Verify before flight. PilotDesk checks basic input plausibility, but it cannot verify aircraft configuration, limitations, weather accuracy, NOTAMs, runway conditions, or approved performance data.

This calculator is a planning/training aid. Do not use it as a substitute for the aircraft POH/AFM, approved performance data, current charts, regulations, weather products, or instructor/operator procedures.

How to use it

Enter the known values above. PilotDesk recalculates as you type. Results are rounded for quick planning and study use.

For aircraft-specific limitations or performance, always use the current approved source for that exact aircraft and operation.

Method & assumptions

Steady, level no-current wind triangle; wind direction is FROM.

WCA = asin(crosswind / TAS); heading = course + WCA; groundspeed from along-track vector sum.
