2.3 VERTICAL AND LONGITUDINAL UPPER MODES
2.3.1 General
- In three axes coupled mode (ALT or VS):
. In case of insufficient collective pitch to meet the vertical mode reference,
helicopter speed decreases and should 60 kt being crossed IAS mode
will self-engage shifting the vertical mode to the collective axis.
In case of engine failure, the collective axis is automatically engaged
and the autopilot will maintain the power rating selected by the pilot: OEI
HI, OEI LO or OEI CT.
- When both IAS and a vertical mode are held, or in CR.HT (with or without
IAS engaged) the following priorities apply, if the required power is over
the available power:
. the power is maintained at maximum according to the figure below,
. vertical mode reference is held for airspeeds over Vy,
. below Vy present airspeed is maintained.
- During descent or deceleration, the minimum torque obtained is 2 x 5% in
AEO or 10% in OEI.
