    Unit Installation 1.3.3.2 ADDITIONAL EQUIPMENT REQUIRED A 3/32” hex drive tool is required to secure the G5 to the panel as described in Section 1.3.6.3 and shown in Figure 1-15. Air hoses and fittings are required to connect pitot air and static air to the G5. The G5 uses a female 1/8-27 ANPT fitting for each of these ports.
  • Page 38 • Mount the G5 with the connector aligned to within 1.0° of the longitudinal axis of the aircraft (display bezel parallel to the wing spar). Do not install the G5 in a panel that is angled to the left or right with respect to the wing spar.
  • Page 39 1/8-27 ANPT male threads. NOTE: The temporary port plugs attached to the pressure ports on a new G5 are not suitable for flight and must be removed prior to the installation of G5 into the aircraft.
  • Page 40 Avoid sharp bends in the tubing and attempt to route hoses away from aircraft control cables. The G5 should 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.

  • Page 41: Antennas

    NOTE: Use of different colored tubing is recommended for static and pitot plumbing to avoid plumbing connection errors. Incorrect plumbing connections will result in erroneous air data information calculated by the G5. Observe the following cautions when connecting pneumatic lines:...

    A GPS 20A (and connected GPS/WAAS antenna) can be used as the sole GPS source for a G5 system, however it is recommended to also install a GPS antenna on a G5 or GDU 37X/4XX for redundancy. If the G5's GPS receiver is not used in a particular installation, it may be disabled in configuration mode (see Section 1.8.4.11).

  • Page 51: Garmin Antennas

    NOTE: See the G3X/G3X Touch Installation Manual (190-01115-01) for detailed GPS antenna installation information. All antenna mounting and unit installation recommendations applicable to the GDU37X/4XX also apply to the G5. NOTE: It is the installer’s responsibility to ensure that their choice of antenna meets FAA standards according to the specific installation.

  • Page 105 GSA 28 installation that controls only the roll axis is sometimes referred to as a “wing-leveler”. The roll servo follows roll steering commands from the G5 so the airplane will hold a desired roll angle, follow a desired heading/track, or follow the lateral component of a flight plan.
  • Page 106 Most GSA 28 autopilot systems consist of both a roll and pitch servo allowing for full 2-axis control of the aircraft. The pitch servo follows vertical guidance commands from the G5 so the airplane will hold a desired pitch angle, vertical speed, airspeed, or altitude, or follow the vertical component of a flight plan.
