Great Tool for Flight Simulator Lovers! This App is designed to assist Pilots during training in Flight Simulators. The App is divided into 3 (three) screens: 1) FILES - Save the Important Files (such as CHECKLISTS) for your flight so you don’t have to look for them every time. You can add any information you need in any of the four sections (any other files that may be useful to you for quick access during the flight) 2) NAVIGATION - Here is a Map with all the Airports of the World. You can create Routes for your Flight, save important radio frequencies and mark the Airports you have passed. For your convenience, you can save your Routes. 3) COMPASS - A compass will be very necessary to work out situations of forced return to the Departure Airport. Engine problems during takeoff are a typical critical situation in which the pilot must act quickly and accurately. By placing markers on the compass, you create a plan of action for certain important stages of the flight. Train, learn and develop your emergency response skills with this Pilot Assistant!
