Systron Donner Inertial (SDI) has uncovered a potential fault in the MMQ-G system software that manifests itself when using the MMQ-G
in Air Alignment mode. If a satellite dropout occurs during Air Alignment mode, a flaw in the MMQ-G software logic can result in system
level performance that does not meet specification when the unit transitions to the navigation mode. This problem ONLY occurs if a
satellite dropout occurs during Air Alignment Mode. All other operational scenarios are NOT affected and operate as specified.
