I got it working in a Bf109K4 (single seater, non-expert, keen vision 1, awareness 0.5, no radar) on a Pe-8 (range less than 2 km, around 1.2 ish?):
600 meter gun convergence, vertical targetting. I had the revi centered on the pe-8 before dropping nose as I took the screenshot.
Altitude being reported at 2000 seems very, very wrong. You can see both RALT and ALT is 2.9 km for me.
edit: got it working on friendly a.i too. Note the altitude being VERY wrong.
I’m pretty sure it converts azimuth to be relevant to the individual. I rarely use the command, but when someone else uses it I often get a useful bearing and height which reveals a dot. This is solely based on Sim EC experience.
Thats exactly what it does.
Like anything Gaijin adds it’s broken and half baked.
If you have a radar SPAA you can turn on your radar, find a helicopter which is invisible low in the trees, press air alert button, turn off your radar and now continually track the helicopter with ‘air alert’ every 10 seconds, despite not being able to see him. His RWR can easily lead him to believe there is no SPAA looking at him since you have an emission free tracking. When he pops up… he dies.
Another broken mechanic.
Since Gaijin don’t play sim they couldn’t imagine it would be useful for pilots so bind it ONLY to the gunners in bombers, or your cursor position . Since a normal pilot doesn’t have cursor in game the alert only works if your in game cursor (which is hidden and useless) happens to be pointing at a plane in game. Turn on a tracking pod and you can use it… but if you’re in a single player plane, it’s useless.
And as a VR user it’s also doubly broken since, even if you play a bomber, YOUR GUNNERS CAN’T SHOOT FORWARD! So you can ONLY ‘air alert’ planes behind you…
