AirPlanPro: Holding, crosswind [iPhone]

This is the app to directly calculate or practice the mental calculation challenges and flight planing tasks a pilot faces on a daily basis, be prepared for your sim session or school flights. Save money by doing this sessions on the ground, and not in the air or simulator, where you should spend time on refining your skills.
Each section has a to the point explanation on how to do it, and then the practice area where you can do random generated questions. Several sections can be modified to fit your preferences, for the random generation.
Learn how to become really good and fast at the following:
