An
airplane lands on the main landing gears with nose-high attitude.
When I was a kid, it looked mysterious to see an airplane actually
descends even when the nose points upward. Basically, you are
supposed to approach to a runway with nose-low attitude, and pull the
nose up seconds before touch down. (Although some airplane
approach with nose-high attitude like Concordes.)
But, I suppose that many of flight simulator pilots
feels it difficult to land on the main landing gears with nose-high
attitude. So, I'd like to talk about flare (pull-up before touch
down.) Actually, it's not so difficult to flare in a PC flight
simulator, and you can do it after a little practice.
What you need to practice first is to fly
super-low altitude, like 15ft above ground. You can begin with
30ft above ground. After taking off, climb up to 300ft or so, then
descend to 30ft and stay that altitude for some moment. At first,
you can just neglect the airspeed, but I suggest to fly no faster than
150kt. If you are flying too fast, slight motion of the stick will
easily give you 20 to 50ft climb/descend, and you may crash into the
ground. After flying at 30ft above ground for several seconds,
climb back up to 300ft and do the same thing over and over again until
you feel it easy and never fail. This practice is somewhat boring,
but fly super-low altitude is the basic of the flare, and you need to be
able to do it.
After you get used to it, then reduce speed to the
landing speed and do the same thing. Diamond Eclipse used in the
example should approach at 65 to 70kt. Because of the low speed,
unless you pull up the nose enough the airplane will sink and crash into
the ground. Then lower the altitude to 15ft above ground.

low altitude like this.
When you are able to do it, land with nose-high
attitude is easy. Approach to the runway just like you did when
you were practicing a low approach, and when you are flying super-low
altitude over the runway, reduce the throttle to idle. The speed
will decrease and the airplane will sink automatically and land on the
main landing gear. After reducing the throttle, you should try to
keep the airplane afloat as long as possible. However, if you do
this in a large airliner, you may end up with hitting the tail on the
ground before the main landing gear reaches the ground. So, when
you are flying an airliner, you also should be careful not to pull up
the nose too much.
Well, doing it on the runway maybe a bit difficult
first. So, I suggest you to take advantage of the flight
simulation; practice over the ramp area. In YSFLIGHT, you can land
on the ramp area, which is much wider than the runway. You don't
have to pay attention to the lateral deviation of the approach course if
you approach to the ramp area. Of course, if you do it in the real
airport, you'll be arrested for the violation of Federal Aviation
Regulation, unless you were in emergency. But, you don't need to
worry about the regulation in the flight simulator. You can just
concentrate on practicing flare. Maybe the ramp area of the Misawa
airbase of AOMORI map is appropriate for this practice. You can
also download the sample flight record file from the following link.

Well, I am writing this explanation as if I were a
flight instructor. However, in the real world, I'm still
struggling to do flare better. Of course, I can do it just
sufficiently well for acquiring the private certificate. But, my
landing is far from a nice smooth landing demonstrated by an instructor.
I wish I could practice landing as many times as I want. But, I
can do up to 10 landings in one practice even if I spend whole two hours
for touch and goes. In a flight simulator, you can practice
landings as many times as you want until you are really good at landing.
