Visual Approach is a flightpath simulator, training aid and touchdown distance calculator for airliners.
● PAPI indications and vertical profile display are continuously updated for distance.
● Adjustable threshold crossing heights and angles
● Touchdown distance and landing gear position calculator
● Altimeter and temperature errors simulated
● Configurable runway markings and lights
● Either feet or metres for distance, and hPa or inHg for pressure.
● Current aircraft : Boeing 737-800, 747-400, 757-200, 767-300, 777-200, 777-300, 787-9 / Airbus A320, A330-300, A340-300, A350-900, A380.
Visual approach guidance indications are tailored to provide safe gear clearance for the most critical traffic at each airport. Differing pilot eye-heights and landing gear positions lead to variations on how these appear and what they mean to other aircraft, so that at a major airport designed for large jets, a small aircraft will appear low with reference to the precision approach path indicators when on the correct slope.
This app allows you to vary the aircraft flight path and the position of the PAPIs by way of Threshold Crossing Height and Slope Angle, and displays PAPI indications, flight deck forward views, aircraft vertical profile, gear position and touchdown distance. Hot and cold weather altimeter errors are also applied to the aircrafts approach profile, so you can see the effects of these at airports youre familiar with. The height display shows AAL, AMSL, eye height and radio altimeter (landing gear) height. The distance display can reference ILS glide slope position or distance from the threshold in nautical miles, meters or feet. You can configure the type and position of runway markings and the lighting set-up to simulate a particular runway. New in version 1.4, the effect of rounding (or errors) in altimeter settings can be demonstrated.
This apps been put together by an airline pilot and is useful for anyone whos changing types or is interested in learning a little more about the factors influencing approach path indications, as well as those beginning their training in aviation or simply curious about these things.
