-Steamlining mode
What actions occur when the TO/GA button is pressed?
-Autopilot disengaged
-AFCS lateral and Vertical modes activated:
-ROL/TO Weight on Wheels
-ROL/GA Weight off Wheels
-Navigation leg sequencing past runway fix activated
-Navigation source changed from GPS/FMS
What are some conditions that induce AP/YD failure?
-Integrated Avionics Unit (GIA) 1 or 2 failure
-AHRS 1 or 2 failure/ miscompare
-Air Data System (ADS) 1 or 2 failure /miscompare
-Flight Controls Electronics (FCE) 2 failure
-Stall Warning
How are pitch trim commands issued when the autopilot is engaged?
The autopilot commands Flight Controls Electronics (FCE) 2 which in turn commands the pitch trim actuator.
How is climb or descent controlled in FLC mode?
Using the thrust levers
Does the AFCS allow 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?
-PIT
-VS
-VPATH/PATH
-ALTV
-FLC
In which vertical modes will the AFCS not capture a selected lower altitude?
-GS
-GP
Does GP capture when SUSP is annunciated on the HSI?
No
Does Gp capture if the CDI is not centered?
No
Describe the lateral function of ROL mode
Activated at bank angle:
-6 degrees or below: commands wings level
- Between 6 & 30 degrees: Commands present bank angle
-30 degrees or above: Commands 30 degree bank angle
Describe the vertical function of TO (Weight on Wheels)
Flaps 1: Constant 10.5 deg pitch attitude
Flaps 2: Constant 8 deg pitch attitude
Describe the vertical function of GA (Weight on Wheels)

-Flaps FULL: Constant 6 deg pitch attitude
-
Is Low Bank mode available in both HDG and NAV (FMS/VOR/LOC)?
Yes
In heading mode, are turns commanded in the same direction as selected heading bug movement, even if the bug is turned more than 180 deg from the present heading?
Yes
