E6B Flight Computer CFI Pilot vs Vane

E6B Flight Computer is the essential aviation calculator for student pilots, CFIs, and cockpit professionals. Built for PPL checkrides, cross country planning, and everyday flight operations — all offline, no internet required. AVIATION CALCULATORS 22 precision calculators covering every phase of flight: Wind & Navigation — Wind correction angle, heading & ground speed, crosswind & headwind components, course & distance between coordinates. Speed & Altitude — True airspeed (TAS), calibrated airspeed (CAS), density altitude, pressure altitude, true altitude, and cloud base estimation using ICAO standard atmosphere formulas. Fuel — Fuel required, endurance, point of no return, and equivalent still air distance. Performance — Weight & Balance with interactive CG envelope chart, top of descent, climb/descent gradient, and percent MAC. Time — Leg time, ETA calculator, and time/speed/distance solver. WEIGHT & BALANCE WITH ENVELOPE CHART Add crew, passengers, fuel, and baggage. The app computes total weight, total moment, and CG position — and plots it live on an interactive envelope chart. The tool every CFI recommends. UNIT CONVERSIONS 9 bidirectional converters: Temperature, Distance (NM/SM/KM), Speed (kt/mph/kph), Altitude (ft/m), Pressure (inHg/hPa), Weight (lb/kg), Volume (gal/L), Avgas weight, and Jet-A weight. COCKPIT CLOCKS & TIMERS Three simultaneous clocks — Zulu (UTC), Local, and Home timezone. Countdown timer with alarm, stopwatch with lap times for leg tracking. HOME SCREEN WIDGETS - Zulu Clock widget — always-on UTC time - Density Altitude widget — current conditions at a glance - Quick Converter widget LIVE ACTIVITY Flight timer countdown on your Lock Screen and Dynamic Island — no unlock needed. WORKS COMPLETELY OFFLINE No internet, no account, no server. Every formula runs on-device using pure ICAO Standard Atmosphere calculations.

Vane is a modern glass-cockpit E6B — the classic flight computer, reimagined for the way pilots fly today. Fourteen precise instruments in one fast, beautiful app that works entirely offline, from preflight planning to the cockpit. Every result is built on real aeronautical formulas and shows its work, so you can trust the number and understand it — ideal for student pilots training for the checkride and for working pilots who want the answer in one tap. — 14 PILOT INSTRUMENTS — • Wind Triangle — heading, ground speed and wind correction angle from wind and course • Crosswind — headwind and crosswind components for any runway • Weight & Balance — live CG and envelope check for every load • Nav Log — multi-leg cross-country planning with 48,000 airports built in • METAR & TAF — aviation weather decoded into plain language • Density & Pressure Altitude — your true performance conditions • True Airspeed & Mach — CAS, TAS and Mach from altitude and temperature • Fuel — burn, endurance, range and reserves • Performance — takeoff, landing, climb and glide distances • Heading — true, magnetic and compass with variation and deviation • Holding — entry, timing and hold planning • Top of Descent — when to start down for a smooth arrival • Altitude & Speed — pressure and density altitude at a glance • Conversions — every aviation unit: knots, nm, feet, °C, inHg, hPa and more — BUILT FOR THE COCKPIT — • 100% offline — every airport, formula and table lives on your device, no signal required • Show your work — open any result into clear, step-by-step math • Save calculations and reopen them anytime • 48,000 airports, runways and frequencies bundled in • Magnetic variation built in — no internet lookup — THREE COCKPITS — • Day, night and red night-vision themes to protect your eyes on late flights • Metric or imperial — your units, everywhere • A calm, high-contrast instrument panel designed to read at a glance Vane is made for student pilots, private pilots (PPL), commercial and airline pilots, CFIs and anyone flying VFR or IFR.
