Today I went to Penn Yan and fired up N73450 (a Cessna 172) and performed a number of takeoffs and landings. Every private pilot who wishes to carry passengers must perform 3 takeoffs and landings to a full stop every 90 days in order to stay current and comply with the FAA regulations. It was a popular thing to do apparently since there were 3 or 4 other aircraft doing the same thing. In all I performed 7 takeoffs and landings, which will keep me current until 11.22.08.
