Sometimes a Class D airspace can be designated to change to E2 when the tower closes, in which case there will be no specific depiction of the E2 on the chart other than the depiction of the Class D airspace.

Unfortunately the phrase "Designated as a Surface Area for an Airport" is somewhat confusing and would seem at first glance to also include E4 airspace, until we read further down the list.

The intention may be just to emphasize that the E4 airspaces extend all the way down to the surface, but considering the way that both the "Airspace Designations and Reporting Points" document and the AIM use the phrase "surface area" in association with E2 airspace but not E4 airspace, the phrase "become part of the surface area" seems to carry some implication that the E4 airspaces may actually become E2 airspace, or may function exactly like E2 airspace, whenever the adjoined E2, D, or C airspace is in effect. rev 2020.12.4.38131, The best answers are voted up and rise to the top, Aviation Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us.
