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: CALCULATOR: CROSS/HEADWIND: ● Calculate your crosswind and headwind in an easy way. ● Create profiles for each RWYCC for your flap settings on multiple aircraft. ● See a visual representation of how far above/below you are on your flap limits. EASA ALTERNATE PLANNING MINIMA: ● An easy way of figuring out what alternate planning minima you need to work with. HOLDING ENTRY AND CORRECTION: ● Figure out what entry to fly. ● Calculate how many degrees and how much time to correct in to the wind. ● Supports both VOR Radial and inbound course, Right and Left holdings are also supported. TEMPERATURE CORRECTION: ● Calculate temperature correction for multiple points at once. DESCENT PROFILE: ● Calculate top of descent point and feet per minute. MDR: CROSSWIND: ● Learn 3 different ways of calculating crosswind. ● Select wind speed range. ● Have the questions fade after a selected time frame. ● Toggle visual representation of the crosswind scenario. ● Prevent or allow tailwind conditions. HEADWIND: ● Learn 3 different ways of calculating headwind. ● Select wind speed range. ● Have the questions fade after a selected time frame. ● Toggle visual representation of the headwind scenario. ● Prevent or allow tailwind conditions.
