Cessna C172 Series, C172-M, N210AN, C172-N, C172-P Operation Procedure

Nice Air Operation Procedure Cessna 172

1

In The Beginning

• We have different models of C172:
C172-M (N210AN, N73454)
C172-N (N737TX)
C172-N with P-model engine (N213AN, N23AT, N739HE, N9568G)
C172-P (N212AN)

• C172-N with P-model engine is still N-model. Since it has modied according to STC, the P.O.H. has

supplemental Aircraft Flight Manual. Maximum weight, performance speed and operational procedure may
be different from original N-model.

• Check how many hours remains for next 100h inspection and check squawk before take airplane.

• Perform pre-ight inspection using check list. Report to the front desk if you need fuel, oil or found some-

thing need to be checked by mechanic.

• If the hobbs meter doesn’t much with the one in the tach sheet, report to front desk or instructor before start

the engine.

• Pull out the airplane with tow bar before start the engine. Use tow bar by one hand and pull the airplane by

other hand. After pull out, make sure tow bar is stored in the baggage compartment.

• Do not grab the dash board or post to adjust the seat position. Grab the bottom of instrument panel or win-

dow frame.

• Grab the window frame to close the door. Do not use the black strap to close the door.

• Use both hand to open the door. Sometimes the wind blow out the door.

• Do not put anything on the dash board. It will make scratch on the window shield and affect magnetic com-

pass deviation.

• After secure the seat belt and shoulder harness, put the remaining belt in between the legs.

• The toes must be kept at the bottom of the rudder pedal unless it is necessary to use the brake. Try to mini-

mize the use of the brake during taxi.

• Make tear drop entry and take #1 spot in run up area if possible to maximize the run up area.

• Before landing, make sure toes don’t touch the brakes.

• After landing, perform after landing check list.

• After come back to the parking, keep airplane parallel to the center line. DO NOT TURN in the parking

row.

• Use tow bar to park the airplane. NEVER push the tail and move the airplane. Instructor must help the

student to park the airplane.

• Use securing check list.

• If the hobbs meter stop in the middle of two numbers, take higher number.

• If you nd any deciency, make entry in the squawk sheet and report to the front desk.

Before Maneuver Check

1. Seat belt, harness-Fasten.

2. Fuel selector valve-On..

3. Mixture-Rich.

4. Carburetor heat-Off

5. Ignition switch-Both

6. Master switch-On

7. Primer-Lock

Clearing turn

Complete 90 degrees turn to the left, and 90 degrees turn to the right. Depend on the airspace and terrain,

right turn may be the rst. Watch the blind spot on the left, right, behind and below. Bank should be 15 to 20

degrees.

Slow Flight

Entry

1. Carburetor heat-On.

2. Throttle-1500 RPM, maintain altitude.
As you reduce power, you should anticipate pitch down and yaw to the right Don’t watch tachom-

eter needle to move from cruise to 1500RPM. Look at the horizon and cowling as you use peripheral

vision. Adjust control pressure to avoid nose from dropping and adjust rudder to keep the heading
constant.

3. Airspeed 80kt-Flap 10

70kt-Flap 20
60kt-Flap 30

The extension of ap cause nose to move up. If you allow it, you will gain altitude and airspeed

decreases too quick. Anticipate this and you need to add slight forward pressure on the control wheel

to avoid this. Watch horizon and cowling. Don’t x your eyes on the airspeed indicator and the ap
switch. After you set full ap, you need to apply back pressure to keep the altitude constant.

4. Airspeed 40kt-2000 RPM
Add right rudder as you add power to compensate the left turning tendency. PTS require you to main­tain minimum controllable airspeed which is almost 35kt for C172. However, you need to be able

to y at any speed. Use trim. After this point, generally, pitch controls airspeed and power controls
altitude. Remember the pitch attitude which gives you 35 kt.

