ILS not really accurate.

Hello! I don’t know if it’s me but anywhere I fly my ILS is usually not accurate, and yes, my runway is center, I check it always. But it seems that the ILS is always 1 or even 2 degrees off for me. Is it me or not?

If you are talking about how you set the Heading when on the ILS to the runway heading number then that is why. Runways are rounded to the nearest 10 I believe. That is why you find a runway called 09L even though the runway is actually 94 degrees heading.

I Recommend either using APPR for the main part of the ILS approach or just doing a regular Visual approach and hand fly the aircraft straight in.


Not entirely sure what issue you’re having, but the following could be a couple of answers:

  • Crosswinds, meaning your aircraft’s “heading” will be a bit off from what the plane is actually flying (use the FPV as a guide as to whether you’re on target)

  • Rounding to whole degrees, when in fact a runway heading could be something like 094.35 but would still be Runway 09 and the ILS would say 94° - over time this would mean you end up off-centre


you likely have a crosswind which differs your planes heading
