## Helicopter Weight and Balance Control

Weight and balance considerations of a helicopter are similar to those of an airplane, except they are far more critical, and the center of gravity (CG) range is much more…

Comments Off on Helicopter Weight and Balance Control

Consider the helicopter in Figure 1. The first leg of the flight consumes 26 gallons of fuel, and at the end of this leg, the passenger deplanes. Is the helicopter…

## Determining the Loaded CG of a Helicopter

The empty weight and empty weight center of gravity (EWCG) of a helicopter are determined in the same way as for an airplane. See section, Single-Engine Aircraft Weight and Balance…

## Ballast | CG Change After a Repair or Alteration

It is possible to load most modern airplanes so the CG shifts outside of the allowable limit. Placards and loading instructions in the weight and balance data inform the pilot…
