The magnetic heading of Runway 5 is zero five zero.


The magnetic azimuth of Runway 5 could be significantly different than 050.
A runway with magnetic azimuth of 045 through 054 would normally be
designated Runway 5. But magnetic azimuth changes over time, and as I
recall the directives allow for a difference of six degrees before
redesignation and repainting are required. But that's not adhered to very
closely. The ATW airport diagram shows the azimuth of RWY 29 to be 297.9
degrees. Runway 7L at MKE had an azimuth of 053 degrees before it was
rebuilt some ten years ago or so, no doubt to prevent confusion with Runway
7R.
