Satellite-based Navigation Promises to Enhance Helicopter Utility in IFR Conditions 6 pages. [PDF 36K]
In only four years, global positioning system (GPS) has gone from the first satellite launch to the approval of several helicopter GPS approaches. GPS will make possible nonprecision approaches to virtually any heliport regardless of the availability of ground-based navigation aids.

The Pilot’s Efforts Determine Simulator Training’s Value 4 pages. [PDF 28K]
Good preparation and an understanding of simulator training fundamentals can boost pilot performance and enhance the overall training.
July–August 1994
U.S. Hospital-based EMS Helicopter Accident Rate Declines Over the Most Recent Seven-year Period 8 pages. [PDF 43K]
Emergency medical service (EMS) helicopter accident rates have significantly improved. Nevertheless, the fatal accident rate for EMS helicopters remains high compared with other turbine-powered helicopters, and adverse weather remains the single greatest hazard.
May–June 1994
Judgment Remains Key in Avoiding Potentially Fatal Weather Encounters 4 pages. [PDF 34K]
Helicopter pilots operating under visual flight rules should carefully consider whether the flight can be conducted safely when weather briefers advise that “VFR flight is not recommended.”
March–April 1994
Improved Aeronautical Decision Making Can Reduce Accidents 6 pages. [PDF 44K]
Poor pilot decision making plays a leading role in causing aircraft accidents. But proper training can reduce pilot judgment errors significantly.
January–February 1994
Analysis of Sikorsky S-76 Helicopter Data Shows Comparatively Low Accident Rate 6 pages. [PDF 40K]
A survey of several independent accident data bases suggests that the aircraft’s twin-turbine design, rigorous training requirements and frequent two-pilot crewing have contributed to its overall safety record.
