## What is LetzFly Computer?

LetzFly Computer is a pocket-sized pilot's toolkit for aviators and anyone who loves the smell of avgas. Fast, beautiful, offline, and crafted with attention to every detail.

WHAT'S INSIDE

- Whizz Wheel. A fully visual, drag-to-rotate E6B circular slide rule. Time, speed, and distance on one face, density altitude and TAS on the other.
- Weight & Balance. 16 built-in airframes from the Cessna 150 to the Cirrus SR22, with multi-category envelopes (Normal and Utility) drawn side by side. Per-station weights, fuel quantity in gal, L, kg, or lb via fuel-type density, total weight, moment, CG, plus an "after fuel burn" projection. Save custom presets. Export a printable PDF load sheet.
- Crosswind. Top-down runway with thresholds painted at each end, animated wind vector, headwind and crosswind components in real time.
- Density Altitude, True Airspeed, Wind Triangle, Top of Descent, Cloud Base, Fuel Planner. Every classic pilot calculator, polished and consistent.
- Conversions. Length, speed, temperature, pressure, weight, volume, fuel mass. Drag any value to scrub it.
- Apple Watch app. Six elegant conversion canvases (altitude, vertical speed, distance, speed, temperature, pressure). Digital Crown to scrub, tap to flip the active unit.

DESIGNED FOR THE WHOLE WORLD

- Multiple fuel types: Avgas 100LL, Jet A, Mogas, UL94, SAF. Density shown in lb per gal or kg per L depending on your selected unit.
- Pick weight in lb or kg, distance in inches or cm, fuel as gallons, liters, kilograms, or pounds, all independently. No "imperial vs metric" toggle that fights your AFM.
- Fuel price, computed per gallon, liter, kg, or lb using the active density.
- Everything runs offline. No account. No subscription. No ads.

LetzFly Computer was built by pilots, for pilots. If your next preflight feels lighter, we did our job.

Disclaimer: LetzFly Computer is a planning aid, not a primary flight instrument. Always cross-check weight and balance results against the aircraft's current weighing sheet before flight.
