Design Principles for Commercial Transport Aircraft: A Pilot's Perspective

Commercial transport aircraft will, for the foreseeable future, require highly skilled human pilots. This requirement is based on broad legal, fiscal, and physiological precedents mandated in the form of Federal Aviation Regulations. The commercial pilot's goal is, and always has been, the safe operation and completion of the planned flight. The pilot's role is to utilize any or all of the resources available to achieve this goal as effectively and efficiently as possible. To achieve the goal of safe flight, the pilot requires a vast set of tools and resources. Aviation system complexity, operating costs, political and economic pressures, public interest, and pilot capabilities all demand nothing less than optimized system design solutions. Aircraft design must be based on clear, concise principles developed from, and centered upon, the requirements and capabilities of the pilot. Aviation system design must be centered upon the pilot-air traffic controller team.

The Advantage of Flightpath-Oriented Situation Displays During Microburst Encounters

No adequate method presently exists for commercial flight crews to reliably predict or detect the presence of microburst activity prior to encountering the disturbance itself. While most shears do not exceed the performance capabilities of the aircraft, because of inadequate instrumentation they may exceed the performance capabilities of the crew. An integrated instrument display would enable a pilot to rapidly detect the onset of a shear and provide optimum guidance to fly the airplane to the very limit of its performance envelope thereafter. Such a display must provide information concerning either airspeed or angle of attack as well as altitude above terrain. We believe the availability of such an optimum flightpath display would have prevented many of the catastrophic microburst-induced windshear accidents. Until such information is provided, windshear accidents will continue to occur.
