5.5 GSU 75(), GRS 79
Figure 5-9 GSU 75() Installation (Sheet Metal Shelf Example)
NOTE
The GRS 79 has the same case and mounting hardware as the GSU 75() with the exception
of the Pitot-static ports, which are not present on the GRS 79. Removal and installation
procedures are similar for both units.
NOTE
Loosening of the unit mounting plate and/or the shelf to which the mounting plate is
attached requires re-calibration of the AHRS, which requires an installer unlock card.
5.5.1
