Acceleration comparisons

[IceFire]

Probably a good idea to point out that context is extremely important. As these acceleration tests were all done at the same altitude. Some aircraft will be better and others worse at this altitude... nothing stays the same across the range. It's not one acceleration level that extends from 0 to 10,000 meters.

You have to know your plane. I know that the Tempest V between 3000 and 4000 meters is less capable against the FW190D-9 (which I consider to be its chief rival) as the stage 1 supercharger starts to run out of steam and you're just about to switch to the stage 2. Depending on the D-9 model year... this is the worst altitude to fight at. Take it lower or higher and the Tempest is faster and more able. Context!
