In Tanzania it is mandatory to hold an IR rating when flying aircraft above 2300kg. If the weather is too bad at destination ie no hole then we just head back to kilimanjaro international and shoot the ILS. Believe our counterparts in Kenya do the same by going to jomo kenyatta. Unfortunately the 206 doesn't fall in this catergory so there is a chance that the pilot flying you will not have an IR. However most pilots now come out of with a CPL and IR....
Even if the pilot had held an IR rating, good on him on trying to find a hole
