Brakes. (press briefly to check for pressure)

Oh, and Master On, Mags Both. It never hurts to be sure.

The full 152/172 landing checklist, as I've learned it:

Master On
Mags Both
Carb Heat On
Mix Rich
Fuel Switch On (or to Both in the 172)
Brakes
Land...

You land with the carb heat ON?

Well I've got about five seconds on you...

I do a BUMPS while downwind: Brakes, Undercarriage (who cares if it's
fixed or not, this is good practice, and the club has a C172-RG (kinda
need it then)), Mixture/Mags/Primer pump and tanks both, Pitch fine (ok,
still good practice, Secure? (belts, door latches).

Before pulling the throttle at the end of downwind it's carb heat on.

Turning final, carb heat back off. (Any probs in the land, or even
after landing that might necessitate a go round, I'm ready for full
throttle - no messing around with the carb heat).

That's probably the only thing on the list required by regulation:

Yeah, that's my point. Who takes them off?

I do. They wrinkle my dress.

These guys are probably the same ones that tell you that since it's a
school plane, you can use the "abbreviated preflight checklist" and just
check for fuel and oil before going up.

If your students never plan to fly any plane besides the one that they were
trained it, it MIGHT be OK to abbreviate the checklist to cover only those
items that are "applicable" to their plane.

But if you want to train someone to be a good pilot, you build good habits,
which may include checking things that are easy to "assume".

JMHO..

How many people do / teach doing a full before landing checklist when
doing pattern work? I do with my students, but other cfi's I work with
use a quick / abbreviated one for our Cessna 172/152

You can check the brakes for even pressure and turn your landing light on.

Your 10-year old in the back seat does. That's probably why the FARs
require this. Some DE will flunk you on a check ride if you neglect to
verify seat belt usage before landing.

Doing it your way, you may find that full throttle produces little power because
the carb could be iced up. Check your POH. I believe you will find it specifies
the use of full carb heat any time RPM is reduced below the green arc on the
tach. There is a reason for this, especially on O-200 and O-300 powered Cessnas.

Let me assure you that most folks without a crippled hand can push the throttle
and carb heat on a Cessna forward at the same time if need be. If physically
unable, go to full throttle and then turn carb heat off. Full throttle with carb
heat on will still get you enough power to go around (unless you are in a C-150
and have 40 degress of flaps down), especially considering you will have the
carb heat off in about 2 more seconds.

Best regards,

My Cessna provided pilot's operating handbook checklist for a 1959
C-172 reads as follows:

J. BEFORE LANDING.
(1) Set fuel selector to "Both".
(2) Recheck mixture "Full Rich" (full in).
(3) Apply carburetor heat before closing throttle.

Of course this was before the FAA seatbelt regulation which added
to later models a "Seatbelts ON" item.

A commercially available C-172 N model checklist from AVTECH PILOT
PRODUCTS reads as follows:

BEFORE LANDING CHECKLIST
Seats/Seatbelts............Secure
Fuel Selector..............Fullest Tank/Both
Carburetor Heat............ON
Mixture....................Rich/As Required

I've spent about six years landing with the carb heat ON.

Full throttle with carburetor head applied is also likely to cause
detonation due to an excessively lean mixture. This preignition
applies all the instantaneous force of the _exploding_ (as opposed to
burning) gasoline/air mixture directly against the top of an ascending
(not descending as normal) piston. Detonation can bend piston rods or
crack the case. Over a longer period of time, detonation can burn
through the top of aluminum pistons.

Since WHEN does carb heat LEAN the mixture???:
Carb heat reduces the density of the intake air and therefore ENRICHES
the mixture.

Oops. You are correct. Hopefully, you found no other errors in my
comments.
