Primarily they throttle back to reduce thrust.
But they also usually will use the flaps, lowering the landing gear also increases drag reducing speed, and most large aircraft also have air brakes (spoilers) for reducing speed.
Small aircraft may also perform a "forward slip" maneuver. This is where the pilot will use opposite rudder & ailerons to make the aircraft fly a little side-ways. This increases the frontal area of the plane increasing drag & reducing speed.
They slow down gradually and lose height as they land
As the distance between the viewer and the plane increases the Plane appears to slow down.
Land
Airplanes land at airport or airstrip or any flat level land.
Birds slow down by changing the position of their wings to catch the air like a parachute.
the time is when airplanes land
yes
they were slow not as fast as todayswell they were slow airplanes
Because they can go straight up and down without having to have the distance to pick up speed or slow down like airplanes. Its the way they are built.
Retro rockets slowed the LM down to landing speed.
Many small and special STOL aircraft can fly as slow as 40 mph.
