Most Challenger operators are now well aware of the 2020 mandates for ADS-B transponder upgrades for both the U.S. and Europe. However, we find that many are not aware of the ADS-B standards, options, and prerequisites required.
Here’s a quick explanation…
There are three ADS-B standards: DO-260, DO-260A, and DO-260B. Areas such as Australia, Hong Kong, Singapore, and the Hudson Bay in Canada have implemented ADS-B to the earlier DO-260 / 260A standards. The United States and Europe will mandate that all aircraft be equipped for ADS-B to the later DO-260B standard.
For Challenger 300 and Challenger 605 aircraft, all of which are Rockwell Collins Pro Line 21 equipped, the Pro Line 21 Advanced block upgrade must be performed as a prerequisite to the new ADS-B Service Bulletins that cover the DO-260B standard.
There are STCs available for both aircraft models that do not require the Pro Line 21 Advanced upgrade but do require WAAS GPS receivers as a prerequisite.
Both the SB and STC solutions for the Challenger 300 and Challenger 605 aircraft will meet the DO-260B standard.
The ADS-B SB for the Challenger 604 aircraft currently meets the DO-260A standard for areas such as Australia, Hong Kong and Singapore. However, it does not meet the DO-260B standard required for the U.S. and European mandates in 2020.
Like the Challenger 300 and Challenger 605 aircraft models, there are STCs available now that meet the DO-260B ADS-B standard.
We anticipate a factory SB solution for DO-260B will become available later this year. WAAS GPS receivers are required prerequisites.
We do not expect an ADS-B service bulletin becoming available for the Challenger 601-3A and -3R aircraft models. The good news is there are a number of STCs available now that meet the DO-260B standard. These STCs cover aircraft equipped with the Honeywell Primus II and Collins TDR-94D transponders.
As with the others, WAAS GPS receivers are a prerequisite and accomplished per a Duncan Aviation STC upgrading the NZ-2000 FMSs to 6.1 level software and WAAS / LPV.
