Mandate Summary (DO 260B)
• Europe - Forward Fit Mandate January 2015
– Retrofit Mandate now February 2017 or 2018
• 1 or 2 year slip
ANSP readiness
(ground systems
and integration) is
the core issue!
• Australia Upper Airspace (DO 260 )
– Voluntary, though separation services being provided today
– December 2013 Upper Air Space Mandate
• SA Aware GPS Sensors will be required
• For forward fit only
• Canada Hudson Bay & areas with limited SSR coverage (DO 260)
– November 2010 Exclusionary Airspace
• 5 NM separation services being offered
– No plans for a 260B mandate
• US DO 260B mandated by 2020
• No FF to RF segmentation – 100% equipped rule

GPS Requirements for DO 260B Mandate
• Europe
– The European Rule asks for (E)TSO-129A as a minimum
– SA=ON is acceptable
• Though SA=OFF (Aware) is preferred
• Canada
– SA=ON is acceptable
• Though SA=OFF (Aware) is preferred
• United States
Though not stated!
Likely will require GPS
– A GPS receiver that is SA Aware will be necessary
With WAAS. A reading
• FAA requirement is for a NACp of 8
of AC 90-ADS-B is
• 100% availability along enroute will determine GPS requirements
required?
• The quick summary of SA=Off/AWARE or SA=ON

–
Australian rule will require SA Aware for forward fit (2017)
FAA rule will require SA Aware at a minimum
Europe recommends SA aware (doesn’t require)
Canada recommends SA aware (doesn’t require)

ARINC 718A-3/4 Update - An indication of the changes
•
The development of DO-260B has required additional changes and
more inputs into the transponder
– GPS Antenna Position to support POA
• Requires about 32 states for ~ 2 meter accuracy
– Other installation related issues are being addressed in the A718-4 work
