No, you mechanically change a valve that changes the air intake to air that runs past the exhaust manifold and is therefore heated.
This depends on weight, C.G., temperature and density.
This altitude is usually where the combination of L/D ratio and engine efficiency are maximized.
Live side to oppose the yawing moment.
Only hydraulic gear.
If you pitch up in a Seneca the speed IAS will decrease, because of the constand speed drive (in the propeller hub).
The propellers want to maintain the original RPM. Therefore the blades will go to a more fine blade setting.
Easier for the company in regards to training, maintenance and spare parts as you only use one type of aircraft.
Amount of fuel divided by 24 GPH (gallons of fuel per hour).
Hydraulically driven by 2 electric pumps with a 7 second transit.
