blocked tail numbers


Do aircraft have the ability to block there tail number ID ramdomly???
Have noticed recently in running aircraft numbers into our terminal that they aircraft does not appear on the arriving flight but may have a history from previous flights several days(weeks) earlier.


Read the Questions/Answers available at the top right hand side of every page.

Also, it’s always great to provide examples rather than saying something generic like “running aircraft numbers into our terminal.”


With a blocked tail number, you won’t be able to see the aircraft page at all.
The aircraft likely arrived VFR, using a callsign, or was local enough that we didn’t recieve any information about the flight.
