Although there could be many examples, I'm using the KLCQ airport in this case. This is how the airspace stands:


In the CHART Supplement, it is mentioned that it's a "Class D svc other times class E".


I called the Airport Manager and he confirmed saying "Yes, we're a Class D during the time tower is in service. Other than that, it's Class E".


1) Why does this airport not have a dashed blue circle like a normal Class D?

2) Since it's inside a Class E Transition airspace, shouldn't the airspace be Class G up to 700' AGL when tower is not in operation?

3) What is primarily required for an airport to actually be designated as a Class D airport - x amount of traffic, x amount services, x amount of weather reporting capabilities?

Why should this matter?

  1. Weather minimums
  2. Communications with ATC during arrival/departure
  3. Etc.

    $\begingroup$ Since you confirmed it is class D airspace it needs to have a blue dashed line. If it goes to class E airspace it may also require a magenta dashed line. Looks like you found an error. Report it. There is a way to report discrepancies on the sectional chart informational tab. $\endgroup$

    $\begingroup$ I suspect the chart update is lagging behind the airspace changes there. See this answer for some related information. $\endgroup$

  • $\begingroup$ Class D need a tower and alternate airport-approved weather reporting $\endgroup$

  • $\begingroup$ I just pulled this airport up in ForeFlight and the blue dashed line is there, inside the magenta Class E boundary. So the charts have caught up with the change in airspace classification. $\endgroup$
