Hurricane mixture

[Blackdog_kt]

The hurricane's throttle handle has a knob that extends to the side, which pulls back the mixture lever when throttling back. This is also why the mixture is reversed and rich is backwards: the aim is to have the mixture go to rich when throttling back to prevent running rough at low throttle settings.

It's similar in the Tiger Moth with its manual mixture and in order to maintain similar controls among all RAF aircraft and not confuse the pilots when converting from one type to another all RAF aircraft, even those with semi-automatic (auto-rich and auto-lean) mixture controls, follow the same reversed system.
