Why more lift is required when landing?
During landing, the purpose is to slow down the aircraft's ground speed as slow as you can without it stalling. You want to maintain Lift, not necessarily get more lift. At higher speeds, the aircraft has plenty of Lift. However during landing, the speed is slower and the angle of attack is increased to provide more Lift at lower speeds.
Do you use flaps to land an airplane?
Yes, Flaps are both used to create lift (on takeoff) and to slow the aircraft (on Landing)
Movable sections on the wings which slow down the airplane?
Their are two items on a airplanes wing that can slow down the aircraft. One is that flaps located on the back of the wing changing the shape of the wing creating more air pressure on the bottom of the wing creating lift. Second their is spoilers or airbrakes on the top of the wing that decrease lift and increase drag causing the plane to slow.
What fluid force of opposes lift?
The fluid force that opposes lift is drag. Drag is the force that acts opposite to the direction of an object's motion through a fluid, such as air. It acts to slow down the object's movement, including an aircraft's forward motion.
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.
What is a body flap?
A Flap is a control surface that is used to kill the lift of a wing to allow the aircraft to descend. I've never heard the term "body Flap" but it must refer to a Flap or a "speed brake" that is located on the fuselage and is used to slow the aircraft. Military aircraft used speed brakes or Dive brakes to slow their speed when diving on a target to drop a bomb. Some aircraft with fuselage speed brakes is the A-1 Skyraider propellor aircraft of Viet Nam and I think the F-86 jet fighter.
What did they call jet lag before there were jet airplanes?
They didn't call it anything because before jet aircraft were invented all the other aircraft were too slow, and couldn't travel far enough distances for any real noticeable jet lag.
What causes an aircraft to stall?
The stalling of an aircraft wing is caused by the disruption of the airflow on the upper and lower surfaces of the wing, An airflow is travelling fast enough over a wing. A low pressure area develops on the underside of the wing and a very high pressure on the upper surface of the wing ......This is what causes lift- the force that allows the aircraft to fly. If this airflow is Broken or reaches a speed too slow to maintain the low pressure required to create the lift. The wing will stall
What causes the lift of an airplane?
Low pressure above the wing goes faster because the low pressure always takes the longer way ( The curved side of the wing). This is what creates lift. the engines just help the airplane move on the runway to go faster for it to be able to take off. This is how it works: the fast air/low pressure on top of the wing pulls the wing towards it and since the wing is attached to the plane the plane also moves up. The slow air/high pressure always takes the short way/the bottom of wing. The high pressure going on the bottom of the wing pushes the wing upwards and the plane goes with it. This explanation of "aircraft lift" has been taught in the text books for many years but is incomplete in its explanation of "lift". If this were the complete answer to "lift" we would see no aircraft ever flying upside down as the "lift" would quickly "lift" them right into the ground. There are many aircraft used in stunt flying which have almost completely flat wings which would develop no or insufficient "lift" to keep the aircraft aloft. More recent theories point to a more complete explanation of "aircraft lift". In addition to the very small "lift" generated by the curved upper surfice of some aircraft the angle of attack to the airflow is a more complete explanation of "aircraft lift." With the huge forces necessary to lift an aircraft such as some of the military cargo planes the amount of "lift" generated by the curved wing design would never be sufficient to get it off the ground let alone stay aloft, however the angle of attack through the air generating force on the lower surface of the wing can generate sufficient lift to get the aircraft off the ground. To some extent the greater the angle of attack the greater lift.
When matter loses its particles slow down?
When matter loses energy, its particles slow down. This decrease in kinetic energy leads to a decrease in particle movement and ultimately a decrease in temperature.
What is the slowest aircraft In the world?
It's pretty slow.
In an aircraft what is a spoiler?
On large passenger aircraft, there are flat panels on TOP of the wing that pop up to distrupt the airflow (or spoil the airflow) that passes over the top of the wing. This kills the lift for that part of the wing and causes the aircraft to descend. The spoilers are deployed by inputs from the pilot when he wants to descend. During landing, the aircraft computer detects when the aircraft touches down on the runway and automatically deploys them to ensure the aircraft doesn't bounce up and try to keep fllying and helps slow it down quicker.
