- ROL/TO Weight ON Wheels
- ROL/GA Weight OFF Wheels
3) Navigation leg sequencing past runway fix activated
4) Navigation source changed to GPS/FMS
What are some conditions that induce AP/YD failure
1) Integrated Avionics Unit (GIA) 1 or 2 failure
2) AHRS 1 or 2 failure/ mis-compare
3) ADS 1 or 2 failure/ mis-compare
4) Flight Control Electronics (FCE) 2 failure
5) Stall Warning.
How are pitch trim commands issued when the AP is engaged
The autopilot commands the Flight Controls Electronics (FCE) 2 which in turn commands the pitch trim actuator
Do AFCS servos control the aileron and rudder trim
No, Stabilizer trim only
How is the climb or descent rate controlled in FLC mode?
Using the thrust levers
Does the AFCS allow a climb or descent away from the selected altitude while in FLC mode?
No
In which vertical modes will the AFCS capture a selected lower altitude?
1) PIT
2) VS
3) VPATH/PATH
4) ALTV
5) FLC
In which vertical modes will the AFCS not capture a selected lower altitude?
1) GS
2) GP
Does GP capture when SUSP is annunciated on the HSI?
No
