Evening guys, when i start from cold n dark etc i get everything set up sweet, i enter the runway and i cant activate the nav button to follow my route, and instead it shows my a/c heading 90 degrees anti clockwise to where i should be heading ie if i put 258 to leave egkk 26l, my heading points to 160 deg or something like that, and i cant get it to activate whatsoever, it worked ok before and yet im not doing anything different to what i did before,Thanks paul westcott

After lining up on the runway, push the heading knob so that the heading indicated matchs the runway heading. Double check that you do not have a dashed line around the outer part of the ND as that indicates the direction the plane should turn to reach the selected heading.

Hi paul, thanks for the reply, ill try it again, thanks
