Aviation Calculator AvCalc

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.
