Helicopter Weight & Performance
Performance is where helicopter operations fail most often. Density altitude reduces power available, weight reduces margins, and the difference between HIGE (hover in ground effect) and HOGE (hover out of ground effect) ceiling is operationally critical. This section covers weight & balance calculation, density altitude, hover charts, OEI (one-engine-inoperative) performance for twins, and load factor / G-limits for rotorcraft.
