Kurt, you may be correct, as it was about 12 yrs ago, been retired a few
years now.. I believe it was total temp... B-1B

Hi BT,

What were you flying? Most of my time is in the F-111D and the EF-111A.
I've also flown the F-15, C-130, C-141, KC-10, E-3. Did your aircraft
have a skin temperature indicator or a total temperature indicator?
Aircraft component heating is due to Mach compressibility, not skin
friction. I'm confident that your 100F value reflected total
temperature which is based on Mach compressibility.

The "speed of heat" received it's colloquial name because the speed of
sound is based only on the static temperature of the fluid medium, not
on pressure or density as is often mistakenly believed.
