Just a quick question, I wondering wether this is a bug or if I’m doing something wrong.
I flew into Perth from Auckland, IFR. My RVR was 75m, so I took advantage of Perth’s ILS 27 Z approach which is Cat III B in real life.
The rule for a Cat III B approach with less than 75m RVR is dual AP for failover. However, I cannot seem to activate DUAL AP. My PFA shows CAT 3 Single and the AP2 button just disengages AP1.
Is this a missing feature or am I doing something wrong?
