I think that getting near-unlimited use of war emergency power settings should only be allowed if
1) we are forced to fly with the same virtual aircraft, damage carrying over between missions and so on: i push it on one sortie, i do it on the next, i keep doing the same thing, it dies on me mid-channel on the 10th sortie or so...happy swimming back to Dover
2) this also applies to multiplayer along with an incentive to keep our aircraft alive (the usual IL2 server conditions where losing all your aircraft means you lose the mission, along with public stat-tracking so that everyone on the server can see who's the points maniac that's depleting all the team's aircraft), instead of having everyone over-boosting and "recycling" them by deliberately crash-landing worn-out airframes
3) it applies to all aircraft, 109s running a constant 1.45 Ata for example
and then we have IL2:1946 all over again
