Instrument coverage and runway layout

Patuxent River combines three runway alignments with instrument approaches serving four of the six runway ends. The 13 approach charts include ILS, localiser and RNAV (GPS) procedures, giving both precision and non-precision coverage, while two ends have no published approach. Runways 06/24 and 14/32 provide substantially more available distance than the 5,021 ft runway 02/20, so the configuration offers both differing alignments and markedly different runway lengths.

Surrounding chart coverage

Nearby procedure coverage is much thinner: Cambridge-Dorchester Regional and Tappahannock/Essex County have the broadest nearby sets at four charts each, while Crisfield-Somerset County has only two. The Washington Sectional adds wider-area VFR context, while the Baltimore-Washington Terminal Area Chart supplies a more detailed VFR depiction around the airport.
