Protective Features
The Autopilot automatically protects the aircraft envelope while the Autopilot is engaged. The
Autopilot will not, however, self-engage to protect the aircraft envelope while flying manually.
The Autopilot provides the following protective features:
1. G LIMIT PROTECTION:
•
Keeps total vertical acceleration of aircraft between 0G and +2G.
•
Overrides all vertical axis control modes.
2. AIRSPEED PROTECTION:
•
Limits the maximum airspeed to: V
NE
- 5%.
•
Limits the minimum airspeed to: V
S0
+ 30%.
•
Overrides all vertical axis modes except G limit.
•
Prevents autopilot from being engaged outside of the minimum and maximum
control speeds.
3. BANK LIMIT PROTECTION:
•
Control inputs will not exceed 35
o
bank angle.
•
Overrides all lateral axis modes.
4. TAKE OFF PROTECTION:
•
Autopilot disengages if engaged when airspeed comes alive (~20 kts) to prevent the
airplane from taking off with the autopilot engaged.
•
This allows the autopilot to be engaged on the ground for test and maintenance.
5. FAIL DOWN FEATURE:
•
Autopilot will fail down to a less complex mode if the current or requested function is
no longer possible. See Table 5 for the corresponding fail down mode for all
Autopilot modes.
•
Prevents Autopilot from disconnecting when data from an external source is lost.
•
When such a fail-down occurs, the autopilot mode flashes and is replaced with the
new mode. A visual and audio cue is generated for such mode changes.
