In my experience, it is better not to play with tanker settings in regards to altitude and speed - it is better to leave it at default parameters. Leg length can be altered if desired with no consequence. Leaving these as is, I never experience these types of issues.
I’d suggest you try the same again but leave it at default speed and height, see if the issue repeats.
Yes - I know you should be able to set these things to whatever you see fit, but sometimes to computer does know better
Thanks for the advice, Malc!
Yeah, looks like I have to stick with the stock ALT/SPD for now.
I Just wanted to test two tankers could establish tracks at different altitude blocks in same area or not.
Still don’t know whether it could happen IRL operation/exercise, though.
