what info provided by Mode S xpdr to ATC?

Postby howardnmn » Thu Aug 18, 2016 7:06 pm

on a recent 135nm trip to Truckee airport (5900') from SF Bay Area several controllers asked what is my 'type?'

my 2013 SLSA is equipped with Dynon Skyview including ADS-B and mode S

i thought one thing Mode S communicated 'automatically' with ads-b was ICAO Type; also cruise speed, airplane ownership etc

what info does ATC get besides altitude & location & direction?

is there a FAA procedure to determine if one's a/c is 2020 compliant?

Mode S sends your Mode C altitude plus a unique code assigned to your aircraft. One could theoretically look up that code and find your type and registration number, but that information is not instantly available to ATC. 2020 compliance adds Extended Squitter to your mode S data stream. Those bits hand off your position information as derived from a TSO compliant WAAS GPS. To test for 2020 compliance, get yourself into radar contact with a NextRad ATC facility. After landing, there's a website you go to. Enter your unique Mode S code and print out your compliance report. (This serves as your required 24 month check).
