I would have thought this was a safety issue. Case in point - Hearst Castle Airfield. This is located beneath William Randolph Hearst's Castle in California, located at 35°39'35.54"N 121°11'35.64"W.
It is very obviously a well maintained runway, although private; yet is simply does not exist if you were to believe the VFR sectionals. It did appear in older sectionals, as discussed on the forgotten airfield site (http://www.airfields-freeman.com/CA/Airfields_CA_SanLuisObispo.htm#hearst2), but now not.
If you look at skyvector (https://skyvector.com/?ll=35.658914169287556,-121.18517303105294&chart=301&zoom=1&fpl=3539N12110W), the runway should be right smack under the crosshairs inthe center, where the map is marked "ranch". But it's not there. How can this be allowed by the FAA? Even secret CIA runways are listed on sectionals.
I assume that the Hearst Castle administrators requested removal of the field from the map. Isn't this a safety issue - in the event of an in-flight emergency, this would be a perfectly good field to land on, but being unmarked, there is no way to know it is there. How can this be?
