the threat from backtracking at 50kts?
Brake cooling is compromised for rejected take-off.
This can lead to safety hazards during take-off.
What should be checked if one wing is contaminated?
Check for de-icing capacity on AFB and company NOTAMS; local contamination removal; holdover time not applicable; symmetrical check; aerodynamic reason for full 24k.
Proper de-icing procedures are critical for flight safety.
