Aircraft Signaling
The WQAR supports two different aircraft signaling types with their
accompanying speeds:
BI-POLAR:
In addition to the standard hard-coded 64, 128,
256, 384,512, 1024, and 2048 WPS rates, the WQAR
supports AUTO mode where it dynamically determines the
rate of the signal as it is coming in. It also supports a
DISCRETE mode where, during bootup, it determines the
speed by monitoring speed discretes activated from the
acquisition unit.
BI-PHASE:
In addition to the standard hard-coded 64, 128,
256, 384, 512, 1024, and 2048 WPS rates, the WQAR
supports AUTO mode where it dynamically determines the
rate of the signal as it is coming in. It also supports a
DISCRETE mode where, during boot up, it determines the
speed by monitoring speed discretes activated from the
acquisition unit.
If the WQAR is moved between multiple aircraft where both BI-PHASE and BI-
POLAR are used alternatively, the signal mode can be put into DISCRETE
mode where, during bootup, it monitors the BI-PHASE SELECT discrete. If this
discrete is active, the WQAR will set itself to BI-PHASE. If this discrete is not
active or not present in the aircraft, the WQAR will set itself to BI-POLAR.
After determining the signal, it will determine the speed of the signal using
the methods described above.
ACMS Reporting
In addition to the standard ARINC717 flight data, the WQAR can also record
ARINC429 data (ACMS reports) if the acquisition unit sends such reports.
When enabled, upon landing, the WQAR will power up the radios but wait a
