Thx for the reply, I use all kinds of planes, Airbus and Boeing mostly, I just remember how I watched these youtube videos on how to land with ILS, most of them dont require to push the Approach mode. Should you press the NAV along with the APP ?Arvid : Yes, sorry about that, I usually put in the airport frequency in the NAV1 and I press the NAV before the ATC gives me clearence to land.I'ts just that before I got my PC fixed it used to work on every airplane and I didnt had any problems :( they were all decending after just pressing the NAV button, I was just decending the aircraft only the lowest ATC would command me.
