Hi, I wanted to fly to OTHH yesterday with the A350. I loaded the Simbrief plan as usual, using the latest Navigraph cycle. Unfortunately, despite repeated attempts, the plane didn't detect the ILS for runway 6L during the approach, nor did it detect the LOC. I installed the new OTHH scenery. Then I noticed that the Navigraph data shows a landing course of 156 degrees, but the Navaids show 155, although the frequency is correct. Does anyone have any idea what might be causing this or have had similar experiences?
