AUTO-THROTTLE ENGAGEMENT / DISENGAGEMENT
FIGURE 02-22-10-05 AT PUSHBUTTON
Engagement / disengagement of the AT is achieved through depression of the AT
pushbutton on the GP, only when the airplane is flying above 400 ft Radio Altimeter. When
AT is engaged, the ON symbol on the AT pushbutton illuminates in green and a green A/T
symbol displayed at the top left corner of each FMA. When AT is engaged, the AT modes
are displayed in reverse video on the FMA.
AT can also be disengaged by:
-
overriding the throttles (force disconnection),
-
pressing the AT quick disconnect on engine #1 and/or #2 throttles,
-
FADEC malfunction,
-
pushing AT pushbutton on GP.
Whenever the AT is normally disconnected, the A/T symbol on the FMA will turn amber and
flash for 10 seconds. Upon abnormal disengagement (manual override, failure, or FADEC
malfunction) an "AUTO-THROTTLE" aural warning is triggered and the amber A/T symbol
flashes. The warnings stop when one of the AT Quick disconnect buttons is pressed.
NOTE
AP and AT must be disengaged at minimum used height.
