Aviation Calculator AvCalc vs E6B Flight Computer + W&B

AvCalc is a focused aviation calculator for pilots, student pilots, instructors, and flight planners who need quick cockpit-style answers without digging through menus. Plan flights, check wind, estimate performance, decode weather, and keep common aviation calculations in one compact app. Calculate: • Time, speed, and distance • Wind correction, heading, and groundspeed • Crosswind and headwind runway components • Fuel required, endurance, range, and burn rate • Pressure altitude, density altitude, ISA deviation, and TAS • Mach, climb, descent, glide, and top of descent values • Cloud base estimates • Aviation unit conversions • UTC time, timers, and flight time math • Navigation coordinates and magnetic variation helpers • Map scale distances • Holding entries and wind correction • Weight and balance with CG and envelope checks • METAR and TAF weather report decoding AvCalc is built for fast, repeatable use: enter the values you know, get clean numeric outputs, copy results, and save recent calculations for later reference. Whether you are preparing a lesson, reviewing a route, checking runway winds, or doing quick performance math before a flight, AvCalc keeps the core aviation calculations close at hand. Always verify calculations against current aircraft documentation, approved flight manuals, official weather sources, and operational procedures. AvCalc is a planning and reference tool and is not a substitute for required flight planning, navigation equipment, or pilot judgment.

E6B combines a flight computer with aircraft weight and balance tools for training and flight planning. FIND YOUR CALCULATOR Search by calculator name, category or input such as TAS.

FREE CALCULATORS • Time, speed and distance • Fuel required for a leg, including reserve • Unit conversions for distance, speed, pressure, temperature and fuel weight PRO — ONE-TIME PURCHASE • Weight and balance with saved aircraft profiles, editable stations, a center-of-gravity envelope, takeoff and landing loads, and PDF export • Pressure, density and cold-corrected altitude • Calibrated and true airspeed, equivalent airspeed, Mach and speed of sound • Wind triangle, unknown wind, crosswind and headwind, heading corrections and off-course correction • Endurance, range, descent, climb, glide, holding entry, turn rate and radius • Performance interpolation, cloud base and freezing level BUILT FOR CLEAR INPUT Enter decimals and negative values with the dedicated calculation keypad. Choose units such as hPa, inHg, feet, metres, kilograms, pounds, litres and gallons. Units appear beside values, and shared inputs carry between relevant calculators. On a wide iPad screen, view results beside the input fields and keypad. Your current input stays intact when the layout changes. Result cards explain the calculation and show its source. Calculations work offline. Purchasing and restoring Pro require a store connection. There are no advertisements or subscriptions. One purchase unlocks the Pro calculators. This app is a training and planning aid. Check your aircraft's POH/AFM and official sources before making flight decisions.
