Mininigma is a complete simulator of an Enigma Machine for your iPhone/iPad/iPod Touch. Basically, Enigma was a cipher machine used by the Germans during World War II for the encryption and decryption of secret messages. It looked like an old typewriter with some extra features. Being fully compatible with the real Enigma means you can also use Mininigma to decode any of the original messages which can be found on Internet. You can also generate a machine configuration based on a keyword or keyphrase. That means you'll only have to share that keyword to send a message!! Mininigma can accurately simulate different types of machines: The Enigma I, M3 and M4, Railway, G-312, or Swiss-K, with some others coming in the future. You can read more about these, as always, on the Wikipedia :) You can actually select between the different machine types and setup them as you would with a real one: choose rotors, configure them, or use a plugboard to switch letters. All at the tip of your finger. Mininigma supports Copy/Paste to allow you to interact with any other application on your device. You can even copy/paste machine configurations in an encryptable string!!

**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
