Line Up and Wait
I'll go reg crawling with you any time. I'm well aware of that requirement. Also familiar with the occasional contradictions in the FARs. I'm reminded of a similar incident at CSG. I knew the controller on the scope at the time. We either called him "Blackie" or Sir. He was a retired USAF fighter pilot and had a manner much like SSG Ermie, USMC ret. You know the guy in Full Metal Jacket. The 121st AHC (Soc Trang Tigers) showed up in formation. Lead didn't add "flight of 8" to his call up. All hands dialed in the code. Blackie went bananas. Needed to be hosed down. Lead then called for an IFR break-up. Things then went south. Nobody got hurt tho.If you’re in airspace that requires it, and with operable transponders, then all aircraft should be squawking unless ATC directed (91.215).
Once you’ve contacted ATC, they determine if the wingmen squawk or not. Standard formation (< 1 mile & 100ft vert) , squawk standby to prevent overlap/ ring around. Non standard (>1 mile & 100 ft vert), either all squawk or lead and trail only. Depends on the controller & SOPs.
Vert, You and I have a bunch of hours and we are both ATPs with spotless records. The IFR supplement in the DOD FLIP tells you straight out NOT to have the herd behind you all squawking for just the reasons you stated. Yeah. I know FAA and military procedures are not the same. But that day we passed through KGPT's TRSA, I thought Blackie's son was on the scope. The blue sky just got bluer.
