I know the ARTS manual states that the altimeter should only be armed in the upright firing position. How does the ARTS determine its' baseline position upon arming, and how would arming the altimeter in the horizontal position cause problems after launch?

They have a high gee rating and are very easy to arm. You simply pull off the magnet. I have never had a failure using magnetic switches. The basic reed model with no housing is the most flexible, but the standard model works. One just has to remember to use the normally open terminals since the switch is to remain open while the magnet is present and closed when removed. The only limitation is you can only run 1 amp through them. For higher amperage there are ones available, but they are more expensive. I have found having the reed activate other high gee relays an easy work around. ----- Original Message ----- From: _Tomsrockets at aol.com_ (mailto:Tomsrockets at aol.com) To: _arts at lokiresearch.com_ (mailto:arts at lokiresearch.com) Sent: Sunday, July 26, 2009 7:45 AM Subject: [ARTS] ARTS arming position I am helping out with a project that involves a tall rocket.
