detection due to power sequencing issues between different power sources or when the
backup supply is not used. The HIS power supply status is always available on the Input
Discrete Status Label.
This setting is selected based on the use of the HIS and whether the built-in test is required
to monitor the power input.
(3) Synchronized Approach Selection
When On, the GLSSUs will propagate the approach selection on the GLS bus using the
FASDM and accept it on the X-Talk input. This APD also allows other labels to be re-
transmitted from the X-Talk input to the GLS bus. Refer to subsection 1.2.3 in Appendix A
for X-talk connection details.
When Off, the GLSSUs are independent and labels will not be re-transmitted on the GLS
bus.
This setting is used to select whether the approach selection is done independently on all
GLSSUs in the system (either by the operator or automatically by the FMS) or whether the
GLSSUs themselves perform this synchronization function.
(4) Reset on Critical Fault
When On, the GLSSU will reset after entering Fault mode.
When Off, the GLSSU will remain in Fault mode until the fault is no longer present.
This setting is used to control whether the GLSSU automatically attempts to recover from
Fault mode. It is used mostly when the initiated BITE is not available or when a separate
breaker is not available to restart the unit. The impact on downstream equipment of a
continual cycle of resets during a permanent fault must be considered.
(5) Navigation Center Position Output on GLS bus
The outputs of type “GPS bus” always report the GPS antenna position; this APD affects
only outputs of type “GLS bus”.
When On, the position output labels correspond to the aircraft navigation center position
except under the following conditions, where the antenna position is selected:
- Attitude Data Used APD is On but no attitude data available; or
- Attitude Data Used APD is Off but no approach is selected (FAS Runway Heading not
available); or
- SDI dependent APD parameters are not defined for the GLSSU SDI setting.
The Navigation Center is the point on the aircraft used to compute the deviations from the
glide path and the distance to the runway threshold (LTP/FTP).
There is no direct indication on any ARINC 429 output label on the type of position output
provided. However the state of approach selection and attitude input bus activity (IRS/FMS
inputs) is available on the ARINC 429 output.
When Off, the position output labels correspond to the GPS antenna position.
