January - June 1995
An Informal Review of NTSB General Aviation Accident Reports for the Period of January Through June 1995.  
The following is a summary of incidents from a six month period in 1995 involving stall, insufficient lift for rotation and takeoff, insufficient angle of climb, excessive angle and/or speed of approach, hard landings, and incidents involving gusts or windshear in which pilots could have benefited from LIFT RESERVE Instrumentation.

The AOPA Air Safety Foundation's 1996 Nall Report - Accident Trends and Factors for 1995 - makes the following points:
  • "Takeoff and landing account for about three percent of the time spent in a typical cross-country flight, but 47 percent of all accidents occur during these phases."
  • "Individual responsibility - Responsibilities for providing high levels of safety are on the individual owners, operators, and pilots."
  • "Accidents are caused by a sequence of events or conditions. In most cases, if one of the events or conditions is prevented, the accident will not occur. This explains why many potential accident situations do not become accidents, but one additional ingredient may be enough to create a disaster."
  • "This type of accident [mishaps during takeoff and initial climb in all classes of airplanes] is often the result of lack of awareness of the effects of density altitude on aircraft performance or other omissions in takeoff planning."
  • "Pilot-related causes predominate, accounting for approximately 65 percent of both fatal and total accidents."
  • "The FAA measured task requirements to pilot capabilities, distributed over the duration of a typical flight. Task demands vary throughout the flight, as does pilot capability. Some of the highest task demands exist during the later phases of flight. Pilot capability is often diminished by fatigue and the complacency of a long period of uneventful cruising flight."
  • "Many pilots hibernate until spring winds tax their rusty skills." 
  • The AOPA also states,

    "The present plateau [in accident trends] may indicate a practical bottom level without major changes in technology, training, or other resources." 

    The Lift Reserve Indicator is such a resource enhancing a pilot's skill by providing a continuous and instantaneous display of his aircraft's lift.

    January - June 1995
    (An informal survey)

    Total Number of NTSB reports - GA fixed wing aircraft- 650

    Number accidents in which the Lift Reserve Indicator could have enhanced pilot control- 134

    The following is data from 134 General Aviation accidents from January 1, 1995 through June 30, 1997 in which the Lift Reserve Indicator could have enhanced pilot control.  This data is highlighted by NTSB accident reports.
