The Automatic Flight Control System (AFCS) panel. AOM 9-03-30
What does pushing the FD button on the AFCS panel do?
Engages and disengages the flight director on those PFD’s. AOM 9-03-30
What does pushing the AT button on the AFCS panel do?
Engages and disengages the auto throttle. AOM 9-03-30
What does the outer ring of the SPD knob do?
Select the source of the speed reference between MAN and FMS. AOM 9-03-30
What does pushing the HDG button on the AFCS panel do?
Select heading mode when pushed once and alternates with roll mode is pushed again. AOM 9-03-30
Pushing the BANK button on the AFCS will toggle between what bank angles?
+/- 15° and +/- 30° AOM 9-03-30
What is the up and down range of the FPA mode?
9.9° up and down. AOM 9-03-30
How can the flight path angle/reference line be selected?
By rotating the FPA knob. AOM 9-03-30
What does the outer knob of the ALT knob select? The inner knob?
Selects the altitude increasing/decreasing 1000 feet. Select the altitude increasing/decreasing 100 feet.
What does pushing the SRC button do?
Alternates between PFD 1 and PFD 2 FMA modes as the source for the auto pilot. AOM 9-03-30
When the autopilot is engaged, what does pushing the TCS button on the sidestick do?
It activates the TCS (AP override) as long as neither the takeoff nor go-around mode is active. AOM 9-03-30
Where are the AT/DISC buttons located? The TO/GA buttons?
On the thrust levers. AOM 9-03-30
With the AP engaged, will the AP disengage if the force is applied on the sidestick, either in the pitch or roll direction?
Yes. AOM 9-03-30
What are the two FD cues presented?
The flight director cue (a magenta circle) and the takeoff cross bar. AOM 9-03-30
What does the green Flight Path Vector cue indicate?
The current flight path in reference to the horizon line. AOM 9-03-30
Where is the Flight Mode Annunciator (FMA) located and what does it display?
On the upper part of both PFD’s; annunciation for auto throttle, autopilot, approach status, lateral and vertical modes. AOM 9-03-30
List the FMA color codes for normal operation.
- Magenta – For FMS active/engaged modes
- Green – Non-FMS active/engaged modes
- White – Armed modes;
- Amber – Alert condition
- Red – Abnormal condition. AOM 9-03-30
What does an amber LIM on the FMA indicate?
The auto throttle is in speed mode and the selected speed target cannot be achieved because the auto throttle has limited N1 rating. AOM 9-03-30
What are the two precision approach capabilities of the airplane?
Either APPR 1 or APPR 2. AOM 9-03-30
When is the autopilot aural alert triggered?
When the auto pilot is disengaged by the pilot or due to a system failure. AOM 9-03-30
How can the autopilot aural alert be cancelled?
By pressing AP/PTY buttons on either side stick. AOM 9-03-30
When will the airplane automatically transition to the half bank mode?
When the aircraft altitude is greater than 25,000 feet during a climb. AOM 9-03-40
Prior to selecting the TO/GA button, what must be set in order to display the takeoff crossbar on the PFD?
The flaps set to 1 or 2, the aircraft weight must be set and the takeoff speeds must be sent in the FMS. AOM 9-03-40
What computed takeoff speed reference is set in T/O mode?
V2 + 15 kts (AEO); in the case of OEI below V2 the speed reference will be set to V2. AOM 9-03-40
What altitudes are associated with the ILS approach check points to try to engage the highest system capability available?
1500 ft RA and 800 ft RA. AOM 9-03-40
What is Emergency Descent Mode (EDM)?
A function than can automatically bring the airplane to a safe altitude in the ultimate scenario of cabin depressurization and pilot incapacitation. AOM 9-03-40
When is EDM enabled?
When the autopilot is engaged and the aircraft is above 25,000 ft. AOM 9-03-40
When is EDM activated?
When EDM is enabled and a depressurization event occurs (a red CABIN ALTITUDE CAS message is displayed) AOM 9-03-40
Note: EDM is triggered specifically by the CABIN ALTITUDE HI CAS message, which can itself be triggered by high cabin altitude OR by setting the oxygen knob to PAX OVRD.
If the autopilot (AP) is engaged, what happens to the auto throttle (AT) when the airspeed is below the top of the LSA white bar +5 kt?
The auto throttle will automatically be engaged and the speed bug will be set to LSA white bar +5kt. AOM 9-03-40
What happens to the Autopilot (AP) when the AOA limit function is activated?
It is disengaged. AOM 9-03-40
What phases of flight is the auto throttle system approved to operate in?
All phases of flight; takeoff, climb, cruise, descent, approach, landing and during OEI operations. AOM 9-03-50
What is the purpose of the HOLD mode of the auto throttle?
To ensure that no undesirable thrust reductions are experienced during the takeoff. AOM 9-03-50
When will the auto throttle (AT) HOLD mode be activated?
From the time the airplane exceeds 60 kts during the takeoff until 400 ft AGL. AOM 9-03-50
What is the minimum autopilot engagement height?
400 ft. AOM 2-56
What is the minimum autopilot use height with Vertical Path Reference?
80 ft. AOM 2-56
What is the minimum autopilot use height without Vertical Path Reference?
180 ft. AOM 2-56
When planning to land with the auto throttle engaged, what is the Vref additive and how much is unfactored landing distance multiplied by?
5 kias; 1.1. AOM 2-56
