Roll Rate: the rate at which the plane rolls on its z-axis to either starboard or port side by the pilot moving the joystick to the corresponding side - right?

Well, I find this simple explaination confusing. I have just bought Ospreys 'Typhoon and Tempest Aces of WWII' and I was reading about the Tempest. It said:
'In roll rate the Tempest could not compare with the FW 190, and was also inferior to the Mustang and the Spitfire, although the situation was reversed wih the latter at speeds above 350mph. Below this speed, the Tempest was roughly equal to the Bf109, but above it the German fighter could be lost by making a quick change of bank and direction'.

??? How can the speed of being able to roll your plane help in a combat situation? Yes, you can roll over and do an S-Turn or Barrel Roll but how does this speed really help? I just don't understand this defensive manoeuver otherwise.

Answers on a postcardâ...

You see, as the speed increases, it gets harder and harder to maneuver the plane, i e move rudder and stick. The faster you go, the less maneuverable your plane gets becuase the increased air flow over the control surfaces inhibits their movement. Unless you're amazingly strong, ofcourse.

Now, different planes react differently to this - for instance P-51 could not outmaneuver a Bf 109 at low speeds but was superior at high speeds. Probably the same applies to the Tempest.

I should warn you, though - I've just quit smoking and cannot take full responsibility for what I just wrote http://ubbxforums.ubi.com/infopop/emoticons/icon_biggrin.gif

With the Tempest it was designed with high speed in mind and like with the FW190 a roll and dive is a good defensive manouver. Given the Tempest's roll at high speed is good its probably a worthy evasion tactic vs BF109's.

Speed of roll can change your turn direction, In the case of the FW190 (and I suspect the Tempest at high speed) it hasn't got the greatest turn but a very good roll. If the plane following you has a poor roll but an excellent turn (like a spitfire for instance) you can roll and change direction of your turn quickly. Then you can reverse the roll again and turn again in a different direction. All this time the plane with the slower roll behind you is trying to match this change in horizontal direction but can't even though it might have a better turning circle. Just be careful not to draw your turn across guns of the plane behind you, even though its desperatly trying to match your change in direction it could still get a few rounds off.
