RNAV/RNP NAVIGATION ELIGIBILITY
AUTOPILOT FUNCTIONS
13.2.1 ALTITUDE CRITICAL MODES (ALT, GS, GP, TO,
GA, FLC)
When the airspeed trend vector (dedicated algorithm) reaches 65 +/- 2 KIAS a
single aural ―AIRSPEED‖ will sound, alerting the pilot to the impending under-
speed condition, which requires pilot action.
If the aircraft decelerates to stall warning and a speed of 65 KIAS is reached, the
lateral and vertical flight director modes will change from active to armed and the
autopilot will provide input causing the aircraft to pitch down and the wings to
level.
The aural ―AIRSPEED‖ alert will sound every five seconds.
If aircraft is unintentionally decelerated to 65 KIAS, a MINSPD annunciation
posts above the airspeed tape on PFD in alternating amber and black text. A red
―UNDERSPEED PROTECT ACTIVE‖ annunciation will appear to the right of
the vertical speed indicator. USP will drive the pitch down until the indicated air-
speed increases above 70 KIAS or stall warning turns off, plus two knots (which-
ever comes first).
When USP disengages, autopilot will cause the aircraft to pitch up until recaptur-
ing the vertical reference (vertical and lateral flight director modes will change
from white armed to green active).
