So, I've finally noticed that the afterburning engine in this game...the BFE150...has unrealistic nozzle scheduling. Yes, the nozzle does close on AB engines when advancing the throttle (think garden hose effect), but, typically, only until the AB lights. At that point, there's so much excess thrust the garden hose effect isn't needed, but the engines will overtemp unless the nozzles open again (think melted turbine blades--bad!). When taking off in the T-38, we checked to make sure (among other things) that we had "two swings" within 5 seconds, meaning the nozzle indicator needles swinging to indicate the nozzles opening as the AB engaged. Otherwise, you aborted the takeoff. It's a small thing and I'm not sure if it's an easy fix, but recommend changing the nozzle scheduling to initially close, then reopen above 80 or 90% throttle position, which though not exactly how that works in real life, would be a better visual simulation of what actually occurs.
