Pilots must be provided explanations, predictions, factors of safety and
control for high density altitude environments. Anytime a higher than
standard temperature exists at a departure airport, improper planning
and/or a lack of knowledge may lead to a fatal outcome. Attempting
takeoff without a thorough knowledge and understanding of high density
altitude takeoff parameters are known to be contributing factors in
general aviation takeoff accidents. A critical ethnographic study was
conducted to reveal cultural differences among the general aviation
community, air carrier, and commuter and on demand operators. Takeoff
distance, velocity, and time can be presented as a function of aircraft
weight and provide a practical basis for other reliable information.
Participants provide an unintended and unanticipated zero-rate condition
encountered in an aviation operation. This study expands on
participant's zero-rate concerns with ratio level measurements and
graphs.
