Descent Optimizer

Calculate your ideal descent rate instantly. Precision FPM values for every aircraft from Cessna to Airbus. Apple Watch and iPad supported. Offline ready. Free to start.

Plan your descent with precision.

Descent Optimizer calculates the ideal feet-per-minute (FPM) rate you need to reach your target altitude so you always arrive on profile, stabilized, and ready to land.

HOW IT WORKS Enter your ground speed, distance to go, and altitude difference. The app instantly calculates your required descent rate, accounting for aircraft performance, wind conditions, and deceleration distance.

AIRCRAFT PROFILES Choose from four realistic categories each with tailored approach altitude, level-off time, approach speed, and FPM limits:

Training: Cessna 172, Piper Cherokee, Diamond DA40 Turboprop: King Air, ATR 72, Dash 8 Regional Jet: CRJ 700, Embraer E175, ERJ 145 Airliner: Boeing 737, Airbus A320, 777, A350 WIND CORRECTION Factor in headwind or tailwind components to see how wind affects your required descent rate in real time. The app adjusts effective ground speed and recalculates your FPM automatically.

DECELERATION DISTANCE Flying faster than your approach speed? The app calculates how much distance you need to slow down and subtracts it from your available descent distance just like real flight planning.

GO-AROUND ALERTS If the numbers don't work too close, too fast, or unstable approach the app warns you before you commit. Know when to go around before it's too late.
