Standard limitations for Speed, Rate of turn and Timing (Holding)

Enter and fly holding pattern at or below given (Standard) IAS.
Non-standard (i.e. lower) maximum holding speeds are published on the relevant charts.
The levels tabulated represent ’altitudes’ or corresponding ’flight levels’ depending upon the altimeter setting in use.
Advise ATC if assigned speed is conflicting with:
– Prescribed maximum.
– Minimum safe airspeed for any particular operation.
A limiting DME distance or VOR radial overrides an outbound timing.

ICAO PANS-OPS

Altitudes (ft) Normal
conditions
Turbulence
conditions
Still air
outbound timing
Above 34.000 M 0.83 M 0.83 1 1⁄2 min
Above 20.000 to 34.000 (inclusive) 265 kt with ATC clearance: 280 kt or M 0.8 (whichever is lower) 1 1⁄2 min
Above 14.000 to 20.000 (inclusive) 240 kt with ATC clearance: 280 kt or M 0.8 (whichever is lower) 1 1⁄2 min
Up to 14.000 (inclusive) 230 kt * with ATC clearance: 280 kt or M 0.8 (whichever is lower) 1 min

* 170 kt for holdings limited to CAT A/B aircraft only.

All turns are to be made at a bank angle of 25 or at a rate of 3 per second, whichever requires the lesser bank.
Outbound timing begins over or abeam the fix whichever occurs later. If the abeam position cannot be determined, start timing when turn to outbound is completed.
Make allowance for known wind by applying corrections both to heading and timing during entry and while flying in the holding pattern.
