Low Altitude Sight-seeing Flight Ends in Sudden Descent and Death 4 pages. [PDF 31K]
When the low time pilot elected to make a low-altitude turn near a steep glacier face, there was little time or room to maneuver when an emergency situation developed.
Reports Question Engine Failure Safety Margins at U.S. Heliports 6 pages. [PDF 33K]
A survey of helicopter operational data and interviews with pilots suggest that protected airspace at heliports should be modified to better accommodate multi-engine helicopter performance.
Strengths and Weaknesses of Professional Helicopter Pilots Observed During Simulator Training 4 pages. [PDF 23K]
Sophisticated simulators offer dynamic environments where even experienced pilots can hone their skills.
Low Rotor RPM Threatens Safe Helicopter Flight 4 pages. [PDF 98K]
Maintaining proper rotating speed of main rotor blades is a basic flying skill which, if allowed to deteriorate, can affect the safety of flight, especially in light piston-powered helicopters.
Implications of the Power Curve on Single-engine Flight in a Twin-engine Helicopter 4 pages. [PDF 27K]
Flight with one engine inoperative in most two-engine civil rotorcraft is possible only within a narrow airspeed range. Knowledge of those limits prepare the pilot for an unexpected engine failure.
Operating Safely at Airports — Pointers for Pilots and Safety Managers 4 pages. [PDF 24K]
Helicopter pilots share a unique responsibility, not only to develop safety awareness, but to educate airport officials and safety managers on helicopter operations, and to actively promote dissemination of safe practices.
