airplanes and aircraft
The engines propel the airplanes.
Helicopter engines require substantial power to propel the helicopter vertically from a standstill. With regards to planes, yes obviously planes need powerful engines, BUT planes speed up to 200km/h on runways before they start flying.
Usaly
Yes, jets are planes but jets are mostly known as supersonic planes.
Smaller planes have piston engines, but bigger planes like the Boeing 717-777 and other planes have turbine engines
i guess when the engines are set to full thrust, and when the plane leaves the ground...
Planes fly by generating lift from the wings as they move through the air. This lift is created by the shape of the wings and the speed at which the plane is moving. Engines provide the necessary thrust to propel the plane forward.

its engines
The jet engines help propel the airplane forward at incredible speeds.
Ion engines use an electromagnetic or electrostatic force to accelerate ions of a substance, for instance a gas like xenon, or a substance like mercury, out of a nozzle, producing thrust. Ion engines have a very low thrust but a very high specific impulse.
