Spit/109 sea level speed comparisons in 1.08 beta patch

[Crumpp]

I believe your bottom line re a faster aircraft always outturning a slower one to be wrong.

An aircraft at Vmax has zero excess power.

So, the slower airplane has zeo excess power at its top level speed while the faster still has excess power to maneuver.

Understand?

[Crumpp]

For example, the ROC reads around 65+ fpm while sitting still on the runway!

Have you sat in the cockpit of many real airplanes?

Emm we have this chart from RAE



It clearly shows that the Spitfire MK I has better sustained turn performance throughout the speed range than the Bf109E3. It also shows Max sustained G of the Spit as 3G whilst the max sustained G of the BF109E3 is about 2.3G. With the Spit I weighing 6000lbs and the 109E3 weighing 5600lb.

We then have this chart



Which shows the BF109E3 having a better sustained turn performance than the Spifire MKI throughout the speed range. This chart shows (at Take off weight nonetheless) the Spitfire max sustained G of 3.2 g and the BF109E3 max sustained G of 3.25g

Whose chart do you believe RAE or this other thing ?

Well Ivan I would believe the chart made by a practicing aeronautical engineer over a theoretical aeronautical engineer.
