Dynon SkyView SE - ADS-B OUT and Flight Plan Codes

Reported Pressure Altitude
At times it may be useful to know the altitude that is being reported to the transponder. Since
SkyView SE sends pressure altitude to the SV-XPNDR-261/262, setting BARO to 29.92 will
display the pressure altitude being transmitted to the transponder in the normal SkyView SE
altitude display on the PFD page.
ADS-B OUT Transmissions
If SkyView SE has a valid GPS signal and a SV-XPNDR-261/262 module is installed and working, it
automatically provides ADS-B output at the appropriate integrity level for the GPS signal being
used.
ADS-B OUT transmissions that meet the 2020 FAA ADS-B equipment mandate require that a
compliant GPS be provided to a capable ADS-B device (such as the SV-XPNDR-261). For this
purpose, a dedicated serial input is provided on the SV-XPNDR-261/262 module that allows an
appropriate GPS receiver serial output to be connected directly to the SV-XPNDR-261/262.
When an SV-XPNDR-261 is connected to a suitable GPS source – including Dynon’s SV-GPS-
2020) and is running the latest version of transponder software, the SV-XPNDR-261’s ADS-B
transmissions can attain the integrity level necessary to meet the FAA’s 2020 ADS-B equipment
mandate. Refer to the SkyView Classic / SE / HDX System Installation Guide for more details about
connectivity and information on updating the firmware on the SV-XPNDR-261 for this
compliance. Note that only the SV-XPNDR-261 is capable of meeting the 2020 ADS-B Out
mandate because of power transmission requirements that the FAA ADS-B rules imposes on
ADS-B transmitter devices.
If you are operating in a region where ADS-B broadcast is not permitted or may be
legally disabled, you can disable ADS-B OUT transmissions without disabling GPS-
based functions. (Refer to the SkyView Classic / SE / HDX System Installation Guide for
instructions.) Within the United States, ADS-B Out features must - per FAA rule - be
enabled if equipped.
If you are operating within the United States, there may be a service bulletin which
applies to your transponder, please see the Service Bulletins section of our website
for more information.
Flight Plan Codes
ICAO and FAA Flight Plans
If you do not have a certified GPS navigator on board, but do have a Dynon Mode-S
transponder, the appropriate ICAO Surveillance Equipment Code is "S".
