About 90D
90D (for Ninety Days) is a simple application to help airline pilots managing their recent experience. Enter your past takeoffs and landings, 90D will compute your deadlines for 1, 2 and 3 takeoffs/landings.
Works only for single type rating. Pilots bi-qualified on Airbus 330/340 (for example) have specific recent experience handling not compatible (yet) with this version...
