Runway surface defaults to 7' AGL

[Guest Catandra]

Hey Gents,I have an airstrip on a very low island (essentially at sea level). Problem is, when a plane lands there, it shows in the sim as being seven feet above the runway. It just looks like it's floating there....When I consulted the map view, it onfirmed I was at 7 agl.A closer look at AFCAD shows the airstrip at 0 feet, so why would the plane be floating there?Any ideas?

Is this an addon scenery? There is probably a default flatten in one of the HP files. You could possibly correct it with JABBgl.George