Climb

Apply full power. Adjust pitch to maintain the airspeed. Add right rudder to maintain the heading. For level
off, reduce power necessary to maintain the altitude. Adjust pitch to maintain the airspeed.

Descent

Reduce power as necessary. Adjust pitch to maintain the airspeed. Reduce right rudder to maintain the head­ing. For level off, add power necessary to maintain the altitude. Adjust pitch to maintain the airspeed. Add
right rudder to compensate the left turning tendency.

Turn

Use 10 degrees bank. For the right turn, you need to use more right rudder because of the left turning tenden-

cy. On the other hand, the left turn dose not require much left rudder. Just reduce right rudder a little bit.

Recovery

1. Throttle-Full, maintain the altitude.
Add right rudder to compensate the left turning tendency. Adjust pitch “gradually” to maintain the alti-

tude. Don’t push nose down quickly. Pitch should be changed slowly from slow ight attitude(high) to

cruise attitude(level). Look at the horizon and cowling as you scan the altimeter.

2. Carburetor heat-Off, Flap-20

3. Airspeed 60kt-Flap 10

4. Airspeed 70kt-Flap Up

The ap retraction cause the nose to move down. You need to anticipate and add back pressure as

necessaryto maintain the altitude. As airspeed increases, you don’t need much right rudder anymore.

Reduce right rudder as needed.

5. Airspeed 80kt-Throttle CruiseReturn to cruise ight. Use trim.

Power Off Stall

Entry

1. Carb heat-On

2. Throttle-1500 RPM
Maintain altitude

3. Airspeed 80kt-Flap 10

70kt-Flap 20
60kt-Flap 30

1 through 3 are same as slow ight.

4. Start descend at 60 kt

5. Throttle-Idle Increase back pressure to keep altitude to reach stall.

If you do this too gentle, it will not stall because the airow over the elevator is too slow to create

enough tail down force to cause stall.

Recovery

1. Release back pressure.
You don’t need to push nose down too steep.

2. Throttle-Full, Maintain level ight attitude.
Don’t look inside the cockpit. Your right hand is already on the throttle. Just move it forward. Look
horizon and cowling. Adjust control pressure to establish level ight attitude.

3. Carb heat-Off, Flap-20
After retract the ap to 20, return your right hand on the throttle. Wait for the airspeed to increase as
you maintain level ight attitude.

4. Airspeed 60kt(Vx), Climb attitude
Look at horizon and the cowling to establish normal climb attitude. And wait.

5. Positive climb-Flap 10

Avoid pitch change caused by ap retraction.

6. Airspeed 73kt(Vy)-Flap Up

7. Level off, Airspeed 80kt-Throttle Cruise

Power On Stall

Entry

1. Carb heat-On

2. Throttle-1500 RPM
Maintain altitude

3. Airspeed 55kt-Throttle Full, Carburetor heat-Off, Climb attitude (slightly higher than normal climb at-

titude)

No need to pull nose up very high. If the nose is too high, it will drop a lot and lose excessive altitude
after stall. To avoid this, maintain the pitch slightly higher than normal climb attitude at which air­speed is decreasing gradually(about 15 degrees up). Add back pressure to keep this pitch attitude con­stant as airspeed decrease. Look at the horizon on the both side of the cowling to judge your attitude.
Also, add right rudder as airspeed goes down to keep coordinate.

Recovery

1. Release back pressure

2. Maintain level ight attitude.

Release back pressure gently to return to the level pitch. Wait for the airspeed to increase.

3. Airspeed 60kt(Vx), Climb attitude

4. Positive climb-Airspeed 73kt(Vy)-Level off.
Since the power on stall is the simulation of the departure stall, the altitude you begin this maneuver is
the airport elevation. During recovery, you shouldn’t go below the original altitude. If you do so, that

mean you crash on the ground. You should nish this maneuver at higher altitude than you begin.

5. Airspeed 80kt-Throttle Cruise
