1.)
On any 2 engine airplane with auto/manual prop pitch, deselecting one engine and switching to manual prop pitch also switches the other engine (this in itself is correct? a limitation of il2?), but enabling auto pitch again only affects the current selected engine, so the unselected engine could quickly become unusable , pretty bad when one engine is damaged , you put it in lower power and control the other one , then switching to manual prop pitch then auto again will most likely kill it.
Planes affected: only bf110 and bf109z come to mind (I lost all overview)
2.)
There still seems to be an issue with using the autopilot for your own plane and AI airplanes (I reported this 2002 directly to oleg and he blamed dinput, but now so many parts of my system have changed , nothing is the same , only the bug!), so maybe someone from AI coding can finally look at this:
Create a quick mission with maximum number of airplanes, preferably ones that will drop flaps while turn and burning (some bf109 and or yaks will do), now enable autopilot for one second, after disabling it , drop flaps 1 notch (combat), try not to get shot , simply fly some manoeuvres around all the AI and let them fight.
At some point you will notice that your plane will probably yank around (while pulling a constant turn) and/or you flaps will retract automagically (no , not f4f style
), one time in the campaign my flaps retracted while landing , very funny
I suspect some commands override your own control , this happens only if there are many AI , or the effect is more pronounced / more frequent, it maybe happen synchronously while another plane retracts flaps, but I couldn't be exactly sure watching the tracks.
This also happens when using the black screen skip autopilot 1 time in campaign with many AI planes in the mission as it uses autopilot and time compression.
(track shows simple pre combat , I enable/disable the autopilot and drop flaps 1 notch , as soon as AI call out enemy planes they retract, no axis mapping for flaps and no hud message for retracted flaps!)
