Salute!

Great EM diagram, and have been wondering about that for a long time but too lazy to run it down.

In short, too many here focused on 10 or 20 knots and 2 tenths of a gee.

The EM diagram for the Viper shows why it could wax most other planes with even an average pilot that used the excess energy to go vertical rather than pull a lotta gees at a high AoA. Look at the excess energy at 6 or 7 gees and 0.8 M or so.

Secondly, the limiter was not a rate doofer, but approx 9 gees until 15 deg AoA, then almost linear to 29 deg AoA and one gee. Later sfwe may have cranked in some roll rates and such, but not turn rate, Don't have time to link a good diagram, but it is a high school plot. Our rate was a function of the equations I show below.

Also do your own charts using a very simple approximation that gives rough numbers within a few percent of the real world ones using calculus and allowing for bank angle and the phase of the moon. So disregarding bank angle, use these simple equations to get radius and gee and rate,

r=vsquared/a

omega=v/r or simply, v=r*omega

Ypou will get very close to official flight test numbers and within the margin of error for an average pilot trying to achieve exactly 387 knots versus 400 when he yanks.
