The wings are the primary source of lift for an airplane. The horizontal stabilizer of most modern transport aircraft produces lift also, but the lift vector of the stabilizer is usually in the opposite direction (down) in order to keep the aircraft at the proper pitch attitude.

Some aircraft configurations are designed so that the aircraft body itself provides lift. The Space Shuttle is an example of a "lifting body" aircraft.

What is the force that counteracts the weight of an airplane?

The force that counteracts the weight of an airplane is called lift. Lift is generated by the wings of the airplane as it moves through the air. The amount of lift produced needs to be equal to or greater than the weight of the airplane to keep it in the air.


What are the forces on a airplane when it is still?

When an airplane is still on the ground, the main forces acting on it are the gravitational force acting downwards and the normal force exerted by the ground acting upwards to support the weight of the airplane. There are typically no aerodynamic forces acting on the airplane until it starts moving.


How do you measure the weight of an airplane without disassembling the plane or using any weight measurement tools?

Measuring the weight of any body requires a tool to measure it. A measurement without a tool is an estimate, not a measurement.Measuring the weight of an airplane without a measuring tool cannot be done.


What is the force that counter acts the weight of a airplane?

The force that counteracts the weight of an airplane is lift, which is generated by the wings as the airplane moves through the air. Lift opposes the force of gravity acting on the airplane, allowing it to remain airborne.


Will an airplane be lighter when birds fly inside the airplane than sitting floor?

No, the weight of the airplane will not change when birds fly inside. The weight of the airplane is determined by factors like the total mass of the plane, fuel, cargo, and passengers - the presence of birds inside will not significantly impact this total weight.

How many x table legs are needed to support the weight of the table?

The number of table legs needed to support the weight of the table depends on the size and weight of the table. Typically, a table will have 4 legs to provide adequate support.

How do they know a commercial airplane is overweight?

The weight of an airplane is calculated by the pilots. The pilot takes the empty weight of the aircraft, adds the fuel, adds a standard weight for each passenger and the measured weight of all the baggage. If this weight is over the maximum allowed weight, the airplane is overweight and they will send some luggage on another flight.
