Abstract
A system and method for alerting a crew member if his anti-G system is not at the proper pressure during a flight. Flight condition sensors and an anti-G suit pressure sensor input data to a computer controller. The controller selects a pressure for protecting the crew member against blackout based on the input and data stored. The controller generates a signal to change the pressure in the anti-G suit to the selected pressure. The controller monitors the pressure status of the anti-G suit and rate of pressure change over time after the signal is generated. If the anti-G suit does not reach the selected pressure within a selected time, an alarm is provided to the crew member. Early warning, caution or failure alarms are generated if the suit does begin to inflate immediately or if it fails to reach a threshold pressure after a threshold time.
