Aircraft Command In Emergency Situations Aces PDF Download

This technology assessment determined the feasibility of FAA support for development of a computer-based system to supplement crew function during in-flight fire/smoke incidents. The system was designated Aircraft Command in Emergency Situations (ACES). It was limited to fire/smoke incidents in areas other than power-plant or lifting and control surfaces. It would be used in large commercial air transports. Thirteen scenarios of in-flight fire/smoke incidents which had occurred or were likely to occur were written to define the events to which a flight crew might have to respond. The responses to each scenario, based on current practice, were described and presented on a timeline. The development of each incident was described as were the significant operational and environmental features. An analysis of each scenario was then made to identify problems encountered in detection and management of the incident. Separate analyses of current sensor technology, aircraft computer/display technology, and of human factors led to a hypothetical ACES system using smoke/heat sensing with determination of rate and extent of change in both. The postulated ACES was incorporated into the master warning concept with advisory displays forced to the cockpit. The scenarios were reanalyzed using the ACES and results compared to the first scenarios analysis. It was concluded that an ACES is technologically feasible and can be used in and facilitate air crew emergency procedures. Training will be needed but crew workload will not be negatively affected. In almost every incident the ACES concept significantly reduced reaction time and severity. (fr).
