Quote: How would a pilot remain OCTA in those circumstances ?
How about a rate 1 turn? Hardly difficult.
If you think you end up in the same place after a rate 1 turn, you need to do some remedial BAK.
You will drift downwind at the wind speed. If the wind is 30 knots, a rate 1 turn will take you 1 mile downwind. If the wind was, as suggested, 60+ knots a rate 1 turn will take you at least 2 miles downwind.
I'm not sure how you would even calculate a LSALT in those circumstances, without knowing how long you might have to wait.
