I’ll run through each point individually…
Bloom better render - the boom renders quite well already, the colours are stepped like that so the pilots in the receive can count soon to ensure good contact is maintained.
Ability to lock on Refueler Heading - completely unrealistic as previously mentioned, we hand fly AAR for safety reasons.
Realistic fuel loss when refueling (Aircraft that’s refueling should lose fuel during AAR.) - what’s the point in losing fuel, when being refuelled? A boom transfers approx 3500lbs a minute, I promise you - no aircraft in the world burns fuel at such a high rate, barring a space shuttle on launch, maybe 😂.
Bloom Drag - it doesnt create enough drag to be noticable. So irrelevant.
