Here's an idea for a mod Peter.. how about a mod to have True Airspeed either as a choice, or instead of the IAS on the speed bar? With the speed of these two planes and the high ceilings involved people that already don't seem to get the whole TAS/IAS are really going to be confused.

Not a chance.
If the limit is too low (airbrakes are kicking in at ~ mach 0.92-0.93 which was the safest value I found that gave enough time to react in a steep dive without turning the aircraft into bits) or the formula is wrong, I'm all for correcting it, but I'll not change it to depend on IAS just because someone feels it's wrong.

EDIT: Sorry Jagr I misread your post. If anyone wants to check their TAS just hit Control F1 and enter Wonderwoman view
