how to land
Depends on the type of aircraft . Line it up , avoid manoeuvres at low altitude , pull a little "up" to slow down just before your plane hits the ground but don't stall it . Always try to land " into the wind" . Make short flights but many landings , keep on practicing ... GOOD LUCK !

how to land
A properly trimmed trainer will practically land itself... just reduce throttle to idle, and use gentle rudder control (maybe a touch of up after each turn) to line up with the runway. If its trimmed right.. thats it. If its trimmed to fly level at ful throttle...you'll have to hold a bit of up elevator durring the descent, right until the wheels touch.
The lower the touch-down speed (as long as you haven't stalled 5 ft off the runway...) the prettier the landing will be.

If you are flying a trainer airplane, take it up and check to make sure the plane will fly level and at midrange speed hands off the controls.
Now pratice landing approaches and each time get a little lower as you come by where you are. Find the altitude which feels confortable to you to start your approach with.
Now find out how many clicks of power it takes to just fly level at a lower power setting.
You may need to adjust elevator a little so that your plane will fly level.
When you have determined how many clicks of throttle it takes to fly level you now know and should have confidence as long as your engine is running that your plane will fly, and kinda slow (remember you can get too slow and your plane will stall if the conditions are right,
on your approach from turn 4 watch your plane and as it just comes past the end of the runway reduce your throttle a few clicks and drive your plane all the way until it stops rolling.
Flair just slightly as your airplane almost touches down, back pressure on the elevator.
Once you touch down reduce your power as needed and drive your plane until it stops rolling.

Yes! When it comes time to land for the very first time, there is a incredibly important tip that everyone here seems to have missed - you don't take your eyes off the plane, and ask the instructor beside you for some help in guiding the plane to the ground! [img]i/expressions/face-icon-small-smile.gif[/img]
ok, sorry about that [img]i/expressions/face-icon-small-smile.gif[/img] but yes you should get help from an instructor. Here's a neat little webpage that can help you - it gives tips on takeoff, flying and landing.

That looks like a beautiful flyer to try to land right side up![img]i/expressions/face-icon-small-happy.gif[/img]
USUALLY, the first go-round on the flying field, before my battery is any weaker, (I fly electrics only) I make an approach to land. It is High, but I want to see how well it will glide, how fast, and how far, before it really drops.
I did it this morning, and when the time to land came, I brought it down, and on a grass landing it stopped about 3 steps in front of me. FINALLY I'M LEARNING![img]i/expressions/face-icon-small-wink.gif[/img]

No Bill, you were right. You have to land right-side up. That plane is just built upside down [img]i/expressions/face-icon-small-happy.gif[/img]
The Predator UAV has the same kind of tail but lands normally. You can see they had to use tall, spindly landing gear to stop the tail from hitting. The propeller is also back there trying to hit the ground! [img]i/expressions/face-icon-small-blush.gif[/img]

I spent some time this AM contemplating how to answer your question as concisely as possible. Trying to distill a complex process to a few lines is hard to do. These are my thoughts on how to do this.
First Rule - Airplanes have to have airspeed to fly. Its like Star Trek's "Prime Directive" - always maintain airspeed!
The principle of landing is that you want the lift to decrease below the pull of gravity but be present enough to continue controlled flight so that the plane settles gently to the desired landing site. The important concepts needed to do this is:
1. The throttle controls altitude and rate of descent. In order for a plane to go up, it must generate energy to create airspeed. The more thrust, the more airspeed, the more lift to overcome gravity and up goes the plane. The opposite is true to descend. Reduce the power, reduce the airspeed, reduce the lift and gravity pulls the plane back to earth.
2. Airspeed is controlled by elevator. Elevator does not make the plane go up. Back elevator (commonly called "up") increases angle of attack, increases lift at the sacrifice of airspeed, slows the airplane down and then lift is lost and the plane descends. Do it too much and a stall is created and the plane really falls fast. Foreward elevator (commonly called "down") increases airspeed in the reverse of the above sequence.
So the way to land is to reduce airspeed by throttling back but maintain enough airspeed to maintain control of the plane. I do this when the plane is at a low but comfortable altitude across from me from the landing zone. That's called "downwind". You should be landing into the wind. The plane will start to descend and when at the far corner of the runway I turn 90 degrees toward the runway - to the "base" leg. Continue to descend using throttle to control the rate of descent and elevator to maintain airspeed. If you are descending too fast, add power if not descending cut the power down. Foreward elevator to incease airspeed and back elevator to decrease airspeed. The trick (that needs practice) is to use this combination to get the plane to reach the ground at a low airspeed just as it is over the runway.
Then you make another 90 degree turn onto "final" and continue the descent process until is about a foot or so above the ground. At this point apply increasing "back" elevator to reduce lift and airspeed so that the wheels touch the ground when there is no lift left in the wings. That's called the "flare." The main wheels should touch first. Flare too high, and the plane stalls and the nose drops and the front will impacts first - that's not good. Flare too late and the nose hits first - that's not good. Its a timing thing.
Lastly as mentioned before - keep "flying the plane until it stops". That is just because the plane is on the ground doesn't mean to let go of the controls. The job's not done until the plane rolls out to a stop.
That's my insight on the matter. Hope it helps.
