Mountain Worksheet

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
