Thank you! It wasn't exactly this, but I did go check in my axis commands and the TDC slew vertical was showing as always pointed down. This had been bound by default to the little joystick I can manipulate on the throttle with my index finger. I prefer to use four-way buttons for the target designator, so I didn't know this joystick was also bound in the axis commands. It seems to have had a little stickiness and was stuck in the down position so I flicked it and it is working, although it will get stuck a little again. Totally able work around it. I have a Thrustmaster 1600 because I just started about a year ago. Maybe time to get a better throttle now! Thank you so much for your help. Thank you for the idea. It was a sticky index finger joystick I didn't realize was bound to the target designator!

I went to play this morning, and when I turned on BVR in the Su-27 and turned on my radar, the target designator is stuck moving down. I am baffled trying to trouble shoot this. I initially thought it must be some issue with my system because nothing has changed with the game since yesterday. I updated windows and made sure DCS was updated. First I switched to the F-15. The target designator is also stuck always moving down in the F-15 too. I Checked my hotas incase it was broken. Unplugged it. The target designator still always moves down. Checked my keyboard in case that binding was making the problem. I removed ALL bindings from all controls to target designator down. I tried both regular stable and MT versions. Restarted the computer and DCS multiple times, and it is still happening. I can't make sense of it. Has anyone else had this issue?

Good to know. Thank you.

Maybe they changed the mission in the past few years. I don't have any problems crashing, although I always need to increase the brightness on my hud. I had a really hard time with this one at first, especially that one tight turn toward the end. The problem wasn't that I was going too fast. I was going too slow so the aircraft couldn't turn. It needs some speed to make a tight turn. When you start making tighter turns it is really important to increase throttle, which can feel counter-intuitive when it seems like the aircraft it trying to keep tight turns. If I keep it at around 500 kph, it is actually pretty easy. But it took me dozens of attempts to learn this. Also use the rudders to help the aircraft stay low and don't get up too high when pulling back on the stick in a turn.

On this website they switch to the "n" instead of "п" right where they are describing the equations. On the rest of the website explanation, they use П both upper and lower case п. I know the letters look very similar to me as an English speaker, but I thought they were fundamentally different letters. Are the symbols sometimes interchangeable??

I'm going to do some video's on this topic. Here is the first one:

I'm going to making a few videos on this question. Here is the first one:

Here is a video I just made on the clock in the SU-27. https://youtu.be/GkYZ54z-HAc
