An aircraft vectors to intercept the ILS at KCVG 0720 . the icon appeared to slide backwards during the total decent to intercept. Interesting. I could not identify It for reference.
Just saw another one doing the same thing! 0730
11:20 and 11:30 Z
Now COM 448 is doing the same thing. 1200 Z
I know that this probably a radar feed quirk!
BUT the 1st time I have seen a jet forward slip to lose alt and speed! LOL
