787-8
If the FMC holding speed is greater than the ICAO or FAA maximum holding
speed, holding may be conducted at flaps 1, using flaps 1 maneuvering speed.
Flaps 1 uses approximately TBD% more fuel than flaps up. Holding speeds in the
FMC provide an optimum holding speed based upon fuel burn and speed
capability, but are never lower than flaps up maneuvering speed.
Maintain clean configuration if holding in turbulence. Clean configuration is also
recommended for holding in icing conditions. However, to comply with speed
restrictions, flaps 1 may be used in icing.
If the holding pattern has not been programmed in the FMC, the initial outbound
leg should be flown for 1 minute or 1 1/2 minutes as required by altitude. Timing
for subsequent outbound legs should be adjusted as necessary to achieve proper
inbound leg timing.
In extreme wind conditions or at high holding speeds, the defined holding pattern
protected airspace may be exceeded. However, the holding pattern depicted on the
map display will not exceed the limits.

Holding Airspeeds
Advise ATC if an increase in airspeed is necessary due to turbulence, if unable to
accomplish any part of the holding procedure, or if unable to comply with speeds
listed in the following tables.
ICAO Holding Airspeeds (Maximum)
FAA Holding Airspeeds (Maximum)
Procedure Holding
When a procedure holding pattern is selected from the navigation data base and
the FMC shows PROC HOLD on the legs page, the following is true when the
PROC HOLD is the active leg:
• exiting the holding pattern is automatic; there is no need to select EXIT
HOLD
• if the crew desires to remain in holding a new holding pattern must be
entered.
Holding Airspeeds Not Available from the FMC
If holding speed is not available from the FMC, refer to the PI section of the 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
777-200, 777-300
• above FL250, use VREF 30 + 100 knots to provide adequate buffet
margin.
Altitude Speed
