When is this Class D airspace not Class D airspace? The Terminal Area Chart (TAC) shows the Class D airspace for Los Angeles International Airport (KLAX) view the full TAC. I have highlighted in green the north and south portions of the Class D airspace. The surface area directly over KLAX airport is Class B airspace.  The note - "See NOTAMs/Supplement for Class D eff hrs" is highlighted in green on the left side with arrows pointing to the two Class D areas (2700 and 2500).

This note suggests that at certain times, these two KLAX Class D areas may not be effective.

The excerpt just below the TAC is from FAA Order 7400.11 - Airspace Designations and Reporting Points and describes the official dimensions of the KLAX Class D airspace and also indicates it (Class D) may not be continuously effective.

The next to last section below is an excerpt from the Chart Supplement Southwest U.S.  (just the pertinent part). The Airspace description shows it is Class B airspace and Class D airspace with "...other times CLASS G"

The final section below is a 2012 FAA Notice (NOTC 3900) announcing the activation of LAX Class D airspace, validating that LAX has Class D airspace north and south of its runways.

My question is: When are these two (2700 msl and 2500 msl) Class D airspace sections (bordered in green) other than Class D?





FAA NOTICE NOTC 3900 - LAX CLASS D Airspace Activation
Great question. The short answer to your question is &quot;Full Time.&quot; Ultimately that Class D airspace will be incorporated into the LAX Class B, but there is a lot of red tape involved so step one was to add the Class D extensions, then it will be incorpoated into LAX Class B at a later date. Its a big deal, Title 14 CFR Part 71 had to be amended, here is the Federal Register page that explains the rule change. By the way, you're not alone in being confused about the effective hours, apparently that language was erroneously included in the charts and had to be removed.
