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.
September–October 1992
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.
May–June 1992
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.
March–April 1992
Implications of the Power Curve on Single-engine Flight in a Twin-engine Helicopter 4 pages. [PDF 27K]
