If it does not transmit, it will make the determination again at the next
destination. It will continue to do all of the above at every destination until
the aircraft arrives in a permitted cellular network where it will transmit all
accumulated data. If a transmission is interrupted for any reason, the WQAR
does not need to re-transmit from the beginning. It has the ability to resume
from the point of interruption. The radios will remain powered on while the
aircraft is on the ground whether transmissions occur or not. If the Download
on Demand (DOD) feature is enabled, the WQAR will accept any DOD
messages if they are sent. (See Section 1, Download on Demand, for details).
Contact Teledyne Controls Customer Services for more information.
If the cellular radios cannot transmit for any reason, data can still be
retrieved by ejecting the compact flash (CF) card using the procedure in
Section 4. After the card is ejected and files copied, the raw flight data files
need to be decrypted using Teledyne Controls WCCU. Compressed Flight data
(WGL files) are processed using Teledyne Controls' WDCU. See Section 5 for
specific details about viewing the log file on the card.
The WQAR can transmit up to two WGL files while receiving one file, all
simultaneously.

In general, there are two software components in the WQAR: The OPS
(operational software) and OPC files (configuration files). The OPS and OPC
files are ARINC 665 Loadable Software Parts (LSPs). Depending on the
context, the OPS and OPC LSP are referred to using different part numbers.
