Ok, luckily I have the airstrips in my Google Earth, which show up as red polys, so it is reasonably easy to pinpoint them in the TMFViewer, and then FSX.
I've assumed that if there was a problem, it would be in the 9444 landclass file, which is the tile covering Whangarei all the way north. I've selected a handful (a technical term:) of airstrips and checked for them in FSX, and they all show up.
Maybe this is just that they are not so visible, after a landclass change in the update? I think that Tim might have made a change to the way that pasture is displayed, and I suspect that a lot of airstrips are surrounded by pasture, so they might not stand out so much. Pretty much like in real life, you'd need to know where most of them are to find them.
Here's a sample shot, you can make out the airstrip, but it is in fact sitting in a very similar landclass poly.
