About

E6B

This app provides a comprehensive suite of aviation calculations for pilots, including weather, preflight planning, in-flight adjustments, and weight and balance computations. It also offers a wide range of unit conversions for aviation-related metrics.

Highlights
  • Weather calculations (pressure/density altitude, crosswind)
  • Preflight planning (airspeed, heading, fuel)
  • In-flight calculations (true airspeed, altitude, groundspeed)
  • Weight and balance with custom aircraft profiles
  • Extensive unit conversions
  • Time math (add/subtract times)

WEATHER • Pressure & Density Altitude — from baro setting, OAT, and field elevation • Crosswind, Headwind & Tailwind — enter wind speed, direction, and runway heading • Cloud Base & Freezing Level — AGL and pressure altitude • Hydroplane Speed PREFLIGHT • Planned True Airspeed — from CAS, pressure altitude, and OAT • Required CAS / Required TAS — reverse-solve airspeed equations • Heading & Groundspeed — full wind triangle solution • Compass Heading — with magnetic variation and compass deviation • Leg Time — solve any one of time, speed, or distance • Fuel Required & Endurance • Planned Mach Number • Time Math — add and subtract times in HH:MM:SS IN-FLIGHT • Actual True Airspeed — from CAS, altitude, and OAT • Actual True Altitude — corrected for non-standard temperature • Groundspeed — from elapsed time and distance • Fuel Per Hour — from fuel used and elapsed time • Distance Flown WEIGHT & BALANCE Build custom aircraft profiles with stations, limits, and CG envelopes. Load passengers, fuel, and cargo — E6B calculates total weight, moment, and CG in real time. Save multiple profiles for different aircraft. CONVERSIONS Bidirectional converters for: NM ↔ SM ↔ km, feet ↔ meters, °C ↔ °F, inHg ↔ mb, lbs ↔ kg, US gallons ↔ liters, HH:MM:SS ↔ decimal hours, Avgas and Jet A weight (gallons or liters to pounds), and minimum climb gradient to percent or degrees.

E6B Flight Computer Calc is a digital E6B for pilots. Every calculation is free, works offline and has a keypad built for the cockpit. FREE • True airspeed, density altitude (with an optional dew point) and true altitude • Wind triangle, find the wind from heading and track, and runway crosswind • Time, speed, distance, fuel, PNR and equal time point • Climb and descent, with the descent rate needed to reach a fix; turn and glide • Weight and balance with load sheet, CG, %MAC and envelope (one aircraft saved free) • Great circle, magnetic and compass, holding entry, cloud base • Conversions, Zulu and local clocks, sun and twilight, flight timer with Live Activity, countdown • Your units: hPa or inHg, kt, km/h or mph, nm or km, °C or °F, litres or gallons • Apple Watch app PRO (optional) • Unlimited METAR and TAF decoding (paste the report) • Unlimited analog E6B wheel and exam mode • Unlimited aircraft profiles and full history • Crosswind and density altitude widgets Weekly, monthly, yearly or pay-once plans. GOOD TO KNOW A planning aid, not for navigation: use the POH/AFM and approved sources. Weather reports are pasted, the app does not download them. Density altitude without a dew point assumes dry air. Terms of Use: https://ghapps1.wordpress.com/terms-condition/ Privacy Policy: https://ghapps1.wordpress.com/privacy-policy/

Verdict

The call

E6B and E6B Flight Computer Calc are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
