If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range you may have been
Operating with too much power and with the mixture set to lean.
When operating an aircraft with a constant speed propeller which procedure places the least stress on cylinder components?
When power settings are being decreased, reduce manifold pressure before RPM.
What is the main reason fuel tank vents must be open? To allow
Proper air pressure within the tanks for maintaining a steady fuel flow
When refueling aircraft which precaution would be adequate for eliminating the potential hazard for static electricity?
Connect a ground wire between the aircraft,fuel tank, fuel nozzle, and ground
As flight altitude increases, what will occur if no leaning is made with the mixture control?
The density of air entering the carburetor decreases and the amount of fuel remains constant.
Proper mixture control and better economy in the operation of a fuel injected engine can be achieved best by use of
An exhaust gas temperature indicator.
Fuel/air ratio is the ratio between the
Weight of fuel and weight of air entering the cylinder.
Fuel injection systems, compared to carburetor systems, are generally considered to be
Just as susceptible to impact icing.
The presence of carburetor ice in an aircraft equipped with a fixed pitch propeller can be verified by a applying carburetor heat and noting
A decrease in RPM and then a gradual increase in RPM
The first indication of carburetor icing in an aircraft equipped with a constant speed propeller would most likely be a
Decrease in manifold pressure.
The low temperature that causes carburetor ice in an engine equipped with a float type carburetor is normally the result of the
Vaporization of fuel and expansion of air in the carburetor.
Concerning carburetor icing which statement is true?
Carburetor icing would most likely form when the air temperature is between -7°C and 21°C and visible moisture or high humidity is present
Running a fuel tank dry before switching tanks is not a good practice because
Doing so may allow air to enter the fuel system and cause vapor lock
During which stroke of a reciprocating engine is the gaseous mixture expanding within the cylinder?
Power
During climbing flight using a turbocharged airplane the manifold pressure will remain approximately constant until the
Engine’s critical altitude is reached.
