**Conquer the Mountains with Confidence** Mountain Flying Worksheet is the essential tool for pilots operating in high-altitude terrain. Built by pilots, for pilots, this app delivers accurate, POH-based aircraft performance calculations specifically designed for mountain flying operations. **WHY MOUNTAIN FLYING WORKSHEET?** Flying in mountainous terrain demands precision. Thin air, high density altitudes, and challenging terrain leave no room for guesswork. Mountain Flying Worksheet eliminates uncertainty by providing real-time performance data extracted directly from Pilot Operating Handbooks, ensuring your flight planning is based on manufacturer specifications—not rough estimates. **REAL POH DATA** Unlike generic calculators, every calculation uses actual performance tables from official POHs: • Cessna 172S (Skyhawk) • Cessna 182T (Skylane) • Cessna T182T (Turbo Skylane) • Cessna T206H (Turbo Stationair) **KEY FEATURES** **Instant Airport Data** Enter any airport code and instantly retrieve elevation, temperature, and altimeter settings. Auto-fetch eliminates manual lookups and data entry errors. **Comprehensive Performance Calculations** • Rate of Climb (Departure, Enroute, Arrival) • Takeoff Distances (Ground Roll & 50' Obstacle) • Landing Distances (Ground Roll & 50' Obstacle) • Service Ceiling (300 fpm threshold) • Density Altitude & Pressure Altitude • Weight-adjusted performance for actual aircraft loading **Critical V-Speeds** • Vx (Best Angle of Climb) • Vy (Best Rate of Climb) • Va (Maneuvering Speed at actual weight) • Vra (Rough Air Speed) • All speeds calculated for your specific weight **Mountain-Specific Calculations** • Canyon Turn Speeds (with flap settings) • Temperature lapse rate for enroute calculations • Performance warnings for high density altitude • Flap configuration optimization **Professional PDF Reports** Generate compact, card-style PDF reports for your kneeboard or flight bag. All critical data in an easy-to-read format that fits your workflow. **Smart Performance Warnings** Automatic alerts when: • Density altitude exceeds 5,000 feet • Temperature exceeds 30°C (86°F) • Aircraft weight exceeds maximum gross weight • Climb performance falls below safe margins
