How come whenever I land aircraft sometimes it performs somewhat of a wheelie?
Sometimes it rolls on the main gear for some distance
How can I prevent this?

I'm speaking of larger aircraft such as the crj-200 and sometimes the 737-700...
I usually land at 130 knots, at around -100/200 fpm
I then deploy spoilers and reversers and it still sometimes wheelies.

Hey Blackalpha,

Do you adujust your attitude with the Stab Trim (elevator trim) when on approach? You should be able to take your hands off the stick on an approach and the plane will continue on the correct descent profile if you're doing it right. Maybe when you let go of the joystick to do the reverse thrust, it's pulling the nose up again...

It might also be that under "fuel and payload" there's too much weight at the back of the plane.

At the end of the day, it's not a disaster to wheelie. I often deploy the spoilers and hold a 737 at about 5-8 degrees nose-up all the way down the runway, using only the spoilers to slow down . That way i don't even need reverse thrust.

Try it for something different.
Bromster.

That's what the pilot is for, to convince the plane it wants to be on the ground. Sometimes it is just a teensy bit too much flaps for the runway length chosen. Some modern aircraft use dynamic fuel transfer programs as a function of aircraft trim. I am not certain if anybody has managed to model it in FS though.

A "wheelie" or more appropriately called a flare, is an important and vital step in landing. Anything else (landing nose gear first, or all three at once) is almost always "wrong".

Assuming you know that already, getting the nose down can sometimes be a problem. With the way I like to trim, the nose usually comes down if I let go of the stick, but usually even that makes the nose hit the ground a bit hard. If letting go of the stick doesn't put the nose down, try giving a little forward pressure on the stick. Also, make sure everything that helps stop the plane before landing is armed/set, so you don't have to manually do it once on the runway. For example, set your autobrake, and arm your spiolers, and according to runway length, flaps.

EDIT: I guess everyone has their own individual landing style. For example, bromster holds the nose until the wings can't hold it up anymore, while I have the nose on the way down as soon as my main gears touch.

From a passenger perspective, getting the nose down allows for front brake participation and helps smooth out some of the bumps from the runway. "Riding" the main gear can sometimes be a bit unsettling on some of the older runways and military runways.

Basically they covered it, but I had to add in that that's a nice pic Bromster, looks nice with the sunset behind.

Thanks Robbie!!! Don't be fooled! I actually paused the sim and adjusted the time to get the perfect sunset pic! Laughing

737's don't have front brakes.
