The confusion comes from the fact there is/was 2 ACP in the same area.
ACP 2020-055 which has been accepted
ACP 2020-099 which has been refused (for the moment)
The Oban area, Scotland trial is underway, despite claims by some tha the TRA has been refused by the CAA.
It’s NOTAMed active 06/07 March 2021.
A more sensible area than the original one.

Thank you Ibra for these two brilliant links, very interesting read!
It can happen if the practice round (which is hollow) has a manufacturing defect and cracks open once it leaves the cannon muzzle.

Yes true the are are going March3+ otherwise there is no way you can shoot SU27 or Mirage F1 doing Mach2.2 on a dog fight, if such thing exit these days 
Shells will slowdown at some point even when firing to ground targets, F16 will not unless throttling back on F100/F110 behind it…
I doubt gravity or orientation sky/ground matters when speeds are beyond 250kts (or whatever max speed of shells in freefall)
Coriolis and gyro force from earth/shell rotation at Mach3+ speeds is as important as weight ground pull (there are jokes about the Navy being crap in shooting in the Southern Hemisphere but it’s a myth )
It’s also bad if you go faster !
Reading that article, I cannot see how this is possible, if firing at a ground target, other than by firing a burst, and then diving down before levelling off.
The shells are doing mach3 which is about 5x faster than the F16 would have been doing at the time.
Latest in Scotland. Nothing like the consultation proposal, but makes more sense.

What is the muzzle velocity? If it is the speed of sound, the PA28 will fly backwards before it rund out of ammo…
