VFRAID Plan and study VFR across borders
Study aid only — not an official source. Always verify against current national aviation publications, aircraft documents, weather and NOTAMs before flight.

Mass and balance

Choose an aircraft example and enter crew, passengers, baggage and fuel. Compare take-off, landing and zero-fuel cases in the CG envelope.

Aircraft examples

Aeroplane examples use longitudinal balance. The Robinson R22 Beta II includes lateral balance. Preset empty mass and arm are examples; use your aircraft's weighing report for flight planning.

Performance limits

Runway-distance illustrations omit wind, temperature, surface and slope corrections. Helicopter hover capability is not calculated. Use the aircraft's current flight manual and actual conditions for operational calculations.
