Abstract : The report presents the results of an in-house test program to establish design criteria for crew stations as related to crewmember egress from a single place pilot's station in a weightless environment. The objectives were to investigate the egress problems associated with the panel layout of a minimum volume crew station and to establish optimum location of an overhead hatch for crewmembers wearing regular flight suits during an emergency egress condition. A simulated single place crew station was designed and fabricated in-house and mounted in the Aeronautical Systems Division's zero gravity aircraft. An overhead hatch bulkhead was designed to be adjustable which allowed the egress task to be performed at different locations from the seat reference point (SRP). Three hatch locations were used. In the first series of tests the hatch opened outward from the crew station and was tested at the three locations; in the second series the hatch was tested at the maximum distance from the SRP but opened inward. Three times were recorded for the egress task; reaction time, egress to the hatch, and egress through the hatch. Three subjects were used to give six replications for each hatch location. The data were statistically analyzed using F ratio and t tests and the results indicated that egress through an inward opening hatch took 1 1/2 to 2 times longer than to egress through the hatch that opened outward. The time required to egress to the hatch proved to be what would be expected; the time increased as the hatch distance to the SRP increased. (Author)
