Salute

Immersion is also about FM accuracy, but not to the detriment of that extra chrome which gets people excited.

Accuracy in flight modelling is a Nieuport or Albatros Sesquiplane wing aircraft, which displays the wingflutter they had historically.

Immersion is when that fluttering is the noticeable drumming vibration which shakes the plane. It is also when you report to afternoon briefing, (something which is lacking in IL-2) and your C/O tells you your trusted wingman has been lost due to wing failure.
