iu98haha thanks, yea i know my feild elevation and i do have my books from ground school

...i just got confused my instructor said get an instrument flying handbook cause it was a required course material, but instrument certification is my second to last rating in my program....my instructor is like a drill sergaent, no matter if it is the right question and i know it is, he still critiques it...which is good i guess just trying to make me 'better'.... i do communicate with my instructor but i also like to here what other people have to say aswell

well let me correct that i just recently started communicating with my instructor on the level i should be...
also when i turn final at a non towered airport without any vasi/papi lights i get nervous on if i'm too high or too low, i'm always concerned i'm going to let my main gear touch right before the threshold....each and everytime i make a landing i get more and more comfortable its what i anticipate doing when flying now ...my flight instructor says it just takes a lot of getting use to the plane and so on...and when making a crosswind landing on friday i crabbed into the wind all the way until i was right over the numbers and about 20ft in the air, then i noticed when trying to correct the plane to center it,,i couldnt put enough rudder in to get that thing straight, did i come out of the crab to early and was crosswind still affecting me at this point? I say any landing is a good landing as long as the elt don't go off LOL and u stay somewhat around center line
OK, good deal... I was concerned you were only speaking up here; it's important to get as much out of your instructor and flight school as you can- they're getting paid, after all (sort of ;D ).
As long as the CFI isn't unreasonable and is willing to elaborate on his criticisms if you ask him to, it's definitely good for him to be a little hard on you.
The "oh crap I'm too low!" feeling is normal; don't worry about it; sounds like you're doing OK. The day you
do undershoot, believe me, you'll know- and if the engine is running, you'll be able to deal with it. But it's surprising sometimes how easily you can flare perfectly even though it looks like you're going to slam it down on the threshold or the numbers, but as long as you're not sinking too fast and you're not slowed-up too much, it'll work like a charm every time. Getting psyched-out by that approaching target zone can lead to floating or flaring too high (done it more than once, myself), so just think ahead and you'll do fine.
Straightening out from a crab to land is more an art than a science- depends on so many variables, it's hard to describe it. Different every time. Best way to get the hang of it is practice, like every other part of flying. And VASI/PAPI is very helpful, but those generally guide you to a point well beyond the numbers. You've got to work on setting things up so the place where you plan to flare stays centered in your field of vision... otherwise, you'll be lost trying to make a short-field landing where there is no glideslope indicator (like an emergency landing off-airport, for example...

)
And if you're too high, start by pulling back the power. As long as you stay at Vbg or above after that, you won't undershoot. If it doesn't look like you can get to your target without diving and you don't want to slip, just go around. During my training, I was always embarassed to go around. First time I had to do it solo, I got over it. As long as you have enough fuel for another circuit, going around is an excellent choice. More people bend airplanes trying to fix crappy approaches than by going around...

Not sure exactly what happened on the landing you described, but yes, sometimes there's just not enough rudder, depending on the wind. How did that landing turn out, anyway? Did you drift off-center, or touch down crooked? If you're drifting in the flare, you have to lower the upwind wing a little; if you're crabbing in the flare, you need rudder. But if you're going straight but a little off-center, you may want to just go with it, rather than dropping a wing when your airspeed is low and you're very close to the ground, and make a note to get set up better next time.
