Spitfire - Should my RPM be linked to my throttles?

[Nic727]

Hi,

I use different control for my throttles and my RPM, but autopilot seems to use something like 50% throttles = 50% RPM, 85% throttles = 85% RPM, etc.

Should I do that? Should I use the same control for the two?

 

Thank you?

No, you don't need to change the prop setting that much  One for takeoff, one for cruise, and one for combat.  The throttle is getting changed more often, especially in combat or landing approach.

The Spit, except the early Mk1 (which were all converted afterwards) had constant speed propeller. By aug 1940 almost all Spits had CSP. This means that in normal operating situations, this including air combat maneuvers, you just had to operate the throttle, and the automatic governor adjusted the pitch as to mantain this constant optimal speed.

In some situations you can adjust the propeller rpm manually, actually you adjust the pitch, like in a 109, for optimizing acceleration, or fuel consumption.

That being the rpm lever. But normally that is throttle linked, the pitch adjusted automatically,  as to mantain....constant speed propeller. Something the IAR, for example, never had. 😞 Or the Macchi had this only for throttle above 1/3.

Late model MKIX and above had a mechanical catch that could be connected to the throttle and the prop lever, so then RPM and boost were linked. You could use it this way or the traditional way.
