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 ATA10 Cessna 172 B2-L1 Flyable Storage    is a maximum of 30 days storage with no engine operation and/or the first 25 hours of  intermittent engine operation. Engine temperature and length of operation time are very important in the control of corrosion. The  desired flight time for air cooled engines is at least one continuous hour at oil temperatures of 165  degrees F (74 degrees C) to 200 degrees F (93 degrees C) at intervals not to exceed 30 days. The one  hour does not include taxi, take-off and landing time. T emperature gages must operate correctly.  The cooling air baffles must be in good condition and fitted properly.  The oil cooler system must be of the proper size for the engine and airframe installation. Oil coolers that  are not the correct size can cause an engine overheat condition or below minimum temperatures. Low  temperatures are as dangerous as high temperatures because of build-up o...
