CESSNA SECTION 4 MODEL 172S NAV III NORMAL PROCEDURES GFC 700 AFCS AMPLIFIED NORMAL PROCEDURES PREFLIGHT INSPECTION The preflight inspection, described in Figure 4-1 and adjacent checklist, is required prior to each flight. If the airplane has been in extended storage, has had recent major maintenance, or has been operated from rough runways, a more extensive exterior inspection is recommended.
Page 142 SECTION 4 CESSNA NORMAL PROCEDURES MODEL 172S NAV III GFC 700 AFCS PREFLIGHT INSPECTION (Continued) Outside storage for long periods may result in dust and dirt accumulation on the induction air filter, obstructions in airspeed system lines, water contaminants in fuel tanks, and insect/bird/rodent nests in any opening.
Page 143 CESSNA SECTION 4 MODEL 172S NAV III NORMAL PROCEDURES GFC 700 AFCS STARTING ENGINE In cooler weather, the engine compartment temperature drops off rapidly following engine shutdown and the injector nozzle lines remain nearly full of fuel. In warmer weather, engine compartment temperatures may increase rapidly following engine shutdown, and fuel in the lines will vaporize and escape into the intake manifold.
Page 144: Starting Engine
SECTION 4 CESSNA NORMAL PROCEDURES MODEL 172S NAV III GFC 700 AFCS STARTING ENGINE (Continued) RECOMMENDED STARTER DUTY CYCLE Operate the starter motor for 10 seconds followed by a 20 second cool down period. This cycle can be repeated two additional times, followed by a ten minute cool down period before resuming cranking.
Page 145: Fuel Vapor Procedures
CESSNA SECTION 4 MODEL 172S NAV III NORMAL PROCEDURES GFC 700 AFCS FUEL VAPOR PROCEDURES The engine fuel system can cause fuel vapor formation on the ground during warm weather. This will generally occur when the outside ambient air temperature is above 80°F. Vapor formation may increase when the engine fuel flows are lower at idle and taxi engine speeds.
Page 146: Taxiing
SECTION 4 CESSNA NORMAL PROCEDURES MODEL 172S NAV III GFC 700 AFCS TAXIING When taxiing, it is important that speed and use of brakes be held to a minimum and that all controls be utilized, refer to Figure 4-2, Taxiing Diagram, to maintain directional control and balance.
Page 147 CESSNA SECTION 4 MODEL 172S NAV III NORMAL PROCEDURES GFC 700 AFCS TAXIING (Continued) TAXIING DIAGRAM NOTE Strong quartering tail winds require caution. Avoid sudden bursts of the throttle and sharp braking when the airplane is in this attitude. Use the steerable nosewheel and rudder to maintain direction.
Page 148: Before Takeoff
SECTION 4 CESSNA NORMAL PROCEDURES MODEL 172S NAV III GFC 700 AFCS BEFORE TAKEOFF WARM UP If the engine idles, with the throttle against the idle stop, (approximately 675 RPM) and accelerates smoothly, the engine is warm enough for takeoff. Since the engine is closely cowled for efficient in-flight engine cooling, the airplane should be pointed into the wind to avoid overheating during prolonged engine operation on the ground.
Page 149: Elevator Trim
CESSNA SECTION 4 MODEL 172S NAV III NORMAL PROCEDURES GFC 700 AFCS BEFORE TAKEOFF (Continued) ELEVATOR TRIM The elevator trim tab is in the takeoff position when the trim pointer is aligned with the index mark on the pedestal cover. Adjust the trim wheel during flight as necessary to make control wheel forces more neutral.
Page 150: Wing Flap Settings
SECTION 4 CESSNA NORMAL PROCEDURES MODEL 172S NAV III GFC 700 AFCS TAKEOFF (Continued) WING FLAP SETTINGS Normal takeoffs use wing flaps UP - 10°. Using 10° wing flaps reduces the ground roll and total distance over an obstacle by approximately 10 percent.
Page 151: Enroute Climb
CESSNA SECTION 4 MODEL 172S NAV III NORMAL PROCEDURES GFC 700 AFCS ENROUTE CLIMB Normal enroute climbs are performed with flaps up, at full throttle and 75 to 85 KIAS for the best combination of performance, visibility and engine cooling. The mixture should be full rich during climb at altitudes up to 3000 feet pressure altitude.

After engine start and for all ground operations, set the throttle to 1200 RPM and lean the mixture for maximum RPM.
Page 158: Stalls
SECTION 4 CESSNA NORMAL PROCEDURES MODEL 172S NAV III GFC 700 AFCS STALLS The stall characteristics are conventional and aural warning is provided by a stall warning horn which sounds between 5 and 10 knots above the stall in all configurations. Power off stall speeds at maximum weight for both forward and aft C.G.
Page 159 CESSNA SECTION 4 MODEL 172S NAV III NORMAL PROCEDURES GFC 700 AFCS SPINS (Continued) It is recommended that entries be accomplished at high enough altitude that recoveries are completed 4000 feet or more Above Ground Level (AGL). At least 1000 feet of altitude loss should be allowed for a 1-turn spin and recovery, while a 6-turn spin and recovery may require somewhat more than twice that amount.
Page 160 SECTION 4 CESSNA NORMAL PROCEDURES MODEL 172S NAV III GFC 700 AFCS SPINS (Continued) Regardless of how many turns the spin is held or how it is entered, the following recovery technique should be used: 1. VERIFY THAT THROTTLE IS IN IDLE POSITION AND AILERONS ARE NEUTRAL.
Page 161: Landing
CESSNA SECTION 4 MODEL 172S NAV III NORMAL PROCEDURES GFC 700 AFCS LANDING NORMAL LANDING Normal landing approaches can be made with power on or power off with any flap setting within the flap airspeed limits. Surface winds and air turbulence are usually the primary factors in determining the most comfortable approach speeds.
Page 162: Crosswind Landing
SECTION 4 CESSNA NORMAL PROCEDURES MODEL 172S NAV III GFC 700 AFCS LANDING (Continued) CROSSWIND LANDING When landing in a strong crosswind, use the minimum flap setting required for the field length. If flap settings greater than 20° are used in sideslips with full rudder deflection, some elevator oscillation may be felt at normal approach speeds.
Page 163: Cold Weather Operations
CESSNA SECTION 4 MODEL 172S NAV III NORMAL PROCEDURES GFC 700 AFCS COLD WEATHER OPERATIONS Special consideration should be given to the operation of the airplane fuel system during the winter season or prior to any flight in cold temperatures. Proper preflight draining of the fuel system is especially important and will eliminate any free water accumulation.

SECTION 4 CESSNA NORMAL PROCEDURES MODEL 172S NAV III GFC 700 AFCS COLD WEATHER OPERATION (Continued) STARTING When air temperatures are below 20°F (-6°C), use an external preheater and an external power source whenever possible to obtain positive starting and to reduce wear and abuse to the engine and electrical system.
