Jeff; small correction- 190 IAS is aerodynamically equal to 190 TAS @ standard conditions. Your pitot reacts to the dynamic pressure of impacting air molecules, independent of density altitude, just like your flight surfaces will, so flight testing to 215 IAS has been demonstrated without flutter. Congrats. Peter
I routinely descend from 12,500' to 7000' for landing with the ASI showing 190 mph IAS, which is roughly 220 mph TAS at those altitudes.
