In aviation, to be allowed to legally operate an aircraft in commercial air transport or carrying passengers, you need 3 takeoffs and 3 landings in the preceding 90 days on that aircraft type. By entering the dates of your takeoffs and landings, this app gives you an easy to interpret preview of when your next ones are due. With 3in90, you can manage all your relevant aircraft types - separately.
