KC-135 Ground Collision Avoidance System Questionnaire
Abstract
Crew Station Evaluation Facility engineers collected subjective data from a sample of 82 operational SAC crew members. The data provide information needed in the design of the Ground Collision Avoidance System (GCAS) for all KC- 135 aircraft. The GCAS is designed to alert aircrews of an impending ground impact, should current flight conditions/aircraft configuration remain unchanged. This study found that KC-135 aircrews would prefer a multi-faceted, bimodal GCAS warning system. This should consist of a light/ tone or light/voice warning. The light nomenclature, altitude, and the voice message, pullup were the most preferred warning messages. The GCAS warning should be present for as long as the warning conditions exist or until the pilot activates a GCAS system reset switch. The GCAS should begin coverage from 200 feet (AGL) and remain active until 5000 feet (AGL). It should cover roll angles from zero degrees to a minimum upper limit of 45 degrees. Subject data and comments are discussed in further detail.
