According to all documentation, including the South African Civil Aviation Authority (CAA) the ILS frequency on RWY 07 at FALA (Lanseria Airport) is 110.70 (LAI) and not 110.90 as in X-plane. Also correct according to Navigraph as 110.70
Is there an option to correct this or is an update coming shortly which will correct this mistake? A wrong frequency may lead to an imminent disaster! :)
