AVIATION CALCULATORS 22 precision calculators covering every phase of flight: Wind & Navigation — Wind correction angle, heading & ground speed, crosswind & headwind components, course & distance between coordinates. Speed & Altitude — True airspeed (TAS), calibrated airspeed (CAS), density altitude, pressure altitude, true altitude, and cloud base estimation using ICAO standard atmosphere formulas. Fuel — Fuel required, endurance, point of no return, and equivalent still air distance. Performance — Weight & Balance with interactive CG envelope chart, top of descent, climb/descent gradient, and percent MAC. Time — Leg time, ETA calculator, and time/speed/distance solver. WEIGHT & BALANCE WITH ENVELOPE CHART Add crew, passengers, fuel, and baggage. The app computes total weight, total moment, and CG position — and plots it live on an interactive envelope chart. The tool every CFI recommends. UNIT CONVERSIONS 9 bidirectional converters: Temperature, Distance (NM/SM/KM), Speed (kt/mph/kph), Altitude (ft/m), Pressure (inHg/hPa), Weight (lb/kg), Volume (gal/L), Avgas weight, and Jet-A weight.
