For jet engines, higher thrust requires higher hot section temperatures. And higher temperatures reduce engine life, so commercial jets usually do not use full thrust on takeoff. Instead, the needed engine pressure ratio is calculated based on weather conditions, load, and runway length.
Military fighters and smaller general aviation aircraft use all they have on takeoff.
Do military transports use reduced thrust on takeoff, like the C-17?
Yes. JATO units (Jet assisted take off) have been used on aircraft since WWII.
How_much_fuel_does_a_747_use_on_takeoff
You need to be more specific with your question, like which specific aircraft you mean. For example a big aircraft like a 747 needs a lot more thrust than a leer jet just to get off the ground.
the jet engines create thrust and when there is enough thrust or speed, the airplane takes off because of the airfoil shape of the wings which makes low pressure on the top of the wing and high pressure on the bottom.
Any amount of thrust that's greater than the weight of the rocket vehicle will lift it off of the ground and accelerate it upward. If you keep it up long enough, the vehicle will be in space.
the harrier has four rotary nozzles that can direct the thrust downwards. This means that the harrier can perform a smooth VTOL. (vertical take-off and landing) during normal flight the nozzles are turned back into the horizontal position.
Thrust.
The most successful fixed wing aircraft with vertical take off capability is the Harrier. It uses four swivelling jet nozzles to angle the thrust straight down and thus rise up on a column of air. Once airborne, the nozzles can be rotated slowly backwards to turn vertical into horizontal thrust.
When a jet plane moves on land, it is called taxiing. The engine thrust of the plane allows the plane to move without actually taking off until it is ready.

When a jet leaves the airport it is called take-OFF
