A speed for holding is displayed at 1R on the HOLDING
PATTERN page, shown in Figure 6--91. For PILOT
SPD/FF or CURRENT GS/FF, the holding speed displayed
is chosen in accordance with the following priority:
a. Pilot entered value (large characters)
b. Default holding speed from the aircraft database
c. Predicted speed at waypoint
d. 90 kts.

When desired, enter an airspeed. Entering *DELETE*
returns the default holding speed displayed when the page
was accessed.
DETAILS -- The speed command is changed to the holding
speed at an appropriate distance to decelerate the aircraft
by the time the holding fix is reached. The holding speed is
maintained until the holding fix is crossed, when exiting
hold.

Enter leg time (2R) or distance (3R). When a leg time is
entered, the FMS computes the leg distance. When a
distance is entered, time is computed. The FMS
computation of leg time and distance use a ground speed
of 90 kts. Leg time defaults to 1.0 minutes.
