## What are the forces of descent?

4 Things That Effect Descent Performance

• Weight. A change in weight will affect the rate of descent.
• Flaps. The increased drag produced by the flap will increase the descent angle thereby increasing the rate of descent.
• Power.
• Wind.

## What are the 4 forces acting on an airplane?

The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.

What is the downward force that acts on an airplane in flight?

gravity
When an airplane is in flight, there is a downward force (gravity) and an upward force (lift) acting on the airplane. As an airplane moves through the air, the shape of the wings causes there to be less air pressure pushing down on the wings than pushing up on the wings.

How do each of the four forces act on an airplane in flight which direction does each force push or pull on the airplane in flight?)?

Lift pushes or pulls the airplane up. Weight pulls the airplane down towards earth. Drag pulls the airplane back to keep it from moving forward. And thrust pushes the airplane forward.

### What forces act on an airplane to keep it at a level altitude?

constant airspeed, thrust and drag must remain equal, just as lift and weight must be equal to maintain a constant altitude. If in level flight, the engine power is reduced, the thrust is lessened, and the aircraft slows down.

### What are the factors that affect aircraft stalls?

Factors such as total weight, load factor, power, and center of gravity location affect stall speed—sometimes significantly. Stall speed increases as weight increases, since wings need to fly at a higher angle of attack to generate enough lift for a given airspeed.

What happens when the four forces of flight are unbalanced?

Assuming a straight and level flight, lift must be equal to weight and drag must be equal to thrust. This is what happens if this equilibrium is violated: If lift becomes greater than weight, then the plane will accelerate upward. If the weight is greater than the lift, then the plane will accelerate downward.

What forces act on a paper airplane?

Four forces act on a paper airplane:

• Thrust – the force that propels their airplane (your arm);
• Drag – the friction between the plane and the air, slowing the plane down;
• Lift – the force that causes the plane to go up;
• Gravity – the force that causes the plane to go down.

#### Why can humans not fly?

Humans are not physically designed to fly. We cannot create enough lift to overcome the force of gravity (or our weight). Their light frame and hollow bones make it easier to counteract gravity. Air sacs inside their bodies make birds lighter, which enables smoother motion through air.

#### What are the four forces?

fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.

Does drag help a paper airplane go further?

The aerodynamics of a paper airplane will determine the distance and ease at which it flies. The aerodynamics of the plane will need to have little drag and be light enough to defy gravity. When these four forces are used in balance, paper airplanes will fly longer.

What will happen if CG is too far forward?

If the CG is too far forward, passengers can be moved to rear seats or baggage can be shifted from a forward baggage compartment to a rear compartment. If the CG is too far aft, passenger weight or baggage can be shifted forward. The fuel load should be balanced laterally.

## What are the forces in a climb or descent?

Set the airplane’s thrust using the blue slider to demonstrate how excess thrust counteracts the rearward component of weight and allows an aircraft to climb at a constant airspeed. Reduce thrust to show how the forward component of weight allows the aircraft to descend. Become a better pilot.

## Which is an upward force acting on an object?

The upward forces acting on any object descending through the air can include drag from air resistance, lift from aerodynamic effects, and thrust from engines etc. The downward forces obviously include gravity, but could also include thrust from engines and negative lift from aerodynamic surfaces.

What happens to the lift of an aircraft as it descends?

The total lift (aerodynamic force perpendicular to the aircraft’s path with respect to the air) will be reduced. Thrust and drag may may also be reduced depending on the air speed. In an aircraft that is descending at a constant rate, not only is there lift acting on it, but that lift is equal in magnitude to the aircraft’s weight.

What happens when the angle of descent increases?

The weight force increases as the angle of descent increases resulting in a shift in weight, which means adjustments must be made to the lift and drag ratio. The rate and angle of descent will depend on the required altitude at the end of the descent, and the distance you have to complete the manoeuvre. Weight.
