The GRS 77/7800 AHRS and GMU 44 Magnetometer do not have a configuration file. However, the
GRS 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 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 7400 air data computer configuration file is loaded directly to GDC 7400 internal memory and
there is no configuration module for the GDC 7400.
