Hazards of Helicopter Flight
The U.S. Department of Transportation has published a “Basic Helicopter Handbook”. One of the chapters in it is titled, “Some Hazards of Helicopter Flight'. Ten hazards have been listed to indicate what a typical single rotor helicopter has to deal with. The unique coaxial rotor design either reduces or completely eliminates these hazards. The following list indicates which:
- Settling with power — Reduced
- Retreating blade stall — Reduced
- Medium frequency vibrations — Reduced
- High frequency vibrations — None
- Anti torque system failure in forward flight — Eliminated
- Anti torque system failure while hovering — Eliminated
The reduction and elimination of these hazards are the strong points for the safety of coaxial rotor design.

Famous quotes containing the word flight:
“In all her products, Nature only develops her simplest germs. One would say that it was no great stretch of invention to create birds. The hawk which now takes his flight over the top of the wood was at first, perchance, only a leaf which fluttered in its aisles. From rustling leaves she came in the course of ages to the loftier flight and clear carol of the bird.”
—Henry David Thoreau (1817–1862)
