Start reducing to holding airspeed 3 minutes before arrival time at the holding fix so that the airplane crosses the fix, initially, at or below the maximum holding airspeed.

If holding speed is not available from FMC then refer to QRH. Recommended holding speeds can be approximated by using the following guidance until more accurate speeds are obtained from the QRH:

- Flaps up maneuvering speed approximates minimum fuel burn speed and may be used at low altitudes (flaps 1 uses approx. 10% more fuel than flaps up)

- Above FL 250, use VREF 40 + 100 knots to provide adequate buffet margin.


When a procedure holding pattern is selected from the navigation database and the FMC shows PROC HOLD on the legs page, the following is true when PROC HOLD is the active leg:

- Exiting the holding pattern is automatic; there is no need to select exit hold

- To remain in holding a new holding pattern must be entered
