Auto flight Flashcards
What are the three methods available to disconnect the auto thrust?
Which one will cause a Thrust Lock condition?
Press InstinctiveDisconnect ( preferred)
Thrust lever to idle detent
Press the A/THR pushbutton
Pressing the A/THR pushbutton
What action is required to restore conventional manual thrust control from a “thrust Lock” condition
Moving thrust levers out of the CL or MCT detent
On takeoff what does SRS mean?
V2 + 10
What does the lateral mode RwY means ?
Runway mode is engaged. This mode provides Steering guidance during the takeoff roll, and initial climb (30feet) if a localizer signal is available
During normal takeoff when will the A/ THR become engaged?
When pulling back the thrust levers to CL detent
What’s the difference between the vertical modes CLB and OP CLB?
CLB is managed climb mode- FMGgS programmed altitude constraints are taken into account ; NAV must be engaged
OP CLB is open Climb Mode- FMGS programmed altitude constraint are ignored
Describe ALT crz
Altitude hold ( cruise) mode is engaged and pitch guidance is given to hold cruise altitude
The altitude is permitted to vary +- 50 feet from the selected altitude to minimize thrust variations.
Performance information is based on cruise flight until the decent is initiated.
Whats the difference between the vertical modes Des and Op Des
DES is managed Descent Mode- FMGS programmed altitude are taken into account; NAV must be engaged; pitch guidance is given to acquire and track a vertical profile; if selected speed during descent, the profile is not modified- the aircraft flies the DES profile at the selected speed.
OP DES is open Descent Mode- FMGS programmed altitude constraints are ignored; pitch guidance is given to manintain target airspeed.

S during go around
Slay retraction speed - appears when the flap lever is in position 1 and is the lowest speed to select flaps 0.
What does the green dot represent
The speed corresponding to the beat drag to lift ratio
Green dot also indicate minimum maneuvering speed in the clean configuration.

F represent?

Minimum Maneuvering speed when the flap lever is in position 2 or 3.
