Kingair C90 Prop Governor
The C90 has 3 governors.
1. Normal governor
2. Over-speed governor
3. Fuel topping governor.
Its does seem to have a lot of equipment for such a simple device.
Why is the over-speed governor required, shouldn't the normal governor be able to do the task.
In the latest turbo props that have an electronic engine management system, is the mechanical fuel topping governor replaced by software?
