What is the device in an aircraft wing to reduce lift and decrease speed?
Airplanes use a combination of slats and flaps in order to increase lift and increase drag. The slats are located on the leading edge of the wing and the flaps on the trailing edge. Flaps and slats when extended forward and aft increase the wing area which increases lift. When the flaps and slats are further extended they curve downwards increasing the camber of the wing which also increases lift. The greater the lift, the greater the drag. Deploy the flaps a little and lift overcomes the drag, fully extend them and the drag overcomes the lift. For takeoff the flaps and slats may be extended just a few degrees to increase lift. When flaps and slats are fully deployed in landing configuration, the lift is great but so is the drag and this in turn helps to slow down the airplane on decent to land.
Can you change the four forces in flight in any way?
Of course. That's exactly how you steer an airplane. -- Running the engines faster increases the thrust, which increases the airspeed. -- Increasing the airspeed or the angle of attack increases the lift, which makes the plane climb. -- Increasing the drag causes the airspeed to decrease, which causes the lift to decrease. -- Decreasing the airspeed or the angle of attack decreases the lift, which can be used to lose altitude. -- Using control surfaces to increase the lift of one wing while decreasing the lift of the other wing causes the airplane to bank toward the wing with less lift. -- Increasing the angle of attack during a bank causes the plane to be 'lifted' around a turn. -- Extending flaps increases both lift and drag. If thrust is maintained at the same time, the airplane loses airspeed but maintains altitude. Anything you want the airplane to do is accomplished by manipulating the four forces in flight.
As air molecules move over and under wings of an airplane the pressure increases below the wings to create which of the following?
Lift
Why drag increases as lift increase - for helis?
The production of lift creates induced drag. To create more lift, more airspeed is needed, and with airspeed, comes drag.
What is the purpose of increasing or decreasing the angle of incidence of a particular wing?
An airplane wing flys by Newton's third law--by thrusting large volumes of air downward (regardless of what you may have heard). This upward force is called lift. The downward force is gravity, the engine causes forward thrust and there is plenty of drag caused by the airplane moving through the air (from several sources). Increasing the angle of incidence slightly causes the lift to increase but also the drag. Thus the airplane may go up but also slow down. Lowering the angle of incidence causes the lift to decrease, the drag to decrease and the speed to increase. How these things balance and the resulting lift/drag is up to the designer of the wing.
What does airplane swing contribute to the lifting force force on an airplane?
When the wing is straight it creates more 'lift' . When swept it allows more speed.
How could you increase lift on an airplane's wings?
increase the angle of attackOr speed up the airflow across the top
What is affected by an airplane's speed?
Airflow ans lift over the airframe is affected by the airplane's speed.
What are the purposes of the slats and flaps of an airplane's wings?
Slats and flaps increase drag and also increaselift. The increase in drag slows the aircraft down, and the increase in lift lowers the stall speed, which slows the landing speed of the aircraft.
How could you make an airplane rise faster into the air?
Increase speed and/or lift. You want the pressure above the wing to be lees than below. In very short times like takeoff, the flaps are increased to sacrifice speed for lift. As the a/c speed increases the flaps are slowly retracted until the wing is at its optimal setting. (Flaps moving is that mechanical noise you hear during takeoff and landing).
How does an airplane achieve lift?
The speed of air over and under the wings creates pressure which is lift.
How do flaps increase lift on an airplane?
Basically they 'curve' the wing, forcing the airflow to lift more weight.

What is the use of flaps in airplanes?
Flaps increase the aerodynamic lift of a wing by increasing it's surface area. This allows the airplane to generate a greater amount of lift at slower speeds. In other words, when the flaps are extended, the airplane doesn't have to go as fast in order to take off or land. The flaps are retracted once the airplane is off the ground and has increased its speed to a point where the extra lift from the flaps is no longer needed. Flaps also have the effect of increasing drag on the airplane wing which reduces the airplane's speed and efficiency, but this only affects the aircraft when operating at higher speeds.
How does an airplane's design allow flight?
Aircraft consist of a few major sections, the Wings, Empennage, Flight Controls and Fuselage. As the speed of the aircraft increases winds travel under the wings at a faster speed then going over the wing causing Lift. As long as there is enough lift it causes the Aircraft to fly.
