Independent Altitude Monitoring Alert Method and Modes Study.

摘要

Several studies have been performed to investigate the effectiveness of and develop independent altitude monitoring (IAM) systems. These studies noted that all IAM system concepts featured the common problem that IAM systems applications may be futile if pilot attention and comprehension of the IAM alert is not assured. This contract was issued to study that problem. The objectives of this study were to define an operational IAM alerting philosophy, develop candidate concepts, demonstrate and refine selected candidates, and develop implementation schemes. The output includes a summary of the alert philosophies used in current aircraft and IAM systems, a data base of currently used alert characteristics including stimuli response characteristics, a recommended IAM alert philosophy for each of four categories of aircraft, and guidelines for developing (or completing development) and implementing IAM alert systems. Basic alerting system concepts were developed for each category of aircraft. Implementation feasibility was evaluated for each concept; implementation recommendations are made.
