Hard Landings

[Jetflyer]

"Another good way which needs alot of practice is to use the throttle (i.e. speed) to adjust the pitch and the trim to control
the speed."

That's not really the technique for landings in jetliners, the trim should never be used for corrections on final approach in a fast jet airliner,
maybe on general aviation planes, because they only have small trim tabs, on most jetliners the whole stabliser moves. The trim should be set after
the final flap setting, power setting and attitude are set for the glideslope, and the power setting should be constant to keep a constant speed at
the same descent rate. Small adjustments to pitch should be made with the elevators on final approach and not power setting or trim.

Having done 405 flights on FSP in jetliners with an average of -140fpm touchdown, that's how well the technique works, because it's the only real way to do it. There are huge differences between landing a GA plane and a jetliner.

ohh, I misread, pitch to control speed, yes. Trim to control speed, only in the case that you trim for approach speed and leave it there, like I
described in apporaoch procedure.

Actually, that was what I was trying to say.
Sorry for any confusion...

You have to balance the speed. If you go to fast, you ballon. If you go to slow, you stall. In my opinion, balloning is better and safer. You
rarely crash from a ballon landing, but you can crash lots of time from stalling right before the runway.

I used to have the stall problem until recently. I would alwyas stall on landing. I was so preoccupied with flying the approach manually,
that I didn't track the speed. I don't really know how I solved my problem, but now I don't stall on landnings. The last time I stalled was
about 2 months ago. However, I do use more throttle on landing from then on.

well that balloon can cause you to ride your plane down the runway like a horse and in the end you could stall and crash... so..... (im
talking GA)

I've done that many times. Before I got good at landings.
