Pulled my logbook tonight. Took me 4 hours, 3 lessons to transition to a 172 after my PP CR.
The passenger thought the landing was "great".
Flew the 172 tonight (after 10pm) next to the Golden Gate Bridge. So much more comfortable than the 152 with a "normal" to "larger than normal" sized adult male (is 230 normal?)
I used pillows in certain places to improve my sight picture (under me) and my rudder control (behind me). I was awash with pillows but my landing was really good. Remembered to just "hold it off, hold it off" with a lot more force than that little 152 yoke requires.
The passenger thought the landing was "great". Though he had only been in one or two other small planes before. I was so relieved.
Asking for opinions... I was riding in the back of a 182, and after a nice landing, the pilot held off the nose, but kept increasing the back pressure, and then the nose came down, hard, although the pilot didn't let go.
I'm assuming the elevator stalled.
I can see where if the same elevator angle of attack is maintained on the rollout, the nose will come down gently as speed (and lift) decrease. But if one continues to increase the Elevator AoA, you can stall it which will result in a "bang".
So, is the proper technique (during the rollout):
To just hold the elevator where it was for the touchdown, and let the nose come down as you slow down.
Positively and gently "fly" the nose down by releasing back pressure
Increase back pressure to maintain the nose-up attitude?
The Arrow is guilty of this, much moreso than the 182 I fly. It kind of glides like a piano to begin with, but the tail stops flying at a very specific speed, and when it does the nose will be on the ground. I really wish that airplane had more elevator effectiveness, when I touch down I am at almost full travel on the elevator, doesn't leave much control surface to keep the tail flying long enough to lower the nose.

There are three simple rules to making perfect landings. Problem is, no one knows what they are.
Don't sweat it, kiddo. I remember a flight with a high-time IFR pilot where I thought he'd broken the airplane. Seriously, gave me a LOT of respect for Skylanes. If the plane survived and it didn't feel like you broke anything, you're doing just fine.
Funny, I had a similar experience on my Commercial ASEL addon. I had been flying tons of Piper singles and alot of twins leading up to it. I had just breezed through my Comm AMEL checkride a few days before and was doing the SE addon in a 172......went up with the instructor and we did all the commercial maneuvers with no trouble. Then came back to practice the landings. Holy cow did I suck! I mean, I've seen 1st time solo students who could land a 172 better than I was doing....it was unreal. Took me a couple flights to get the hang of it, but now I am as comfortable in 172 as any Piper or Beech.For what it's worth, my landings in a 172 were always turds after I'd been flying my Arrow or other low wing airplanes due to the reduced ground effect and long glide ratio (an Arrow drops like a rock once the gear comes down.)
Thanks. I still wish all my landings were "perfect" but I appreciate the feedback.

Also 172's are more stable airplanes than 152's, meaning you have to muscle them around a bit more to make them do what you want to do, like for example proper landing flares. Just like any other plane you get used to them though.
FWIW, while 50F ROP is where a lot of POHs and people recommend running an engine, it's actually about the most abusive, creating the highest peak pressures inside cylinders as well as the highest CHTs. Typically that's not a big issue with the engines in a 172 since they're pretty robust and relatively low power. But when you get to airplanes with bigger engines it's not a good idea to operate them that way so you might not want to get in that habit. When you run out of more important things to learn aviation wise there's a lot of good info about aircraft engine management on the internet.PS - Learned how to lean the mixture to 50 degrees rich of peak using a new instrument called an EGT.
It should be there on the 152 but it wouldn't surprise me if it was broken. IIRC, it's a T-handle you pull out and twist but I could be mis-remembering. On some airplanes you operate a valve while pressing on the on the brake pedals to set the parking brake.Oh and learned how to use a parking brake - either the 152 doesn't have one or it is broken, since we've never once used it.
Agreed. I only wanted to plant the "proper engine management" seed for future equipment upgrades.Hey, for a normallly aspirated O-360 or O-320 that's going over TBO no matter what you do, it's just fine.
Pushing 350 hours TT and I wish all my landings were "perfect", too. I save my worst ones for PWT so the people at the cafe have something to talk about.
One of my worst landings in years was my -- umm -- "arrival" at Windwood last October.
I planned on landing on 24 but those trees seemed awfully close to the approach end. So I went around for 6 (winds were light and variable).
I thought I had it all set, tail wheel rolling, when suddenly I'm airborne again -- I reverted to training and held the yoke all the way back and dropped it in from about 3' AGL.
Fortunately, I landed on the first third of the runway. Houses blocked the view from the restaurant balcony.
It happens. It happens less often when you're flying the same airplane from the same seat frequently.
Last year I used all 3000 feet of that runway for landing. Had it been 2900 I would have had an excursion. The only thing scarier was my departure. Gave me some serious respect for the mountains.
The morning of my check ride, my instructor covered every flight instrument, all of them, except for the engine monitoring instruments. We did touch and goes, full stops, all the maneuvers, everything, with no instruments. My landings and all my flying improved tremendously.

Airspeed indicator as well?
You don't need airspeed to fly safely in VMC, day or night. You can tell how fast you're goin by sink rate and control responsiveness
Had ASI covered on many flights ... sight picture for landing and Tach at 1700 abeam the numbers. Came in handy one week after PPL when it actually failed.
I would argue that "sight picture" or RPM really can substitute ASI
Airspeed indicator as well?
The FARs don't say what's necessary to fly safely, they say what's needed to fly legally.You do according part 91.205
Power, Attitude, Configuration = Performance.I would argue that "sight picture" or RPM really can substitute ASI
PS -
Found out the throttle lock on the 172 is sort of unscrewing in a weird way, the gas gauges sort of shake, and I am not at all used to the trim. But little things, little things. Oh and I accidentally reclined my seat, so many knobs and adjustments! It is like a limo compared to my no frills 152
LOL! That all sounds familiar. Those seats drove me nuts at first. And it does take a while to figure out how much to turn the trim wheel.
Some advice: NEVER trust those Cessna fuel gauges. More than one more experienced pilot has warned me that they are only accurate when the tanks are full or empty, and I have verified this myself. Best to ignore them.
ALWAYS verify how much you have before you depart (by sticking the tanks or whatever method), and know the plane's fuel burn rate. It's a habit that cwill serve you well with just about any plane, even one with better gauges (no system is perfect, even a good ol' cork with a wire through the filler cap).
Hey that's good...the only requirement for fuel gauges that the FAA has is that they be accurate when empty!Some advice: NEVER trust those Cessna fuel gauges.

It's a short field landing, forget grace, plop in on and get on the binders. :wink2:The one that bugs me the most is short-field stuff where you land nose-high and then *have* to get on the brakes immediately and aggressively. That'll rotate the nose down *right now* and plop it on pretty good. I can't modulate the brakes lightly enough during that initial braking to not "bump" the nose gear down.
Dunno. Maybe I just need more practice.
