Hi there! Please make sure your source is GPS, not NAV1/2.

this may be because you accidentally touched the appr button, to solve that you need to go to NAV and change the ADF 1 source to GPS

Now I have to appoligize to my F/O for blaming him lol I forgot I swiched it when I was arriving into SBGR thanks for y’all help


no problem, that has happened to me too hehe
