I'm sure this is covered elsewhere, but am battling to find info, so please humore me. For some od reason my Heading hold does not seem to work. I turn my hdg hold on if for eg I'm flying on a hdg of 090 and I want to fly 120 degrees, I move the wheel so that I get the desired heading, but the aircraft will only turn to within 10 or so degrees. What am I doing wrong? I use hdg quite a bit when flying approach vectors from ATC.

I'm probably doing something very basic wrong, but I can't figure wrong. This works different from what I know. I'm assuming the 757 is similar, So might as well find out now.

Ahhh, got it, thanks
