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:
“No Ravens wing can stretch the flight so far
As the torn bandrols of Napoleons war.
Choose then your climate, fix your best abode,
Hell make you deserts and hell bring you blood.
How could you fear a dearth? have not mankind,
Tho slain by millions, millions left behind?
Has not conscription still the power to weild
Her annual faulchion oer the human field?
A faithful harvester!”
—Joel Barlow (17541812)
