Just rid of the stupid radar, add radar vectoring every minute, give non-liberal views.
Lower shooting distance and liberal angle shooting and we are closer to a sim.
Effective shooting distances against enemy fighters RL where normally 200 yards or less, and 400 or less for 4engine bombers.
Personally my kill range is normally 400-600 as it stands today.
RL - 70% of all shot down planes did not see the enemy
