New GDC 74B Configuration Module Installed:
The correct configuration files must be loaded, if the GDC 74B configuration module has been
replaced.
Load the following files:
•
GDC1 Configuration
•
GDC2 Configuration
NOTE
Any pitot/static covers must be removed in order to successfully execute
the software and/or configuration loading to the GDC 74B.
7.1.6.1 GDC 74B Testing
NOTE
To avoid damage to the GDC 74(X), both the pitot and static ports must be
connected to the pressure control system. Throughout this procedure, ensure
that vertical speed does not exceed ±30,000 feet per minute. Ensure that
airspeed does not drop below
−
50 knots or rise above 450 knots. It is
acceptable to connect pitot and static ports together, using either the pressure
control system or external plumbing, so long as the leak specification of step 5
is met.
NOTE
Allow the unit to warm up for 15 minutes before performing the following tests.
Verification of the altimeter and airspeed must be performed using an air data test set (ADTS).
The static port and altimeter must be verified in accordance with Title 14 of the Code of Federal
Regulations (CFR) § 91.411 and Part 43 Appendix E. PFD1 must be in Configuration mode and
the MFD must be in Reversionary mode for performing the tests as outlined in Part 43 Appendix
E.
To prepare the G1000 System for Part 43 Appendix E testing:
Start the G1000 system in normal mode.
1.
Remove power to PFD1.
2.
Turn PFD1 on in Configuration mode by pressing and holding the ENT key on PFD1 while
applying power.
3.
Release the ENT key after “INITIALIZING SYSTEM” appears in the upper left corner of
PFD1.
