The GRS 77 AHRS and GMU 44 Magnetometer do not have a configuration file. However, the GRS77
does store calibration data acquired during the post installation checkout, which are characteristic to the
specific installation. A copy of this calibration data is stored in the GRS 77 configuration module. While
performing maintenance on these units, re-calibration may be required. See Section 7.7.1 for more
information on re-calibration criteria.
The GDC 74B air data computer configuration file is loaded directly to GDC 74B internal memory. A
copy of the file is stored in the GDC 74B configuration module.
The GDC 7400 air data computer configuration file is loaded directly to GDC 7400 internal memory and
there is no configuration module for the GDC 7400.
