Garmin G5 Installation Manual page 73

The G5 has two ports that are connected to the aircraft's pitot and static pressure sources. The ports are
labeled on the unit using the abbreviations "P" and "S" respectively (Figure 6-13). The pressure ports
have 1/8-27 ANPT female threads. The mating fitting must have 1/8-27 ANPT male threads.
Determine the hose/connection material that best interfaces with the existing aircraft installation.
Reference the appropriate aircraft parts manual to determine the current part numbers associated with
the aircraft installation of hose and connections used in the pitot/static system.
Use appropriate tubing and fittings to connect the pitot and static lines to the unit. Avoid sharp bends in
the tubing and route hoses clear of aircraft control cables. The G5 must not be at the low point of the
pneumatic plumbing lines to avoid moisture or debris collecting at or near the unit. Ensure that no
deformations of the airframe surface have been made that would affect the relationship between static air
pressure and true ambient static air pressure for any flight condition. Refer to 14 CFR Part 43, Appendix
E and AC43.13-1B, Chapter 12, Section 4 for approved practices while installing hoses and connections.
If this static source had an alternate static source selector switch, it must be retained.
For aircraft equipped with a single pitot-static system, the G5 must be connected to the pitot-static
system used by the pilot's instruments. For aircraft equipped with a dual pitot-static system, the G5 must
be connected to the pitot-static system that is independent from the pilot's instruments.
CAUTION
To avoid damaging the G5 pressure sensors, both the pitot and static ports must be connected to
the test set.
CAUTION
Verify sealant/tape is not present inside the plumbing upon assembly. Use care to avoid getting
fluids or particles inside the pneumatic lines or G5 ports.
