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?
- Weather minimums
- Communications with ATC during arrival/departure
