First of all, thank you to each and every member of this community who takes times to reply to silly questions of people like me.
Most of the times when I come in for landing, I am not lined up perfectly with the runway (the LOC is little to the right/left). Then when I try to adjust the HDG via autopilot, the plane veers a bit to left or right (even for 1 degree adjustments). If I manually control the heading, it becomes impossible to line up, with heavy veering of the aircraft to either side.
How do I line up perfectly with the runway centerline? I see some cases where the LOC appears like a single line (such perfect alignment).
