I was answering DaveBB not you. I should have quoted him to make that clear. I'm confident the Navy is giving you adequate training.  :D

Are you using CNATRA P-1289 for ACM FTI?  I'm wondering if they still use the same illustration for one circle and two circle flow, I found that confusing.

P-1289 Rev 01-16 for BFM and SEM, yeah lol. Don't even get me started on trying to understand these FTIs... I'm trying to make heads or tails of my Strike FTI (Bombing) and every time I read it I feel like I understand less and less... but then I'm a kinesthetic learner.

I'm just getting back into Aces High, and I've gotten into some good fights in the P-47.  I forgot how good the plane was in a rolling scissors.  Anyhow, I've noticed that when I stall the aircraft (an accelerated stall I believe), the nose actually pitches up.  This seems a bit counterintuitive to me.  Why would the nose pitch up in such a manner?
:airplane: I think if you film a straight ahead stall in any confg, i think you will see the aircraft actually slide backwards for just a instant before the nose pitches downward! Film it with a mountain in the background and you can see this effect! I think that is why the nose appears to come up to start with. I think the angle of incidence of the wing has some effect, because as the separation point advances towards the leading edge of the wing, for just an instant, the leading edge still has some lift effect which might account for this! I am not an engineer, just a stick jock who has seen a lot of strange behavior of different aircraft since 1948!
Blue Skies and wind at my back and wish that for all!!!

I just tested offline. Turning left, turning right, in a climb, and in a dive. I found that the majority of the time that I'm hearing the stall horning, I'm holding right rudder.  Then when the aircraft truly stalls, the nose pitches up.  Still not sure what is taking effect.  Its similar to how the 262 will let you over-rotate, but nowhere near as dramatic.

This probably does not effect the stall, more for recovery probably, but did you have CT on or off? Head into the TA sometime with a trainer amd turn your show smoke on and they can probably discribe what forces are causing the nose up tilt or appearance there of (may be the vert stab stalling ouu due to rudder influince cutting off airflow so your tail is falling down and the torque is kicking it "up," but that is just a guess).
