A quarter of its weight
- Normally, the static thrust of an airliner is at least a quarter of its weight. If the airliner is empty, this can become as much as half of the weight.

Jan 29, 2015 · The thrust needed to sustain flight is about 1/18 of aircraft weight, and if you factor in the multiples given above, you will notice that if the aircraft can fly at full thrust in cruise, this fits nicely with a static sea level thrust force equivalent to one third of its weight force.
The plane needs just a little bit of thrust to stay stationary: The treadmill will move and the wheels will rotate, but the plane itself will stay in place. Any more thrust and it will move forward. $\endgroup$

The four forces making up the principle of flight are lift, weight, drag, and thrust. The forces all interact together to determine an airplane’s trajectory. Lift and weight are opposing forces, as are thrust and drag. All are equally important, and they must be balanced to maintain level flight. While the 4 forces oppose each other, they don’t all...
Bernoulli’s principle of flight is a simple concept to understand. Bernoulli’s theorystates that if a fluid flow speeds up, there is a pressure drop. Air acts just like a fluid. For aviators, this means that if the air is sped up above a wing, then there is a lower pressure above the wing than below. This speeding up is caused by the wings camber, ...
Four forces work together to determine an aircraft’s behavior. Lift, weight, thrust and drag. These forces, in isolation, are relatively simple to understand. Once you know about them, their interaction and effect on an airplane are relatively straightforward. Below you will find a list detailing each principle of flight. We will explain the direct...
So, we are sat on a flight, on the cruise, staring out of the window with a coke in one hand and a pack of nuts in the others. Lovely. While it’s nice inside the airplane, let’s think about what is going on outside the aircraft. It’s all about being balanced. Straight and level flight is the perfect example of what happens when all the flight force...
To climb, two things need to happen when discussing the principle of flight: – 1. The lift vector must exceed the weight vector 2. The thrust must exceed the drag To do this, the pilot does two things: – 1. They pitch the aircraft up (increasing the angle of attack and, therefore, the lift the wing produces) 2. They increase the thrust (preventing ...
The flight forces in descent are easy to understand. The airplane wing is generating some lift, but this is exceeded by the aircraft’s weight. The thrust vector will also be small, and if the airplane is pointed the nose down, the resultant force of the thrust and weight combined will exceed the lift produced. Again, it is important to note that th...
The principle of flight isn’t too complex. There are only 4 forces to remember; lift, weight, thrust, and drag. These forces interact and are all linked. How they are combined determines the behavior of the airplane. The aerodynamic theory doesn’t have to be complex. Want more proof? Check out our online courses. They make learning aviation theory ...
For a plane to stay in the air without moving, the 2 sets of opposing forces must equal each other – i.e., lift must equal weight, and drag must equal thrust. In reality, it’s extremely rare for this to happen, and a plane could only last a few seconds in the air without moving.
A heavy plane, or a plane meant to carry heavy payloads, requires more lift than a light plane. It may also require more thrust to accelerate on the ground. On small aircraft the location of weight is also important.
