One of my favorite planes the F-4 Phantom. And one of our alpha testers recently casually mentioned that he was an Israeli Air Force F-4 Phantom flight instructor. I’ve been exchanging emails with him about every 30 minutes or so, on average, for 12-hour-long days, for the past 5 days or so. We have been doing DOZENS of changes of EXEs and ACFs to get the F-4 in X-Plane flying PERFECTLY.

So here we go: First off, thanks to this intensive, minimum-sleep, once-in-a-lifetime week, we now have an F-4 flight model that is accurate enough to be used for actual F-4 flight instruction: It flies JUST like the real plane through its’ huge flight envelope, from dirty, low-speed approaches, to high-G maneuvering, to Mach 2.2 travel at FL500, to the ceiling of FL600, with acceleration, deceleration, gliding, all representing the real plane as close as an instructor pilot can tell by flying it.

So here is the thing about the F-4: It has a HUGE speed envelope, going from 150 knots to… 1,500 knots.And a HUGE angle of attack envelope, going from zero to… 25 or 30 degrees AOA without losing control, as that huge delta wing rolls up a giant vortex to maintain low pressure above it, without stalling, up to absurdly-high angles of attack.
