Throwing some light on rates of turn

The Spit 1a is faster than the 109 above ~6000 meters.

Apologies for posting this in the turn rate thread...

That is my original testing data Snapper was quoting. My concern was that Spits don't conform to the B6 stated performance (which is what Banks plotted).

For Spit Ia (offline, 0900 game time) I get:

FTH = 16500 ft
at full throttle, 6.2psi, 2750rpm (rad open) 245 mph IAS
245mph IAS@16500ft = 323mph TAS

At 19500 ft
at full throttle, 4psi, 2750 rpm (rad open), 230mph IAS
230mph IAS@19500ft = 317mph TAS

Max speed drops above sim tested FTH (16500ft) as would be expected. My Spit I is slower at alt than 109s and B6 data. Simple IAS/TAS conversion (2% rule).

rpms>2700 give rapid oil gasket failures during these tests.
