Sorry I lumped the Islanders with the Trilanders - The Islanders don't have an HSI or a slaved DI or a panel GPS. Does not get any harder. Its not cargo its pax and your landing at night into a coastal windy field with only an NDB IAP (Alderney) no slaved DI, no HSI, no RMI, no GPS, no autopilot and no co-pilot. What is tougher?
