Takeoff Flashcards
Why is a static takeoff with a crosswind of 25 kts or greater not recommmended?
Possible compressor stall
On takeoff, what would cause a ENG TLA NOT TOGA EICAS message?
Anytime thrust levers are not TO/GA position
If the autothrottle is armed, at what TLA will it takeover and advance the thrust levers to the TO/GA position?
50 deg.TLA
When HOLD mode is activated what position should the thrust levers be in prior to reaching 60KIAS?
TO/GA
When will flex thrust takeoffs be utilized?
All takeoffs unless performance or other factor dictate otherwise
When are flex thrust takeoffs not authorized?
Special departures that prohibit reduced thrust, forcast wind shear, Contaminated runways
If REF ATTCS was set to ON in the takeoff data settings what four events will automatically cause the ATTCS to command max thrust?
Differential N1 values 15% or greater between engines, OEI, associated thrust lever moved to MAX detent, windshear detected
If LNAV was armed on the ground (during the CA W&B/PERF tasks) when will it automatically engage after takeoff?
200ft AGL
What speed should be maintained from 1,000AFE/Flap Retraction Altitude to 2,500ft AFE?
200KIAS then normal climb profile/speeds, unless operating in Class B airspace, then maintain 250KIAS or assigned
What guides flap retraction?
F-BUG
What should be done if the F-BUG disappears before flap retraction is complete?
Follow the green Dot +10 kts
During the after takeoff sequence, what should the PM do with/after each flap retraction?
airspeed bug must match VFS. If it doesn’t, PM adjusts bug to match VFS or flap limit speed, whichever is less.
When operating on contaminated runways what should the CA/PF ensure before takeoff thrust is applied?
Ensure runway alignment
What must be done just prior to setting takeoff thrust when performing a takeoff in icing conditions?
N1 shall be set to 54% for 30 seconds or until fan vibration returns to normal, just before takeoff power
What is the main cause of runway overrun during a rejected takeoff?
RTO performed above V1
Whose responsibility is it identify a possible RTO event or malfunction?
Whomever first notices an RTO worthy condition
Whose responsibility is it to actually perform the RTO?
The captain
If an RTO is performed below 60kts (before HOLD is displayed) and the autothrottle is not disconnected, what will happen?
If thrust levels have moved beyond 40 degrees TLA, autothrottle will move thrust levers back to TO/GA, if thrust levers are below 40 deg. TLA the AT will disconnect
Once the RTO decision is made, what is the first course of action?
Thrust levers, idle, ensure autobrake activation or maximum manual braking, reverse thrust as required
If an RTO is performed on a contaminated runway, how is maximum deceleration achieved?
Maximum reverse thrust and maximum braking
During an RTO is performed on a contaminated runway, if directional control problems develop, what steps should be followed to regain directional control?
Return reverse thrust to idle, and possibly forward thrust, regain centerline with nose wheel/rudder and/or differential braking
On a slick runway, during a RTO, directional control problems could develop or may be compounded by excessive anti-skid cycling, what should be done to correct this?
Reduce brake pressure
Tail strikes most often occur during what phase of flight?
Landing
On takeoff, what are the three primary causes for a tail strike?
improper stabilizer trim, rotation speed, rotation rate
