What role do engines play in aircraft performance?

Engines are crucial components in aircraft performance as they are responsible for generating thrust, which propels the aircraft forward. Thrust is the force that moves the aircraft through the air and overcomes drag and other forces acting against it. The efficient operation of engines allows the aircraft to take off, climb, cruise, and land.

While stability and navigation are important aspects of flight, they are managed by other systems such as control surfaces (like ailerons and rudders) and avionics rather than the engines themselves. Fuel consumption is also a critical consideration, but the primary role of engines in performance is to produce the necessary thrust to enable flight. Thus, their function as the source of propulsion is fundamental to how effectively an aircraft can operate in various phases of flight.
