Keith, thanks, and your quote "I think that I can see what you are saying, but again you are
starting with a false assumption. Thrust will not remain constant as temperature increases."
I was considering flat rating here. Based on all comments though, I'll assume my scenario would be
true if thrust was somehow constant with TAS. But it isn't, and the effect is significant
enough that it's effect on my academic scenario is that the reverse is true. I'm done. thanks
Bookworm too and all
