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)
Altitude  Speed 
Through 14,000 feet  230 knots 
Above 14,000 to 20,000 feet MSL  240 knots 
Above 20,000 to 34,000 feet MSL  265 knots 
Above 34,000 feet MSL  0.83M 

FAA Holding Airspeeds (Maximum)
Altitude  Speed 
Through 6,000 feet MSL  200 knots 
6,001 feet MSL through 14,000 feet MSL  230 knots (210 knots Washington D. C. & New York FIRs) 
14,001 feet MSL and above  265 knots

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

.  
above FL250, use VREF 40 + 100 knots to provide adequate buffet
margin.
