The time delay that occurs between the actuation of an escape system and the actual initiation of the ejection catapult acceleration to separate the crew from an aircraft is one of the critical factors in the design of escape systems for high-speed low-level HSLL flight conditions. This delay may preclude what could otherwise be a successful escape from certain HSLL profiles. The purpose of this paper is to examine the significance of current operational delay times and describe techniques to minimize the delays. Operational through-the-canopy ejection data are presented to assess the risk of injury incurred in eliminating the delay time altogether. Experimental data from tests with human volunteers are presented to demonstrate the potential for significantly reducing the time required for upper torso retraction. Finally, the implications of available aeromedical evidence are evaluated in the definition of the most promising approaches to minimize the time required for a HSLL escape sequence.
