Simulation/Ground Testing of Redundant Blue Raven Alts

[DizzyUnicorn]

Hello,

I am working on a 4in Cherokee 98 from Wildman, have installed 2 Blue Ravens in the ebay. Primary BR with main and drogue, secondary or backup BR with main backup and drogue backup. Is there a way to run a simulation or a ground test that tests the main (BR Prim) and main backup (BR Backup), drogue (BR Prim) and drogue backup (BR Backup) across the two altimeters in sequence?

Thanks!

Only way I have is with using a vacuum chamber that your ebay frame & altimeters.
Then you need to control how fast the vacuum increases (gaining altitude) and how fast it is released (descent).

Small Xmas tree bulbs are connected to each output. This provides continuity but then glow when that output is fired.

A vacuum test only checks the baro... it's very difficult to simulate a flight with an accelerometer. The best bet is to confirm that the accelerometer is actually working (there should be some kind of test you can perform), then assume that the firmware will react appropriately to the accelerometer readings.
