Aircraft Performance Explanation for Takeoff from a High Altitude Airport

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.
