Do airlines buy engines?
The airline does not pay for the engines, but for the time they are flying. Now the engine manufacturer has a strong incentive to improve the reliability of its engines, but also a strong lever to push out third-party maintenance providers. The engines are owned by the airline or aircraft owner.
What type of engine is mostly used by airlines?
Opposed, air-cooled four- and six-cylinder piston engines are by far the most common engines used in small general aviation aircraft requiring up to 400 horsepower (300 kW) per engine. Aircraft that require more than 400 horsepower (300 kW) per engine tend to be powered by turbine engines.
What happens if one engine fails on a plane?
If an engine fails and is shutdown, the other engine’s thrust is increased to stop a decay in airspeed. This results in the aircraft wanting to turn away from the working engine and entering a turn. If left unchecked, this will result in loss of control of the aircraft.

How does the engine work in an airplane?
There are nuances to engine operations, but in general, if the pilot wants the aircraft to go faster the throttle is advanced; to slow down the throttle is retarded. But the RPMs stay the same because the propeller control hasn’t been moved.
Why do propeller driven aircraft fly at different RPMs?
Most internal combustion propeller driven aircraft fly at specific RPMs for the different stages of flight. For example, take-offs and departures are usually at the designed maximum RPM, while enroute the engine is usually operated at a slower and more efficient RPM.
Why do aircraft engines not have mixture control?
The reason for the mixture control that you won’t find in a car is that aircraft operate at a range of altitude far beyond what most cars do and as such the mixture needs to be able to be manually adjusted.
How does the throttle work on an aircraft engine?
So you see, a given RPM acts like a particular gear in a car and the throttle acts like the gas pedal. Once at cruise altitude cruise speed is set by reducing the throttle to the appropriate cruise power setting (measured in inches of mercury), and then the propeller RPMs are also reduced to the cruise setting.
