unfortunately, no sim is ever going to model a razor back with a paddle blade prop pulling 72" preassure. Now, that's a monster for you.

Hi Suntracker,

>310ias at 30,000 feet is 496mph. Pretty fast!

Hm, that calculator apparently uses a rule of thumb to calculate true air speed.

According to my calculation, 310 mph IAS at 30000 feet is 506 mph TAS, or Mach 0.75.

That's neglecting both calibration and compressibility error - I'd expect the true air speed to have been considerably lower than Mach 0.75 at that IAS reading.

Hi Bozon,

Get X-Plane and model your own :-) No guns in that simulation, though.

Why don't we see if Nomde could talk HT into modelling this and the other feild mods that were the rule, but make them perked rides?
