What three valves does the manifold valve contain?
Metering - mixture - distrabution.
What does the FADEC control?
Fuel injection.
When would we have the fuel pumps switched on in a piston aircraft?
During critical phases of flight.
What two ways can you cooldown an engine?
Air and liquid.
What psi do you need to raise the boiling point of water to 140 degrees?
15psi.
What does a A stuck oil pressure relief valve do to the oil pressure?
Increases it.
The safest method of priming a piston engine for starting is injection of fuel in the blank blank ports.
Cylinder intake
The function of a diffuser (compensating jet) is to…maintain a blank mixture in a piston engine at low and high power settings.
Constant
For piston engines, mixture ratio is the ratio between the blank of fuel and blank of air.
Mass.
