Which parts are used to control lift at low speed for takeoff and landing?
Flaps and slatsSlats and flaps
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)
A plane usually extends flaps from its wings during takeoff and landing What is a reasonable explanation?
The flaps help to increase lift, which is essential to the landing and takeoff phase[s].
What advantage do flaps and stats give an airplane?
Flaps and stats increase lift for takeoff and slow you down, for landing.
Why do planes have flaps on the wings?
Airplane wings are designed to be most efficient when at high altitudes, traveling fast, while providing as little drag as possible. Unfortunately this design inst the best for takeoff and landing. Flaps are used to change the shape of the wing to accommodate takeoff and landing requirements. Most planes have flaps on the front of the wings (leading edge flaps) and at the back of the wings. During takeoff flaps increase lift so a plane can take off with limited runway length and lower speeds. As the plane gains speed the flaps are retracted. On approach and landing you want to fly as slow as possible so the flaps are deployed in increments till landing speed is achieved. Landing slower means less runway needed to stop.
When are the flaps on an airplane most useful?
They are useful for takeoff to get lift and at landing for slowing down the plane.
Does a plane have to have flaps deployed on takeoff?
No. Not always. For many airplanes, it may be required if the airplane is fullly loaded.
Flaps up or down for a takeoff?
The first point is to understand what flaps do. They create more wing surface area when they are extended, therefor creating more lift at slow speeds. TAKEOFF: Depending on the aircraft you are flying, may be a Cessna 170 or a 747, it all depends on the manufacturer of the aircraft. They may say at when you have X weight, you need no flaps but when you have a completely heavier weight, you may need flaps. *do not use this information for real flying.
Which is a possible consequence of taxiing the aircraft with flaps extended?
The flaps, when extended, basically make the wing bigger which generates more lift. during takeoff, it helps to have as much lift as possible to aid the aircraft in it's ascent into the air. during taxiing, there is no real benefit to having the flaps out. the reason the flaps are extended during taxiing is to save time. if the flaps are extended while the plane is taxiing, it doesent have to do it later before it takes off.
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).
Is it common for Boeing 747-400 to have flaps 10 when takeoff?
Yes. 10 or 20 are the only take off flap settings.
How are the ailerons used at takeoff?
they help an airplane bank (turn) after they takeoff
