NOTE
Envelope Protection vs. Envelope Alerting
There is a distinction between Envelope Protection
and Full-time Envelope Alerting. Envelope
Protection will result in active driving of the flight
control surfaces by the autopilot. Full-time
Envelope Alerting will only provide visual and aural
alerting but it is up to the pilot to manually make any
control surface changes.
