holding pattern exit times
 
Often ATC will clear you to hold and say "adjust speed/timing as required to exit a hold at a particular time".

Interested in any techniques to make this work (particularly in the Airbus).

Thanks in advance.

Put a time marker in the flight plan, adjust the hold speed and leg length as required by rough guessing the hold time, once you enter the pattern wind the speed back or faster to put the time marker over the hold fix to exit on time.

Ie: holding at FL300 @ min speed, 2 min legs will take about 8 mins, 1 min legs will take 6 mins

Enter the hold, check next time over the entry waypoint vs time of entry, that gives you time of 1 pattern, and then adjust accordingly.

Start the stopwatch going over the hold fix, and note how long it is before you need to pass over the fix again. Go outbound until the stopwatch says half that time is up, and turn inbound again. You’ll need to make an educated guess at a wind adjustment, but (at least in Oz) you’re allowed to be up to a minute early. Using a time marker and judicious speed adjustments, it should be possible to be within a few seconds.

You don't need to exit the hold via the holding waypoint.

Let us not overcomplicate things. Just press 'exit hold' at the time they give you and stop holding.

Need a “like” button here. Happens frequently into LHR (or did before you know C… something)

Until they say…”adjust the pattern to cross x at time x”

…which is what I thought the original question was about.
