I’ve undergone some frustrations with the Kodiak here in New Zealand. There seems to be a certain sector of airspace that causes X-Plane 11 (now 11.10rc3) to invariably crash. I can fly from the north to Raglan and Hamilton and from there, south to New Plymouth, but trying to fly east always causes a software crash.
To get around this problem, I flew the Cessna Skyhawk from Raglan to Hamilton (…because there was one there to rent with GPS), from Hamilton to New Plymouth, and finally from New Plymouth to Gisborne. As you can see from my log below, I also flew the Cessna Caravan from Hamilton to Matamata, from Matamata to Tauranga and from Tauranga to Great Barrier Island.
I was also able to fly from New Plymouth to Ohakea Military Airport on the coast south of New Plymouth. I am currently enroute to Nelson, on the South Island. From there, I will try to work my way back north on the east side of the north island.
