GPS arming before going to the launch pad?

[Frederocket]

I feel like this has been answered before on other threads, but I can't see where. It wasn't specifically addressed on the LDRS thread. I use an Eggtimer Quantum pretty regularly. That altimeter checks continuity while it is on but not armed, but it does not arm until commanded by Wifi. Actually, I don't think it will even arm if the altimeter expects continuity on a channel based on your settings and finds no continuity.

For small rockets, I would like to use the following procedure with my Quantum:
In prep area:
Assemble altimeter with charges
Plug in battery and check continuity
Button up AV bay and rocket
Take to RSO table and pad

At pad:
Load rocket on pad
Arm Quantum via Wifi
Connect motor igniter
Launch

Is this acceptable under normal TRA/NAR rules? The altimeter is not armed until the rocket is on the pad. Obviously, the LDRS rules at MDRA were different, and I would respect those if I were at a launch when they were in effect.

Checking the continuity of prepped charges, (i.e., loaded with BP and connected to electronics or not), in the prep area is not proper and is not acceptable, no matter the circumstances or electronics used. It is stupid to do so...
