As Specified in the Procedure
When will the FGCS automatically select half-bank?
FL250
17° bank angle
What is FPA?
- Flight Path Angle is a pilot-selectable pitch attitude (in degrees) of climb or descent
- FGCS adjusts thrust & pitch to mainatin path angle and airspeed
What does the TOGA button do?
- On Ground - Activates T/O guidance crossbars
- In Flight - Activiates Go-around guidance
What do the T/O guidance crossbars do?
- Maintain extended runway centerline
- Maintain pitch guidance according to slat/flap setting
When is the TOGA mode deactivated?
- Another vertical mode is selected
- Autopilot is activated
- TCS button is pressed
When will the FD automatically disply?
- TOGA when TOGA is pressed
- Autopilot activated
- Windshear detection
What is the function of the TCS button?
- Allows manual override of the autopilot
- When released, airplane maintains new altitude(provided ALT was the active vert. mode), but will return previously lateral mode (except ILS, autopilot will recapture the LOC/GS)
What will disengage the autopilot?
- AP button on GP is pushed
- Any manual pitch trim is activated
- Either AP/TRIM DISC button is pushed
- Stick shaker activated
- Flight controls in direct mode
- Aileron or elevator controls disconnected
- Overpowering the yoke
- Internal systems failure
Can the Yaw Damp be deactivated if the autopilot is on?
Yes, it is independent of the autopilot
When will the auto-throttles engage on the ground? in flight?
-Ground - AT TO(GP) is armed & TLA > 50°
In Flight - AT (GP) is armed & airplane > 400ft AGL
Will the auto-throttles compensate for gusty wind conditions?
Yes, up to 5 knots
What will disengage the Auto-throttles?
- AT (TLor GP) is pushed
- TLA difference > 8°
- TL at idle with weight-on-wheels or wheels spinning
- Internal systems failure
What is SPDe? What mode uses SPDe?
- Speed on elevator, thrust is fixed and pitch is adjusted to maintain airspeed (VS changes)
- FLCH uses SPDe for climbs and descents
What is SPDt? What mode uses SPDt?
- Speed on thrust, thrust is adjusted to maintain selected airspeed
- FPA, VS, GS, ALT, ASEL
What are the AT modes?
SPDe, SPDt, TO, GA, HOLD, RETARD (@ 30ft RA)
What does LIM & OVRD mean on the FMA?
- LIM - The selected vertical mode requires more or less engine thrust than is available
- OVRD - The TL are being manually moved (No AP disengagement)
When is CRZ automatically selected
- When +100ft of selected altitude for 90 seconds
- Desired airspeed must be achieved or it will remain in CLB mode
What does the SRC button do?
Selects pilot or co-pilot as the data source for the AFCS
