correct as-is Dispenser Bypass Behaviour

[Phantom711]

There are 2 things that I find kind of implausible with regards to the behaviour of systems in the Hornet, here is the first one.

The Dispensor switch has 3 positions: OFF-ON-BYPASS

What I find not very plausible is, that when I turn it ON, let it do all its self-tests and then turn it to BYPASS, because....well I come to that later.... But let´s say, I turn it back to ON subsequently, it goes through its selftest again and then remains in STBY mode.

Now why do I find that unplausible?: The bYPASS position is a position beyond the ON position, so I would consider it a submode of it being ON. Apparrently you can release Chaff/Flare, so it must be on somehow.

Why do I find it annoying?: Let´s  think about what the usecase of the BYPASS position might be... There are 2 that come to my mind. The first one is an "items check" during the Fence-in in order to check if C/F dispense correctly. It is kinda´hideous that after that you have to go through all the button presses on the EW page in order to set your desired progarm...let aloe the waiting time for the self-tests. The other use case would probably be training sorties, where you don´t want to dispense that many C/F on every press, but chust want to do it for the purpose of training, but therefor rather more often per sortie.

Do I have proof, that my claim is correct, and switching fom BYPASS to ON should not trigger the self-test and simply return to it´s last state? No. I simply think it would make more sense.

I would think the BYPASS mode is using more the JETTISON logic/mechanism rather than the actual ALE-47.  I assume it's a backup system since CM's are pretty critical.  So I can't imagine you'd ever use it to test function.  And for same reason I doubt the ALE-47 is "on" when using it (again, if it's broken you probably don't want to power it but you may need CM's still.  Also, with a DTC, it's pretty simple to set up whatever program you need for your flight so it really doesn't require doing anything.

I also have no actual knowledge of it, but that's what my logic on it would be.

Ok, that´s probably also a way of looking at it. What triggers me about it, is the fact, that the switch is OFF-ON-BYPASS instead of BYPASS-OFF-ON. See what I mean...?

Anyways, it´s not a big deal...

Forward complaints to mcdonnel douglas on that one.
