landing a 172
Hi,
I'm not sure what the problem might be on your landings in the C172, it is quite the same as the c152, just a little bigger. Just a few pointers:
Make sure your seat is adjusted so that you can see above the airplane's nose.
On final, make sure that you have the correct airspeed (1.3 Vso tends to work) or you can use 5kts extra.
As you approach final, and your landing target moves under the airplane's nose, don't pitch the nose down, instead start using your peripheral view to get the feeling for height, and about 100 ft from the runway start bringing the power to idle.
To start the flare, look at the end of the runway, you'll see a visual effect that the end of the runway is sloping up, just follow it as you flare.
And the last thing that used to work for some of my students, just try to fly the airplane off the runway in ground effect, hold the pitch and use some throttle, you will end up making the best landing ever.
Good luck and talk to your instructor
