Predictions and guidance (HM)
When a hold is selected, the FMS computes:
− Holding speed,
− Deceleration point to enter in the holding pattern at the correct
holding speed,
Predictions at the holding fix are computed once A/C is entered in the
hold.
Deceleration
If speed and lateral modes are managed,
deceleration point is displayed on ND by SPD change
symbol (magenta).
Passing deceleration point:
On PFD:
− If SPD managed, target speed
becomes green dot,
− If SPD is selected "SET HOLD
SPEED" s-pad msg is
triggered.
On MCDU, IMM EXIT prompt is
displayed right side line of the
HOLD pseudo waypoint, enabling
pilot to cancel or exit hold at any
time.
Note:
HOLD size is based on A/C predicted speed at HOLD entry fix; thus in
case of overspeed the HOLD size can be above the expected size.
