Areas surrounding military runways that must be kept clear of objects that could damage an aircraft. This layer is a member of the "Military" feature dataset, which contains layers related to military installations and flight training areas in the state of Maryland.

Aerial corridors in which military aircraft are permitted to fly faster than 250 knots (about 285 mph) and under 10,000 ft. Routes are divided into visual rules (VR) and instrument rules (IR, at night and in poor weather conditions). This layer contains military training routes (MTR) with a floor elevation of up to and including 500 ft. This layer is a member of the "Military" feature dataset, which contains layers related to military installations and flight training areas in the state of Maryland.,Data source: Military Aviation and Installation Assurance Siting Clearinghouse website (https://www.acq.osd.mil/dodsc/about/maps.html),Last updated: between 8/15/2019 and 9/11/2019 (Cycle 1909),Recommended data update schedule: yearly,Contacts sources: websites for the military installation to which each MTR belongs. Recommended to check for updates when checking for new MTR data, approximately yearly.

The Aerial Firing/Weapons Separation Testing Area is within the Atlantic Test Range – Inner Range and over the Chesapeake Bay in which the DoD evaluates discharge characteristics from weapons and other equipment off aircraft. Military testing areas include firing and bombing ranges where the DoD tests weapons systems and equipment, which include releasing ordnance and other projectiles from aircraft, watercraft, as well as from land-based artillery. These areas can be particularly hazardous for development as some weapons systems and ordnance being tested can contain live ammunition and explosives.
