- Chapter 11: Helicopter Emergencies and Hazards › Dynamic Rollover
Dynamic Rollover A helicopter is susceptible to a lateral rolling tendency, called dynamic rollover, when it is in contact with the surface during takeoffs or landings. For dynamic rollover to occur, some factor must first cause the helicopter to roll ... pivot around a skid or landing gear wheel, until its critical rollover angle is reached. The angle at which dynamic rollover occurs will vary based on helicopter type. Then, beyond this point, main rotor thrust continues the roll and recovery…

skid or wheel on the ground, the helicopter can roll over on its side. Precautions To help avoid dynamic rollover: 1. Always practice hovering autorotations into the wind, and be wary when the wind is gusty or greater than…
- Chapter 11: Helicopter Emergencies and Hazards › Dynamic Rollover › Critical Conditions
Critical Conditions Certain conditions reduce the critical rollover angle, thus increasing the possibility for dynamic rollover and reducing the chance for recovery. The rate of rolling motion is also a consideration because, as the roll rate increases, there…
- Chapter 11: Helicopter Emergencies and Hazards › Dynamic Rollover › Normal Takeoffs and Landings
Normal Takeoffs and Landings Dynamic rollover is possible even during normal takeoffs and landings on relatively level ground, if one wheel or skid is on the ground and thrust (lift) is approximately equal to the weight of the helicopter…
