Feb 2, 2020 at 15:49 comment added Dean F. @pcfreakxx - Thank you for your expert insight. Since this is a military aircraft, presumably, taking off from a military facility, would the same apply? Or, are the military controllers monitoring primary returns as closely during peace time as they would during a major conflict? I would think the area involved would play a role in this as well. Say for instance, what is the protocol in the DC FRZ or any other SFRA or ADIZ? Thanks again. Your input is appreciated.
Feb 2, 2020 at 14:38 comment added pcfreakxx @Dean F. I am an ATCO myself and if aircraft loose there transponder they will disappear completely from the SDD after 3 coasted plots (~15,3 secs). Of course primary radar would still detect the aircraft, however the question was not if the acft would be invisible to radar but to ATC!
Feb 2, 2020 at 14:35 comment added Dean F. @pcfreakxx - A pilot can not make a non-stealth-technology plane in normal flight invisible by switching off its transponder. It would just become unidentifiable. By flying too low, too slow, and/or too close to another aircraft, you can hide the aircraft’s radar return.
