Here's a very simple answer to a very complex question:
To take off, an aircraft must accelerate to a fast enough speed so that the airfoils (wings) generate sufficient lift for the aircraft to overcome gravity (its weight) and become airborne. This is accomplished through the use of engines that produce thrust--jet engines or propeller engines, for example--which move the aircraft forward through the air.
To land, the thrust is reduced gradually so as to reduce the speed which reduces lift which, in turn, allows the aircraft to descend.
Again, this is a very simplistic explanation to a very complicated process.
What else can I help you with?
What is the place where airplanes takeoff and land called?
It is called a runway, and it is also referred to as the tarmac, which is what the runway is made out of.
Why do airplanes takeoff?
There is not much point in having airplanes unless they 'take off' .
How many airplanes takeoff and land at LAX daily?
Los Angeles international had 622,506 aircraft movements (takeoffs and landings) in 2008 an average of 1701 a day.
How do airports ensure that runways are safe to takeoff and land on?
Runways are created with enough space to ensure that airplanes have plenty of room to take off and land, even in adverse weather. They are kept clean and free of obstacles that might get in the way of planes mid-takeoff. They're also inspected regularly by the FAA (Federal Aviation Administration).
Why do window shades have to be open for takeoff on airplanes?
Window shades have to be open for takeoff on airplanes for safety reasons. In case of an emergency, having the shades open allows passengers and crew to see outside and assess the situation, which can be crucial for evacuation or emergency response.
Where do airplanes land?
Airplanes land at airport or airstrip or any flat level land.
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.
Does the F-22 have vertical takeoff?
No. The F-35 which looks similar can takeoff and land vertically.
Why do airplanes need so much speed to take off?
Airplanes need a lot of speed to take off because they are not designed for vertical takeoff and are to heavy to do so.
Is the arrival time of airplanes when they land or the doors open?
the time is when airplanes land
What does VTOL aircaft have the ability to do?
VTOL craft can takeoff and land vertically. hence Vertical Takeoff Or Landing
Where do planes land and takeoff?
In an airport...
