Abstract
A method for diagnosing aircraft airbag initiators in air bag systems includes: providing a diagnostic circuit per aircraft seat, the diagnostic circuit being in a normally off condition and enabled by a user activation; providing a power supply independent of aircraft power; providing a momentary switch; providing a visual indicator; receiving a signal indicating user activation of the momentary switch; and responsive to receiving the signal: completing a circuit, regulating a current into the diagnostic circuit to prevent a squib from firing during diagnostic evaluation; detecting a voltage; and providing feedback to the user.
