Some of the procedures I have learned
My Checklist for Cessna 172R or S

Steps for proper landing
Reduce power to 2000 RPMs on the downwind.
At the numbers, reduce power to 1500 RPMs, put in the first 10 degrees of flaps, and trim the plane for level flight.
When I turn onto base, put in the next 10 degrees of flaps.
After turning onto final, adjust power to make the runway. Put in or take out as needed.
When I am sure I have the runway made, put in the last 10 degrees of flaps and reduce power.
When about 1 wingspan from the ground, pull back on the yoke and hold the plane off the ground while my speed decreases.
When the plane's main wheels touch down, keep holding the yoke back and let the nose wheel lower slowly.
When the plane is on the ground, maintain control and slow the plane by applying the brakes.
If it is a touch and go, rather than slowing, put the flaps all the way up and apply full power.
When back up to speed, gently pull back on the yoke and climb away.

Stalls - Done at or below Maneuvering Speed (99 KIAS)

Power Off
1900 RPMs and Full Flaps

Pull power
Hold Nose up
Pull back on yoke
At break, Full power
Climb Attitude
10 degrees flaps out
Climb
Remove remaining flaps slowly

Power On
2000 RPMs

Pull back on yoke
At break, nose over to horizon
Full power
If wing breaks either way, reduce power, push nose over to avoid secondary stall and slowly pull out and climb
Crosswind Calculation
There is a relatively simple rule of thumb that can be used to get a rough idea of the crosswind component

To do this, you only have to remember three numbers: 30, 45, and 60.

If the wind is 30º off the runway heading, then the crosswind component will be half the wind speed;
at 45º it will be about two-thirds of the wind speed;
at 60º the crosswind component is almost nine-tenths of the wind speed.

To handle the angles in between, use a simple proportion for angles less than 30º.

For example, at 15º off the runway heading, the crosswind component is about half the value at 30º,
and this makes for about one quarter of the wind speed.

Between 30º and 45º, use the value for 45º, or two-thirds of the wind speed.

Above 45º but below 60º, use nine-tenths of the wind speed.

Above 60º, use the full wind speed.

Pattern Procedures in 172RG

At Takeoff - Carb Heat Off, Cowl Flaps Open, Full Power
When No Useful Runway Left and Positive Rate of Climb - Tap brakes and Gear up
At 500' AGL - 25" Manifold Pressure and 2500 RPMs, 25^2
At TPA - 20" Manifold Pressure, 2400 RPMs, and Cowl Flaps Closed
Midfield - Below 140, Gear Down, 10 degrees of Flaps, Check for Green Light and Gear in Windows
At the Numbers - 15-17" Manifold Pressure, Carb Heat On, 80 Knots
On Base - 20 degrees flaps, Check for Green Light and Gear in Windows, 70 Knots
On Final - Full flaps, Check for Green Light and Gear in Windows, Prop Full Forward, 60 knots
After Touch Down - Flaps Up, Cowl Flaps Open

Radio Communications
Uncontrolled field radio procedures:
Approximately 10 miles out: [Field Name] Traffic, [Plane Call Sign], to the [Direction] descending through [Altitude] for [Intended activity - touch and go, landing full stop, fly over, etc.], [Field Name] Traffic

At 3 miles: [Field Name] Traffic, [Plane Call Sign], to the [Direction], on [Position - downwind, crosswind, etc.], for [Intended activity] on Runway xx, [Field Name] Traffic

In the pattern: [Field Name] Traffic, [Plane Call Sign], on [Position - downwind, base, final], for [Intended activity] on Runway xx, [Field Name] Traffic
If planning touch and go, state intended departure direction.

On Takeoff: [Field Name] Traffic, [Plane Call Sign], airborn off of Runway xx, [Intended Activity], [Field Name] Traffic
If leaving area, state intended departure direction.
If staying in the pattern, state left or right traffic.

Communication with Approach Controller
Dial in and get current weather information.
About 20 miles out, call the approach controller.
[Field Name] Approach, [Plane Call Sign] about [Distance] miles to the DIRECTION from airport, requesting Class [B or C Services], inbound for [Planned Activity].
If planning a touch and go, state direction of departure on the go.

When Approach Control replies, they should give a sqawk code and possibly vectors.

Acknowledge their reply and sqawk code.
[Field Name] Approach, [Plane Call Sign] sqawking [Code].

Communication with Departure Controller
[Field Name] Departure, [Plane Call Sign], airborn off [Runway], departing to the [Planned Direction]

They should acknowledge the call and give me a vector to fly and a sqawk code.

[Field Name] Departure, [Plane Call Sign], departing at [Vector]

15-20 miles from airport, if Departure has not released, call [Field Name] Departure and ask to be released.
If released, and authorized to change frequencies, acknowledge and switch transponder to 1200.

Transitioning Airspace
Since I had taken off of runway 35, I had to do a left turn back to the south. I headed to the river and switched over to Downtowns ATIS and got their weather. It was essentially the same as Alton.

I started listening to their TOWER and am amazed at how busy they are. At about 10 miles, I found a hole in the almost constant Tower traffic and told them:
Downtown Tower, Cessna 2725A, 9 miles to the North, I would like to transition through your area and follow the river to the South.
They cleared me to pass and gave me a new altimeter setting so I could make sure my altimeter was set properly.

When I was about 10 miles south of Downtown, I called them and told them I was clear of their airspace. They thanked me and told me to have a nice day.

Flight Following:
XX Approach (STL 124.2), Cessna XXX airborn off Regional with request.
When Approach replies, tell them:
Climbing thru yy for zz to Destination. Request Flight Following.
They should respond with a squawk code.
Reply "squawking [CODE]".
If workload allows, they should respond with "Radar Contact" and a position report.
If position correct, reply "Confirm."
They will watch for you and give traffic advisories.

Radio Navigation
VOR Navigation:
Set radio to appropriate frequency.
Listen for Morse code and confirm proper VOR.
Turn OBS until TO flag shows and neddle is centered.
Turn to heading indicated by OBS markings.

NDB:
Set radio to appropriate frequency.
Listen for Morse code and confirm proper VOR.
Set OBS and turn to heading indicated by arrow.

Misc
Traffic Distances:
Crosswind: after reaching 1,000 feet
Downwind: 3/4 mile from field
Base: when runway shows 45 degree behind plane - Should start at 1,400 feet and end at 1,000 feet. (At ALN)
Final: about 3/4 mile from end of runway

E6B Usage:
Fuel used: Set 60 on inside wheel to Burn rate (9 mph in 172s)
Find time needed on middle wheel. Look at fuel used on outer wheel.

Distance/Time: Set 60 on inside wheel to Ground Speed on outer wheel.
Find time needed on middle wheel. Look at distance covered on outer wheel.

What to do in case of emergency
P - Persperate
A - Aviate
N - Navigate
I - Investigate
C - Communicate
