Calculate outbound holding leg timing, inbound timing correction, and standard-rate turn estimates. This free aviation calculator helps pilots with instrument holding pattern planning and IFR training.
Enter the desired inbound leg time and the actual inbound leg time to estimate the outbound timing adjustment. You can also enter groundspeed to estimate standard-rate turn timing and turn distance awareness.
This calculator helps estimate outbound timing corrections to keep the inbound leg near the desired published time.
A holding calculator helps pilots estimate how to adjust the outbound leg in a holding pattern so the inbound leg stays close to the desired time.
In instrument flying, wind often changes how long the inbound leg takes. By measuring the actual inbound time and comparing it to the desired time, pilots can make practical outbound timing adjustments on later circuits.
In general, the inbound leg is 1 minute at or below 14,000 feet MSL and 1.5 minutes above 14,000 feet MSL, unless otherwise published.
The goal is to arrive over the fix with the correct inbound leg time, so pilots usually adjust the outbound leg to compensate for wind.
About 60 seconds, because a standard-rate turn is 3 degrees per second.
