Flight
Runway Performance Calculator
Estimate the runway length required for takeoff based on aircraft weight, airport elevation, temperature, wind, and surface condition. Critical for pilots operating into short or high-altitude airfields.

Flight
Aircraft Performance Calculator
Produce a rough estimate of an aircraft's range from fuel quantity, cruise altitude, outside air temperature, gross weight, and aircraft category. A back-of-the-envelope sanity check, not a replacement for a flight-planning system.
