Looking at Figure 2-15 the dashed AV-8B line on Mach side 8deg in AUTO corresponds to ~0.825 or 500KCAS. I'm pretty sure I was nowhere near that fast. This was all done a while ago, pre 2.7. I'll retest and see what's what. I was loaded with Gun, TPOD, 10x LJDAM, 2xSidearm. I was HEAVY!
Thanks for pointing me to the NATOPS, I forgot I even had one.
