After 2 seconds A/P disconnect.
ILS AUTO LAND steps
ILS anomaly or failure- A/P disengage.
Hydraulic failure A or B - both A/P disengages.
Below 1500ft - ILS deviation test, FLARE armed, second A/P couples with flight controls.
800ft - Second A/P must be engaged
500ft - verify FLARE armed, no steady A/P WARNING light.
400ft - nose up trim, FLARE not armed A/P disengage by 350ft.
50ft - FLARE engaged, FD bars retract.
27ft - A/T RETARD.
Rollout - A/T disconnect 2 seconds after touchdown.
Pushing TO/GA single A/P -below 2000ft RA -flaps not up -GS green Pushing TO/GA single A/P -above 2000ft RA with flaps not up -GS green Pushing TO/GA after touchdown. Using Control will switch trim. IRS System failure. Loss of electrical power. Loss of hydraulic power.
Independent F/D operation
No A/P engaged. Both F/D on. And one of the following: - APP engaged with LOC and GS captured -GA or TO mode engaged below 400ft RA
TO/GA - go around
- inflight below 2000 feet radio altitude
- inflight above 2000 feet radio altitude
- not in takeoff mode
- either F/D ON or OFFf
- if the TOGA switches are activated after touchdown (wheel spin-up)
On any heading up to 3nm.
More then 3nm, 90 degrees or less and interception before active point.
Second press on TO/GA below/above 800ft AGL
second press of the TO/GA switch below 800 feet above field elevation will change the thrust limit mode to GA and
N1 reference bugs to increase to full GA thrust, thrust levers will not be in motion.
A second press of the TO/GA switch above 800 feet above field
elevation, thrust levers advance toward full GA thrust
