Pilot of BE33 has difficulty determining restricted area airspace requirement under Den class B airspace with little info from charts or controllers at Buckley and Denver.

Narrative

Rewritten in plain English from NASA’s original all-caps telegraphic report — facts, figures, and terminology preserved.

Problem: May have inadvertently entered an area of temporary flight restriction. I was navigating from west to east across Denver metropolitan area. I was beneath class B airspace and was talking to Buckley tower with permission to pass through their class D airspace.

Immediately southeast of the Buckley class D is an uncharted area of temporary restricted airspace. The controller at Buckley did not mention it and I did not have it drawn in on my chart of Denver class B airspace. This NOTAM has been in effect for a long time, over a year, and should be charted for easier location.

The area is defined in the NOTAM cannot be located by any normal cockpit navigation equipment such as GPS or VOR/RNAV. It is defined as four corners of a box, with radials and distances from FQF VOR. It would be much easier to locate as a radius around a point and/or with GPS latitude/longitude coordinates.

As it is now, the only way to locate the restricted area is by drawing a picture on the chart. A reminder from the Buckley controller would have been very helpful, too.
