"After doing flight data monitoring for some years now, I can tell you that one of the most common cause for unstabilized approach is selecting LOC before APP - about 60% of tle flights the crew forgot to select APP and remained above GS"
V celom odkazovanom strome sa rieši, aký je správny postup, či VOR/LOC a potom APP, alebo priamo APP. Vyzerá to tak, že FCOM hovorí priamo APP, ale je možné, že SOP tej-ktorej spoločnosti to bude definovať úplne inak.
