Whiz: Aviation Calculator

Whiz is a digital E6B flight computer for pilots of every level — from your first solo to ATPL. 169 calculations across 22 modules, 100% offline, in one fast, distraction-free app.

WHAT YOU CAN COMPUTE
• Airspeeds & atmosphere: TAS, CAS/EAS, Mach, density altitude, pressure altitude, ISA deviation
• Wind: full wind triangle, heading & ground speed, crosswind/headwind components, WCA
• Time-speed-distance, ETE/ETA, and fuel planning with reserves
• Weight & Balance with an interactive CG envelope
• Descent & climb: top of descent, rate of descent, gradients, the 3:1 rule
• Safety tools most calculators skip: engine-out glide ring, V-speeds by weight, and a crosswind GO / NO-GO check that flags the gust against your POH limit
• IFR & pro: runway performance, METAR/TAF decode, holding entries, cold-weather altimetry, oxygen, RNAV/RNP, airline-grade W&B, and more
• Every aviation unit conversion

WHY PILOTS LIKE IT
• Works fully offline — perfect for the cockpit with no signal
• Simple vs Precise mode: cockpit rules of thumb or the exact ISA/geodesic model
• Configurable by jurisdiction (FAA, EASA, ICAO) and by experience level
• Save aircraft profiles to prefill W&B and go/no-go
• A "How is it calculated?" view that teaches the formula — great for students

Whiz is a computation aid. It does not replace your aircraft's POH/AFM, official charts, current regulations, or operator-required calculations. The pilot in command is always responsible for verifying every figure.
