The Private Pilot Course - Ground Portion gives you an insight into what happens on the ground portion of your FAA Private Pilot Practical Test, commonly referred to as the Checkride Oral. We provide more than one hour of video, showing you a realistic enactment of a checkride oral conducted by an FAA designated pilot examiner and a student pilot. This app also includes insights from an examiner and instructor to give you a full understanding of what to expect on your private pilot practical test. Bonus features of this app are a copy of the FAA Airplane Flying Handbook, the Private Pilot PTS, the FAA Risk Management Handbook and the Aeronautical Information Manual (AIM). Also included is a quiz to test your knowledge and calculators for Stall Speed, Load Factor, Maneuvering Speed and Top of Climb calculations. Please check out our companion app, the Private Pilot Course - Flight Portion, that gives you more than two and a half hours of exciting in-flight HD video and detailed animation including an in depth explanation of the takeoffs, landings and maneuvers needed to pass your FAA Private Pilot Practical Test. Both apps together make a perfect package that will make you pass your Checkride with ease. Due to HD video, this App is more than 750MB in size. Please make sure you have enough space on your device. Due to size restrictions, you have to be connected to a WiFi network to download this app.
