This is inspired by the question regarding aerobatics over a surface class D area.

KINS (Creech AFB) sits right outside the south boundary of the Nellis Range Complex (R4806W to be precise). Considering this, and considering that it has surface Class D around it whenever the tower's open as per the A/FD...does that class D airspace abruptly end where R4806W begins just north of the airbase, or does it continue all the way around, leaving a portion of airspace that's both a Class D (sfc) area and SUA (i.e. restricted airspace)?


According to the sectional chart, Class D airspace does not extend into the restricted area.

The restricted airspace starts at the surface to an unlimited altitude. According the JO 7400_11A.pdf, Class D does not enter the restricted area.

Class E airspace is the same.

  • $\begingroup$ The sectional chart does display it that way -- but I'm not sure if that reflects the actual airspace boundaries, is a charting limitation, or if something else is going on (note that the vignette doesn't extend along SUA boundary) $\endgroup$ Feb 10 '17 at 4:28
  • $\begingroup$ Vignette? Are you talking about Class E airspace starting at 700' AGL. If so, it stops where the restricted area begins leading credence to Class D also stopping where the restricted area begins. $\endgroup$

  • $\begingroup$ Ah -- I got the vignette and the dashed line mixed up -- but you'd think they'd draw a dashed line (and/or vignette) parallel to the SUA boundary if the Class D and E airspaces ended at the SUA boundary, no? $\endgroup$ Feb 10 '17 at 4:38
  • $\begingroup$ Page 377 of the linked to document contains the information you are looking for. It is regulatory in nature as it is referenced in §71.61. $\endgroup$

  • $\begingroup$ That's exactly what I'm after, thanks! $\endgroup$ Feb 10 '17 at 4:51
