Pay by speed
If that's the case, I'm going to re-consider that ANG fighter slot!
Let's just pay by Mach number and call it a day!
Hey wait, that almost works.
.86-.92 (CX, Gulfstreams, 747) 250K+
.82-.85 (VII, G100?, 737) 150+
.79-.81 (BAe, etc) 100+
.75-.78 (LRJET) 80+
.68-.74 (CE500) 70+
.60-.67 (fast turbo props) 60+
<.60 (KA, CHEY, C425) 40+
Whatcha think? Give or take a mach/10K.
