[Urgency of an issue of promptness of making decision for evacuation of aircraft].

The goal of the given research was actualization of an issue of promptness of making decision for evacuation of aircraft by the pilot as a method of improvement of the effectiveness of the air staff saving. The aims were review of trends in safety benefits of the air staff in case of evacuation of modern aircrafts and grounding of decision-problem of catapulting. The authors said about importance of training, medical-psychological preparation and entitlement of the air staff to flights.

[Preparation of the flight crew to bailout].

The authors demonstrate that the training of flight personnel to the ejection from an aircraft in distress is a learning system that includes interconnected types of land-based activities: studying the material part of the means of salvation, documentation, regulatory need for ejection and the ejection rule; exercises in the cockpit; training on special simulators; parachute training; demonstration bailout; making available to the flight crew documents the forced ejection of the Air Force to analyze their outcomes.

[Human tolerance of the "side-to-side" impact loads].

Three groups of criteria can be used to describe ultimate tolerance of the "side-to-side" impact loads by test-subject as a pre-shock or pre-traumatic margin of relatively safe exposure. These groups include subjective signs, regulatory (bradycardia, extrasystole, brief respiratory disturbances) and spinal biomechanics deviations. Physiological experiments with 12 essentially healthy young male volunteers showed that ultimate tolerance of 0.

[Effects of preliminary loading on dynamic strength of the spine].

The purpose of this work was to evaluate early and delayed effects of static mechanical loading of the spine on human tolerance to the ejection g-loads. Experiments with spine segments showed that static pre-loading equivalent to aerobatic accelerations of 8-10 units leads to relative strengthening of vertebra with low tolerance of the longitudinal shock load. Effect of aerobatic accelerations of 5, 6, 7, and 8 units on ejection g-load tolerance was theoretically evaluated.
