How do big aircraft stay in the air?
Big aircraft stay in the air primarily through the principles of aerodynamics. As the aircraft moves forward, its wings generate lift due to the difference in air pressure above and below them, created by their shape and angle of attack. Engines provide the necessary thrust to overcome drag and keep the aircraft moving forward. Additionally, the overall design and weight distribution of the aircraft play crucial roles in maintaining stable flight.
What types of force can an airfoil exert?
An airfoil can exert lift, drag, and thrust forces. Lift force is generated perpendicular to the airflow and is essential for providing the upward force needed for an aircraft to stay aloft. Drag force acts opposite to the direction of motion and resists the aircraft's movement. Thrust force is generated by the aircraft's engines and propels the aircraft forward.
What makes aircrafts to fly hundreds of feet above ground and not be atracted by gravitational force and loose altitude?
Aircraft fly and stay in the air because the force of gravity is balanced by the force of lift created by the wings as air rushes over them, and because the force of air friction is balanced by the force of thrust created by the engines.
Can a jet airliner stand still in mid air?
No. Aircraft need an air stream passing over the wings to maintain lift for it to stay up. The only aircraft of a jet type that could do this was the Harrrier Jump Jet which could turn its engines through 90 degrees to basically hover.
Describe how an airplane stays in the air?
This is interesting: The engines produce forward thrust, which in turn makes the aircraft go forward. The wings are airfoil-shaped, so, when the aircraft moves forward they push air downward, which in turn pushes the aircraft upwards.
Why does Honda make such good engines?
Honda makes good, quality engines because they use high grade components, hire experienced workers, and follow strict guidelines. This allows them to stay at the forefront of engine manufacturing and sales.
How dangerous are planes?
Well, planes are very dangerous depending on how you fly but the most important part is the engines. The engines of the plane are extremely dangerous because they are really powerful enough to suck your whole body in. This means that these airplane engines can really kill you. The most important is to always stay away from the engines of the aircraft(airplane) while they are running. These engines are so powerful that the aircraft can really fly. Planes can be even more dangerous if you don't try to be careful. During flights, you must never get close to emergency doors, never put items on or near emergency doors and never ever open emergency doors while the aircraft is in the air. One more thing you need to know! Never ever sit on emergency doors during flights. Airplanes can and will become even more dangerous than they really are if you don't follow the safety rules.
What are the 4 forces of aerodynamics?
The four forces of flight acting on an airplane in flight are, Lift,Weight,Thrust and Drag. They are all in equilibrium when an unaccelerated flight is exist.

Why aircraft and planes are not attracted by the force of gravity?
They certainly are. Just shut down the enginesand see what the aircraft does. In fact, they overcome gravity by generating a counteracting force called lift using the air motion over their wings. Gravity is still there, it's just that the net downward force has been reduced to zero.
How do aircraft propellers keep the aircraft airborne?
For an aircraft to stay aloft, the an air current has to move over the wings in a specific way. The propellers generate the air current and direct it in the proper way to keep the aircraft airborne.
Can an airplane fly without an engine?
If an airplanes engines fail in flight, the plane can glide for a distance ( depending on it's altitude ), but gravity will eventually bring it down.While most manned airplanes have engines,there are a variety of airplanes that are designed to fly without an engine:sailplane, hang glider, paraglider.Such aircraft can theoretically stay aloft indefinitely in several ways:* towed by a ground vehicle or a powered aircraft* tethered to the ground, with wind (like a kite)* taking advantage of updrafts and ridge lift to gain altitude
