Aircraft can have different ways to take off and land. Conventional airplanes accelerate along the ground until sufficient lift is vertical takeoff and landing aircraft pdf for takeoff, and reverse the process to land. Some airplanes can take off at low speed, this being a short takeoff. Some aircraft such as helicopters and Harrier Jump Jets can take off and land vertically.
Rockets also usually take off vertically, but some designs can land horizontally. Takeoff is the opposite of landing.

The extended and splayed feathers act as lift augmenters in the same way as an aircraft’s slats and flaps.
