| Re: <nettime> Flying in Berlin's Sky, an Afternoon Investigation - September 22 |
Hi, Anyway...I am having a private conversation with Emmanuel on this, and he is happy to share his thoughts with you (see below). Here is his answer - hopefully you will get in contact directly with each other ;) - or at the workshop for the people that will join. Tatiana -------- ADS-B information is filtered by most websites. They don't show a high proportion of military and private planes. That's a fact which not really up for debate because it's very well documented. Regarding the proportion of planes that are blocked, Oxford researchers specialised in ADS-B and privacy did the study. They used actual data and you can view their methodology in their paper. See also table 7 here: https://www.cs.ox.ac.uk/files/9919/eurosnp.pdf You could also look at the Flightradar24 website itself, which explains that if you have a private aircraft you can make it non-visible on their website: https://www.flightradar24.com/commercial-services/aircraft-unblocking. As I mentioned, every website apart from ADSB-Exchange does this blocking. There's all kinds of arguments for this, such as privacy and security. The FAA is even planning to implement a rule to make it impossible for hobbyists to identify specific aircrafts. It's mentioned in the paper I linked above and this page: https://www.federalregister.gov/documents/2019/08/22/2019-18052/agency-information-collection-activities-requests-for-comments-clearance-of-new-approval-of You could also look up more information regarding the FAA ASID / Barr list. it's a list of aircrafts which have requested the FAA to forbid ADS-B websites (FR24, etc) from showing. This is in addition to all US military aircrafts: https://nbaa.org/aircraft-operations/security/asdi/ I've done a FOIA to get this list recently, and there's over 25,000 planes in it, that doesn't include the military ones. See my FOIA here: https://www.muckrock.com/foi/united-states-of-america-10/faa-barr-68856/ I'd be more than happy to discuss this further during the workshop. If anyone still have doubts, you could even compare "live" the data we get from our antenna vs what you see on the websites.
