OK, only tangentially FlightXML related I admit, but whoever feeds these APIs will know as it’s one of the sources you use.
I’m curious if the ASDI (Aircraft Situation Display to Industry) data fed by Seattle Center includes the optional secOfMinuteOfDegreeType data? Only degrees and minutes are required, seconds are optional. See fly.faa.gov/ASDI/asdidocs/Na … ements.xsd
If so, how long has Seattle Center included ‘seconds’ resolution? Since 2012?
Finally, is the frequency of TZ records realty only every 4 minutes, even close to KSEA?
Thanks,
David
