I recently had an instructor ask me if I would do a flight review for them. Their flight review is due at the end of this month. He completed an online flight instructor refresher course with American flyers in November of 2012, but I am not sure if there is a time limit on using the refresher course to satisfy the ground portion of the flight review since it was completed back in nov of 2012. I have been looking at 61.56 and 61.197, and the only time frame that I see is the one about completing the refresher course no more than three months prior to the expiration date. Is there a time frame in which the online firc can be used to satisfy the 1 hour ground for the flight review.
