General notes are numbered notations which apply to the entire drawing in general and provide requirements applicable to the item or portion of the item depicted. Local notes. Local notes are notes which are located at the specific area or point of application. Requirements specified by local notes apply only to the areas or points indicated. Flagnotes. Flagnotes are notes which are located with the general notes but apply only at specific areas or points on the drawing. A flag note shall be identified with a flag note symbol delta “”. The flag note delta including the general note number shall be shown at each point of application on the field of the drawing. The general note shall state “surface(s) indicated”, “area(s) indicated”, or “adjacent surfaces optional” as appropriate to tie the delta on the field of the drawing to the general note.
