THY72C continues on to Dakar and then returns to Istanbul using the same flight ID so the data reads THY72C,THY595,LTBA,LTBA,GOOY. As we can only have one via point I have used the last stop before it returns as the via point so GQNO will not be included on this occasion.
I have changed all reference to GQNN to read GQNO in the routes database. I cannot remove GQNN from the database but have removed all the info apart from the ICAO code and have added all the pertinent data for GQNO. Unfortunately as the airports are hard coded into the Radarbox software I cannot remove GQNN from the Radarbox map or add GQNO to it although the route line will terminate at the correct location as per the lat/lon co-ordinates.
Many thanks
