I thought I may have lost my bottle for flying R22s this weekend. I have 150 hours PPL(H) and about 12 in the last 28 days. While flying this weekend at 3000 feet I began to feel nervous and recognised the early signs of panic. I chanted out loud the check routine to take my mind off the fact that I could hardly turn the darn thing around to return to the field. Once decended to about 1000 feet it seemed better and a safe return landing was effected. Is that vertigo? I am pondering whether or not to continue.
