Use this calculator for flight-planning study or a first-pass cross-check when all inputs describe the same aircraft, atmospheric condition, and phase of flight.

Weight (lb)

Aircraft weight.

Power (hp)

Engine power.

Compute the power loading as aircraft weight divided by engine power. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Power loading (lb/hp)

Weight per unit of engine power.

• Do not use a generic calculator in place of the current aircraft flight manual, approved performance data, operating limitations, NOTAMs, weather, or regulations. Real performance changes with configuration, runway condition, altitude, temperature, wind, loading, and technique.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Cross-check the result against the aircraft flight manual or approved planning system, then apply the required safety margins. Keep signed wind, heading, altitude, speed, and fuel conventions explicit.

• Wing Loading Calculator

  Compute the wing loading as aircraft weight divided by wing area.

• Center of Gravity Calculator

  Locate the aircraft center of gravity by dividing total moment by total weight.

• Best Glide Speed Calculator

  Compute the best glide speed for the current weight from a published reference.
