A "different" kind of touch and go...

[minitour]

Last time out I went XC in the 172P (did my PPL in a 152 - in case its relevent) when I came back, I asked approach if they had time to practice an ASR on the first touch and go...they said sure and started the approach...cool...so he tells me Im on final and I can start the descent to MDA...so I start to descend, and he tells me im x miles from the runway, so I start to slow it up for the landing...110 kts 10 flaps...slowing more to 90, 80, 70, 65, and I like to keep it there with 10 flaps...so the controller tells me to notify ry in sight, tell him I've got it, switch to tower, cleared for the option, great!...fly the approach, add flaps, down to the numbers, flaring, the mains touch, then the nosewheel, then Im airborn again...but not by choice...back down on the mains, then nosewheel, then back up...not by choice again...back down on the mains, nosewheel, back up...this time i say fukc it and add power, pitch it up flaps 10 go around...so....

WHAT DID I DO WRONG???

...just when I thought I had it...was I trimmed up too much? I thought at first I was too fast but there's NO WAY unless the pitot tube was blocked which it was fine when I checked out the plane when I was done...wasn't a crosswind thing cuz I was straight into the wind...maybe I caught a gust? too much flare? not enough flare?

thanks for the help and sorry for the long post

It sounds like a typical "hard" landing followed by a few bounces. It doesn't sound like a gust that caused that in my opinion, probably too much relying on trim down low to the ground. It could also have happened due in part to not applying enough back pressure after the mains touched and slamming the nose onto the rwy unintentionally and the plane coming back off rwy quickly. If you are stabilized and get the aircraft set up on final then you should have a profile that will work each and every time.

If you don't hold the nosewheel off the rwy then you will probably end up doing this on more occasions. Treat the next few landings as "soft field" and hold the back pressure in there and avoid the "bounce effect".

a few bounces do not make a "right"....

thats the weird thing...it wasn't a hard slam or bounce (not that I know what that feels like)...it was nice and smooooth down and up...next time around was nice...

anywho...thanks for the tip...I'll have to work on that soft field landing next time out...just need some x-winds...that seems to make it fun!

thanks again

Sounds good except, and I hate to say this because we all fly differently, try the same thing again with NO FLAPS.

I have never seen the need for using flaps UNLESS you have made a mistake on approach. Strong statement I know, but before you talk bad about me, try it for yourself. Yes I am a Flight Instructor. (Lrn2Fly)

Sounds like you induced some oscillations. Are you sure you didn't touch down a little nose-low? I've had students who bounced landings, only instead of re-flaring they shove the yoke forward to get back down. What follows is exactly what you describe.....bounce....bounce.....bounce....and the bounces get worse everytime unless a go around is initiated, they stop pushing forward on the yoke, or I take the controls.

Moral Of the story....don't forget to flare again after you bounce, if you're not gonna, please go around.

That sounds like what happened exactly...I got it down but it came back up...so I wanted to go back down, thought I flared (probably didn't) again and went back up...finally decided to go around...no way was I gonna get that thing down...in one piece...anyway yeah it was a nice smoooooth bounce though...not hard like I've felt before...

...anyway...thanks to every1 for responding...definately stuff I'll have to try...

Mini :

You need to find an instructor who knows how to teach landings.

What you described is a flat touch down at a speed that still produced a lot of lift, once you bounced you evidently used down elevator resulting in aggraviting the situation.

The bottom line is far to many instructors are ignorant of how to teach proper landings, generally the biggest problem is looking to far ahead during the period after the flare, if in fact there is a flare taught in the first place.

It is interesting that this poor teaching practice exists not only here in North America but also in Europe.

The most prevalent damage done to nose wheel airplanes in the accident reports in Britain is nose wheel damage...which is the result of poor training.

eh...I don't know if it is the instructor's fault...

...I'm the one flying the plane...and I did it before and for the checkride or I wouldn't have gotten signed off...no...I take the blame (not that I like that word...I am, afterall using my "license to learn") for the "bounce" and I'll put in the work to get rid of it....

...actually wanted to post to this thread tonight anyway but just wanted to say to all thanks for the help...tonight I had 3 GREEEEEEASERS...much better...probably just one of those things...

...feel like I made the right decision to go around instead of trying to get it down...then the next time was nice and smoooth...tonight all 3 were nice...so...I dunno...I'm gonna try not to worry about it...
