4. If the expected reception levels are not achieved, check for possible causes and solutions:
6.7 Broadcast Datalink Satellite Reception
The broadcast satellite network transmits signals that are received by an external Datalink receiver,
which sends the information on to the MFD through a serial connection. If the broadcast Datalink
antenna is not properly installed, or if there is excessive electromagnetic interference (such as a
nearby radio transmitter or inadequately grounded electronics), the system will not achieve consistent
reception.
➤ To assess system performance.
1. Bring the aircraft to an area that has as few obstacles to line-of-sight viewing to the southern
horizon as possible.
2. Select the Trip page on the EX500/EX600.
3. Press Display until Broadcast (down-pointing arrow) Status is selected.
4. The Signal Quality will be reported as Good, Marginal, Weak, or None. If the Broadcast Receiver
is working, the antenna and cabling are correct, and the aircraft is in view of at least one Broadcast
datalink satellite, the Signal Quality will be “Good” and the Receiver ID will be reported.
5. If the Signal Quality is not reported as Good, check for possible causes and solutions:
6. Service Level should display either Aviator or Aviator Lite, depending on your level of service.
■ If Activation displays, verify that a Broadcast subscription has been set up with the Broadcast
Service provider.
Possible Cause Possible Solution
The antenna field of view is
obstructed.
The antenna field of view is obstructed.
There is a local source of
electromagnetic interference:
■ Try shutting off any nearby sources (such as VHF radios, alternators,
magnetos, ground power cart).
■ Relocate the aircraft away from potential nearby sources.
■ Check electrical connections and grounds.
■ There is poor satellite coverage. Try again after fifteen minutes.
■ Check the antenna and cable for proper installation.
■ Check the connection between the antenna and its ground plane.
Possible Cause Possible Solution
The antenna field of view is
obstructed.
Try moving or rotating the aircraft.
Note: If rotation works, the antenna location on the aircraft
may not be optimal
There is a local source of
electromagnetic interference.
■ Try shutting off any nearby sources (such as VHF radios, alternators
and magnetos).
■ Relocate the aircraft away from potential nearby sources.
■ Check electrical connections to ensure there is no improper
grounding.
■ The antenna and cable are not properly installed.
■ The antenna may not be properly connected to the ground plane.
■ The cable may not be properly connected to the antenna or the
receiver.
