Abstract:

In support of the KC-135 Avionics modernization Program, subjective and performance data were collected in order to provide the Government and contractor engineers with information needed in the design of a Ground Collision Avoidance System GCAS for all CECKC-135 aircraft. The GCAS will serve to alert the crew of an impending ground impact. This decision will be based on data collected from various aircraft sensors e.g., radio altimeter. The GCAS, due to the downward looking nature of the radio altimeter, will not be as effective as a forward looking Terrain Following Radar TFR and would only serve to complement this system. This evaluation was Study 1 of a two-part study. Study 1 was comprised of four phases. Throughout the four phases, concerns and recommendations were forwarded to the System Program Office and to the Cubic Corporation. This resulted in modification of the algorithm prior to the next phase of the evaluation.
