Was planning a flight from Kathmandu (VNKT) to Skarku in Pakistan (OPSD). Simbrief recognizes the airport, but it does not show on the Navigraph Desktop map (7.6.1). Only the OPSD airport identifier icon, but no airport data - layout, stars,etc.
OPSD is connected to Pakistan’s capital, Islamabad in mainland Pakistan through regular Pakistan International Airlines flights, so I would assume it to be included.
