Plan your descent with precision. Descent Calculator 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. BUILT FOR THE COCKPIT Works on iPhone, iPad, and Apple Watch No internet connection required One-handed operation with large, easy-to-read values Digital Crown support on Apple Watch WHO IS IT FOR? Student pilots learning descent planning. Private pilots flying VFR cross-country. Instrument-rated pilots practicing IFR approaches. Airline pilots looking for a quick FPM reference. Flight instructors teaching energy management. Flight sim enthusiasts using MSFS or X-Plane. FREE VS PREMIUM The free version covers essential descent calculations with preset values for speed, distance, and altitude.

Verdict
The clearest difference is in-app purchases: Winglet Flight Display at none against Descent Calculator's 3. Descent Calculator's advantage is update cadence (fortnightly vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
