So, if it can get out to the prefects on OCT1 why does it take two weeks to post it to a public platform? We live in the modern world, cut and paste is quick and easy, most of us can post across multiple social media platforms the same "blurb" in about 5 minutes and get TRA forum, TRF, FB and YORF and others.

This is great news, especially after I have retrofitted 15 rockets with screw switches to accommodate some unwarranted, arbitrary rule. Well done TRA.
The switch issue is settled... However, that still does not allow for a power up of any system that has energetic piro charges attached until at the pad...

And that is an issue why? Not being snarky here at all, trying to understand the problem that needs to be solved here.
There is no problem, just making a statement of fact.. You should not try to imply something that was not said.
It really came across as if you were presenting an issue.

You should try to be less sensitive. I was asking a legitimate question and made it clear it was not intended to be snarky at all.
Why would you power up any system that has pyro charges connected anywhere other than the pad (or possibly a safety table/designated safe area)?
You know, asking for a friend....
Well, now everyone should be clear on what was said.

Care to answer my question?
I'm not going to spend much time explaining this, but powering up in the pits and before arriving at the pad or designated safe area has been an issue in the past; but you knew that.

I always do a test power up prior to heading to the pad in full flight configuration...it's easier to fix an issue at my table with tools than on the pad.I'm not going to spend much time explaining this, but powering up in the pits and before arriving at the pad or designated safe area has been an issue in the past; but you knew that.
I think everybody does at least some powering up of the system, enough to check continuity, at various stages in the prep process. Hopefully well away from anybody else.
Can we assume you do your power-up check befor adding black powder to your piro charge cans. If not, you are an accident waiting to happen.
For the most part all my assy is done at home and the rockets are RTF the day of. All checks are made the night before. I attach my flight card to the rocket and that shows she is ready. Also, now I can use the rubber band to hold my igintor.
With the charges connected?
If anyone is interested...

Yes. All my rockets have a pull pin switch, or a rotary switch to disconnect the power to the Alt. Some, bigger ones, have both.
If your deployment charges contain BP, then you must do your power on checks at the pad or designated safety area and, not in the pit area, etc..

Of course I test with charges...what's the point of testing unless you're replicating flight conditions?
What about applying power to an electronic device designed to take in and safely distribute electricity to pyro events is unsafe? People far too often apply steps and procedures in the name of safety that do nothing except further complicate an already complicated process and never do anything to make the entire event more safe.
Critical thinking...use it.

Not to rehash this whole thread, but the whole point of devices like the Egg Proton and Quantum is that the charges are isolated from power until they are armed at the pad. They can be powered up safely in the pits with charges attached because that’s what they are intended to do. I wouldn’t power up with an igniter inserted in an upper stage motor, but that connection is far easier to make at the pads.
I'm sorry Fred, if you go back and read my post you will see that ALL checks are done the night before, at home. No checks are needed as she is RTF (ready to fly ) when I get to the pad.
I do not care what you think. If you bring a rocket to be RSOed to my table, powered up, you will be told to remove it from the area, to a safe place and power down before your rocket is RSOed and approved for flight.
Sorry then..I must of misread your post....

I'm not saying walk around with a rocket powered up (I don't think anyone would say to do that) - all that movement might trigger the launch logic then you absolutely will have a bad day. Here is my process...
1. Program altimeter
2. Test e-match continuity
3. Prepare pyro charges
4. Verify charge continuity
5. Install altimeter and connect all power and charges
6. Power up altimeter to verify continuity/altimeter self-test
7. Turn off altimeter
8. RSO
9. Off to the pads
No problem. I like to do it this way for one, I get a lot more flights in than if I was prepping each rocket at the field. Also, much easier to fix a problem at home on the bench.
Cameron, if I may ask. What alt's do you fly that need programming before the flight. I do mine once and they are good. Do you switch out alt's between rockets?
