Ejection charge

[Scott Nokes]

Can anyone tell me if there are reliable ways of triggering the ejection charge other than by Altimeter.
Thank you

There are timers that have been used. Myself, I have never used one. But a search might bring something up that could help you.

Your choices are motor ejection, altimeter or a timer for deployment.

Are you trying to do ground based ejection charge testing ? If so, we just run the wires out of the AV bay vent holes - apply at a distance to battery and hey presto - ejection event.
