Figure 4-21 Dual Horizontal G5 Recessed Installation - Garmin G5 Installation Manual

4.1.2.6.3 Recess Mounting Dual G5 Horizontally
In an installation where the G5 Attitude indicator is in the Turn Coordinator position and a G5 DG/HSI is
installed as well (ref Figure 4-21), the dual G5s may be installed recessed horizontally in a similar manner
to the dual vertical recessed installation. A horizontal recessed adapter plate will need to be field
fabricated in order to fit the existing installation. This plate must be fabricated of 0.090 thick 2024-T3
aluminum and must have some type of corrosion
protection (primer, alodine, etc.). A minimum of six No. 6, MS35206-2XX screws must be used to
secure the modified mounting adapter plate in place. Maintain 1.5D edge distance minimum.
