Runway Remaining
An experimental aviation app estimates how much runway remains during takeoff using consumer GPS, motion sensors, public data, and simplified models.
Field notes
The interface organizes a takeoff sequence around airport and runway selection, aircraft rotation speed, weight and limits, wind entry, sensor access, and runway arming. The stated estimates draw on consumer GPS, motion sensors, public data, and simplified models, with outputs that may include speed, distance, density altitude, ground roll, and an acceleration gate. The site explicitly positions the software as free and experimental rather than certified avionics or an approved performance computer.
