Aviation Calculator

Aviation Calculator puts everyday flight calculations behind dedicated keys, with the feel of a familiar pocket calculator.

Designed for student and private pilots, it brings wind, navigation, fuel and performance calculations together in one app.

FLIGHT KEYS AT YOUR FINGERTIPS Calculate crosswind and gust components, wind correction, true heading, groundspeed, time en route, fuel requirements and density altitude. Open the function library for 24 aviation formulas, plus a weight-and-balance worksheet and a complete unit converter.

BEYOND THE BASICS Plan a descent, convert climb gradients, explore turn performance, estimate still-air glide range, find a point of no return or equal-time point, and interpolate between chart values.

UNDERSTAND THE RESULT See units beside every input. Load clearly marked examples. Read the formula, source and assumptions for each aviation calculation. Invalid or impossible inputs produce an explanation, and changing inputs clears the previous result.

YOUR PREFERRED UNITS Choose knots or miles per hour, and US gallons or liters in Settings. Flight inputs and results convert automatically; saved calculations remain reusable across unit changes.

YOUR WORK, ON YOUR DEVICE Pin favorite functions, restore entered values and revisit your last 100 aviation calculations. The editable loading worksheet totals weight, moment and center of gravity using the aircraft data you provide.

BUILT FOR iPHONE AND iPAD Use a compact calculator on iPhone or keep the function library alongside your work in a wide iPad window. Calculations work offline during your trial or after unlocking. No developer account, advertising or tracking.
