I am working on the turnpoint file for a contest in the US that will be run to IGC rules instead of US/SSA rules. I could use some help with this request.

"The Landing Zone must show up in the AirSpace file, so people don't have to guess where it is, and the limit of it is officially defined. Very easy to include in a sua file." "The airspace within 1 km of the Gliderport and below 1500' MSL is designated as a Landing Zone. Pilots may enter the Landing Zone only from above and no continuous circling is allowed after entry. Landing Zone violations will result in penalties."

Main question: what class/type of airspace to code it as? [A,B,C,D, Danger, Prohibited, etc.]

I know how to edit "open air" airspace files to do this, Is it easy to translate this to a .sua file? Have you seen this done at other international sites?

Do you know of an example of this i could download? Since it is over the gliderport which is both a turnpoint and landing spot wouldn't I want the airspace to be depicted at translucent/transparent/clear so that the runway below is visible on flight displays?

thanks
Chris
