Introduction
The Teledyne Controls new Wireless GroundLink® Quick Access Recorder,
also known as the WQAR, is the latest addition to the QAR family of products
(Figure 1). This compatible replacement for any QAR provides convenient
access to airborne data by transmitting it over a high-speed cellular
connection. It can receive flight data from any acquisition unit that is ARINC
717 compliant. The front panel display gives status while the buttons allow
the operator to perform testing as well as view the configuration of the unit.

WQAR Operation Overview
The primary purpose of the WQAR is to record and store flight data provided
to it by a data acquisition unit such as a DFDAU or FDIMU. Then, while the
aircraft is on the ground, it wirelessly transmits that data to a base station
using high-speed 3G/4G-like cellular technology (where available). If unable
to transmit, a backup encrypted copy of your data is stored on the removable
Compact Flash (CF) card.

Features
The Wireless GroundLink Quick Access Recorder has many features which
enable it to fit into almost any aircraft infrastructure.
Aircraft Signaling
The WQAR can support two different aircraft signaling types: Bi-Polar and
Harvard Bi-Phase. Either one of these signal types can be entered in the
configuration. However, if the WQAR is moved between multiple aircraft
where both BI-PHASE and BI-POLAR are used alternatively, the unit can be
put into signal 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 below:
❖ The standard hard-coded 64, 128, 256, 384,512, 1024, and
2048 WPS rates can be configured.
❖AUTO speed mode where it dynamically determines the
WPS rate of the signal as it is coming in.
❖Speed DISCRETE mode where, during WQAR bootup, it
determines the speed by monitoring speed discretes
activated by the acquisition unit. These discretes are
generally known as the X2, X4, X8, X16, and X32 discretes.
The aircraft wiring of these discretes varies by aircraft type.
The acquisition unit may activate any one of these to
indicate the speed of the ARINC717 data stream.

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
fixed amount of time before sending any data to allow for these reports to
come in. This delay is referred to as the Recording Completion Delay (RCD).
The typical setting is five minutes. Once the RCD has elapsed, the WQAR will
transmit both the ARINC717 and ARINC429 data in a single (WGL) file. Each
flight is compartmentalized into distinct compressed files.
RF Interlocks
Aircraft regulations prohibit the WQAR radios from transmitting while the
aircraft is in the air. To comply with this regulation, Teledyne Controls has
incorporated hardware, referred to as High Reliable RF Interlocks, which
provides strict controls to allow power to be applied to the radios only while
the aircraft is on the ground.
Removable SIM Module (RSM)
This WQAR is equipped with a Removable SIM Module (RSM) which located
behind the front Access Door. After WQAR power is removed, the RSM can
be removed by the operator using the procedure in section 4, View/Replace
Removable SIM Module (RSM) or Individual SIM Card. When replacing or
installing the individual SIM cards (mini-SIM cards) into the RSM, the WQAR
may require a new OPC file for proper operation.

UG2243800-4XX
May 28, 2019
Mobile Networks
The WQAR transmits data utilizing the 3G/4G networks all over the world, by
dynamically determining the cellular frequencies wherever the aircraft is
located. The operator can selectively limit where the WQAR transmits by
utilizing the roaming zones set by the mobile provider or by use of Network
Identification numbers (NetIDs). All transmissions are subject to charges by
the SIM mobile provider(s).
Transmission Restriction
The WQAR is restricted to a maximum of 3 radios simultaneously transmitting
on band 30. To facilitate this restriction, the user must not utilize a SIM card
combination or transmission rules that allows access to more than 3 radios on
band 30 at a time.
Contact Teledyne Controls Customer Services for more information.
Radio Frequency Radiation Exposure Information
The WQAR complies with the FCC RF exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated
with a minimum distance of 20cm between the radiator (antenna) and your
body.

Section 2 –System Overview
Boot up and Pre-Flight Operations
Upon cold start, the WQAR FAIL light will blink slowly while it initializes the
hardware. The FAIL light will blink quickly as the OPS software boots,
determines the signal and speed of the incoming flight data, and adapts itself
to the aircraft. During this time, the output FAIL discrete will not be set. After
boot up is complete, the FAIL light will extinguish and the LCD display will
momentarily show STARTUP BIT COMPLETE followed by the normal SYSTEM
STATE display as shown in Section 3 which indicates the WQAR is ready for
operation. On LRUs without MOD DOT 3 status, the LCD display may be
dimmed during the boot up process which takes approximately two minutes.
In-FlightOperations
When the aircraft is ready, the WQAR will begin recording all incoming ARINC
717 and report data from the acquisition unit. During flight, the data will be
periodically compressed to ready it for transmission. An encrypted copy is
also saved onto an accessible removable CF card (P/N 2234641-008).
Post Flight Operations
After landing, the RF Interlocks will disengage and the radio(s) will power on
and make contact with the Wireless Ground Communication Manager
(WGCM). However, if the optional Recording Completion Delay (RCD) is
enabled, flight data will not transmit until the RCD has expired (See Section 1,
ACMS Reporting, for RCD details). During this delay, the WQAR will continue
to receive final airborne data and ACMS reports (if present). If the WQAR
determines that it has recorded the minimum amount of data, it will
compress this remaining data and close the file. Finally, it will send the flight
data to the WGCM if it is permitted to transmit at the current destination
(e.g. not roaming, etc).

Use and disclosure shall be in accordance with the proprietary information notice and DCS on page i.
UG2243800-4XX
May 28, 2019
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.
Part Number Discussion
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.
