Low G in the helicopter can be fatal

If you get light in the seat due to abrupt forward cyclic input or turbulence, it is very important to recover the helicopter with gentle aft cyclic. This will reload the rotor system.

Catastrophic mast bumping can occur in a semi-rigid rotor system if the pilot makes cyclic inputs when it is unloaded. Although not catastrophic, mast bump pounding can occur in a fully articulated rotor system.

The helicopter will roll in the direction of tail rotor thrust when in low G. This may cause a pilot to feel that lateral cyclic is immediately necessary to correct for the roll. It is very important that the pilot resist the urge to correct for the roll and gently reload the rotor system with gentle aft cyclic first. After reloading the rotor system, the pilot can then correct for the roll with lateral cyclic.

To avoid low G, travel at lower speeds in turbulence and never conduct low G push-overs in a helicopter.

Low G in a helicopter can kill you. Although we do not practice this in training, you must commit it to memory and understand it.
