A lot of changes were made to the module, adjusting other areas of the FM made the EM perfs drift towards what we have today.
The FM team acknowledged that now is the right time to take a look at this area of the FM.
We will get into a feedback loop of testing and adjusting with the SMEs and regarding what available data we have.
It may not be perfectly accurate to the curves you cited though, as they do not represent the performances of our Harrier version. Our N/A is more aerodynamically refined, more powerful but also more heavy than the early Day Attack from which the quoted curves are coming from.
The aircraft should however get less efficient in turns than it is now.
Cheers,
Alpha
