What action can a pilot take to aid in cooling?
What action can a pilot take to aid in cooling an engine that is overheating during a climb? A. Reduce rate of climb and increase airspeed.
How does an aircraft piston engine start?
Magnetos generate electricity when they rotate. So, to start the engine, the pilot must engage a battery-powered starter that rotates the crankshaft. After the magnetos begin rotating, they supply the spark to each cylinder to ignite the air/fuel mixture and the starter system is disengaged.
How is engine operation controlled?
How is engine operation controlled on an engine equipped with a constant-speed propeller? The throttle controls power output as registered on the manifold pressure gauge and the propeller control regulates engine RPM.
What change occurs in the fuel air mixture?
What change occurs in the fuel/air mixture when carburetor heat is applied? A decrease in RPM results from the lean mixture. The fuel/air mixture becomes leaner.
Who is primarily responsible for maintaining an aircraft in airworthy condition?
The owner or operator of an aircraft is primarily responsible for maintaining that aircraft in an airworthy condition (14 CFR 91.403). These duties, as outlined in 14 CFR 91.403, 91.407, and 91.417, include ensuring that: Required inspections are performed. Discrepancies are repaired.
What is the benefit of flying with a glass cockpit?
The controls in a glass cockpit have fewer mechanical components to break down or return false readings. The biggest advantage to a glass cockpit over traditional cockpits is that the automation systems are more accurate, the information is more precise, and the data is displayed more ergonomically.
Why do you start engine 2 first?
2 Answers. The isolation valve in Open or Auto ensures that the Auxiliary Power Unit (APU) bleed air reaches the engine number 2 starter. Engine number 2 start Exhaust Gas Temperatures (EGT) are generally higher. Engine number 2 is started first because it’s on the opposite side of the air bridge.
Do airplanes have keys?
So, Do Airplanes Have Keys? Some smaller aircraft, including the Cessna, have ignition keys that are needed to start the engine, while many larger planes do not use keys. As a general rule, larger commercial planes typically do not have keys.
How does a turbine engine start?
The compressed air passes through a small turbine on the outside of the engine, causing it to spin. Attached to the turbine is a shaft which is joined by gears to the main engine shaft, and that begins spinning as well. “The blades connected to the engine shaft then start rotating faster and faster,” explains Brand.
What is an advantage of a constant speed propeller?
A constant–speed propeller is able to partly rotate along the longest axis of the blade to take a larger bite of air with respect to the airplane, allowing the propeller to maintain the most efficient orientation to the airflow around it.
What is manifold pressure in aviation?
Manifold pressure is the pressure in the fuelair mixture between the throttle and the engine. When the throttle is at low power, then it is preventing fuelair from flowing which causes a reduction in pressure.
What is the indication of power in a fixed pitch propeller?
In a fixed–pitch propeller, the tachometer is the indicator of engine power. [Figure 7-8] A tachometer is calibrated in hundreds of rpm and gives a direct indication of the engine and propeller rpm. The instrument is color coded with a green arc denoting the maximum continuous operating rpm.
What type of fuel can be substituted for an aircraft?
What type fuel can be substituted for an aircraft if the recommended octane is not available? A) The next lower octane aviation gas. B) Unleaded automotive gas of the same octane rating.

What is the remedy for suspected carburetor ice?
In most cases, pilots can get rid of accumulations of carburetor ice by using carb heat. Nothing more is necessary. This proves that the system works as designed—warming the carburetor venturi and body—especially if we are conscientious in applying carb heat before reducing power.
Which condition is most favorable to the development of carburetor icing?
Carburetor ice can form under a wide range of conditions, but temperatures between 20 and 70 degrees F, with high humidity, are most conducive to ice formation.
