The custom weather setting possiblities are highly flexible, almost every parameter for any weather conditions can be set. The visible results are stunning, simply unique.
I’m using these custom weather setups to perform ILS approaches in IFR weather conditions.
ILS landing procedures are classified by 5 categories of precision approaches.
CAT I, CAT II and CAT III A, B and C
Each category is defined according to the applicable decision altitude (DH) and the runway visual range (RVR). For non precision approaches ground visibility is given, e.g. in METAR reports.
Unfortunately none of both, RVR and / or visibility, can be choosen as preset in the custom weather setup. MSFS could be an ideal – semiprofessional – tool for PC IFR traing if one could easily setup different weather conditions which represent the 5 categories of (CAT X) precision approaches.
