Turbo Charging
In our basic trainer aircraft, at takeoff you have mixture rich and firewall the throttle, in a complex aircraft, its mixture rich prop fine and firewall the throttle.
Don't try that in a turbo charged aircraft, in my C182TR the throttle was approximately 50 per cent advanced (distance wise) at take off, that's 32" manifold pressure with a measure of turbo assistance on line. Airfield elevation 5000" plus.
In a non turbo aircraft at the same elevation you get about 25" boost.
The throttle had advanced to the firewall by 20,000'. The aircraft was factory fitted with a 4 place oxygen system, that's something else!
Turbo cooling was another issue, it rotates about 20,000rpm at a very high temperature, obviously as it is in the exhaust flow, and does need a few minutes to cool down. It is necessary to keep the engine running as the oil lubrication for the turbo unit is engine driven, and an oil flow has to be maintained through the turbo during the slowing down cycle. 5 minutes was usually allowed after touchdown.
As I said it is the most challenging part of the complex conversion and should not be underestimated. If you do not look after that turbo, things can and do go awfully quiet.
