Take-Off & Landing
|
The WEIGHT force is bigger than the LIFT force What happens as the aircraft goes faster |
|
Now the LIFT force is bigger than the WEIGHT force
The forces are unbalanced, and the aircraft starts to rise How does the pilot get back down safely |
|
The spoilers increase the DRAG force, to slow down the aircraft. As it goes
slower, the LIFT force gets less and the aircraft starts to descend
As the aircraft slows down, the pilot extends the flaps at the back of the wings. This increases the lift so that the aircraft does not fall out of the air
How can the pilot stop the aircraft quickly when it has touched down on the runway Deflect the exhaust air forwards (on many aircraft this can be done to slow them down when they have landed). Now the THRUST force is forwards, and helps to stop the aircraft. Of course, pulling on the brakes helps as well |
