Pitot system supplies ram air pressure to ASI. Static system connects the VSI, altimeter, and ASI to atmospheric pressure through plastic tubing connected to a static port. 
Static line sump is installed at the source button to collect condensation in the static system. 
Heated pitot tube is standard, with the heating element controlled by a switch on the
instrument panel and powered by the electrical system. 
Alternate static source valve is installed on the instrument panel to use when the external static source is not in operation. 
            On airplanes with an autopilot, there is a tube that connects the autopilot to a static port on the left side of the airplane at FS 117.25. This part of the pitot/static system is not connected to the other parts of the pitot/static system.
          Correct maintenance of pitot and static system is essential for correct operation of altimeter, vertical speed and airspeed indicators, and, if installed, the autopilot. Leaks, moisture, and blockage can have an effect on the readings of the instruments. Under instrument flight conditions, you must use the instrument readings for the safe operation of the airplane. Keep the system clean and all instruments and all parts of the system correctly attached to the airplane. Keep the pitot tube and static ports clean with no blockage.
(1) Test the pitot/static system in accordance with the time limits.

VACUUM SYSTEM

By -
TTP B1-L3 ATA37 Cessna 172 B2-L2   V acuum system has a filter, vacuum gage, vacuum instruments, regulator valve, vacuum manifold,  low vacuum annunciator switches, engine-driven vacuum pumps and related plumbing.   With   Garmin G1000, the source of vacuum air is in the cabin and is pulled through the  system by the engine-driven vacuum pumps. This air goes through the gyro filter at the cabin inlet source  before it goes through the vacuum gage and gyro instruments. The vacuum is controlled by the regulator  valve. The regulator valve is on the aft side of the firewall. The vacuum air is then pulled through the  vacuum manifold and past the low vacuum annunciator switches and then into the vacuum pumps. Without Garmin G1000, vacuum pressure is measured by the low vacuum annunciator   switches in the engine compartment. The vacuum gage in the instrument panel shows the vacuum  pres...

TTP B1-L1 ATA08 Cessna 172 B2-L1             PTP Cessna 172 B1 LOC SGH B2 LOC SGH Required tools, equipment and materials-. Leveling Points Lateral Leveling. (1) Find two points that are the same on each upper door sill of the left and right cabin doors. (2) Put a level in position across these points. NOTE: Out-of-level tolerance for wing tips is three inches total. (3) Make a note of the airplane's lateral position. (4) If applicable, put jacks in position at the wings and tail jacking points. (a) Adjust the wing jacks as required to get the necessary lateral position. Longitudinal Leveling. (1) Find the two screws on the left side of the airplane tailcone that are in line with water line zero. (2) Remove the screws. (3) Install studs or long screws of applicable length (approximately two inches long). (4) Put the level...

           (1) Initial Inspecton _, inspect the fuel injector fuel lines and clamps between the fuel manifold and the fuel injector nozzles. Use MSB No. 342G,  to perform the inspection. Replace any fuel injector fuel line or clamp that fails the inspection required by the Fuel Line Inspection and Installation Checklist in MSB No. 342G.          (2) Re-inspect after any maintenance is done on the engine where any clamp on a fuel injector fuel line was disconnected, moved, or loosened, and within every 110 hours TIS and after each engine overhaul.
