Aviation flight rules. The regulations, directives, or procedures that govern the conduct and operation of manned and remotely piloted aircraft. These rules are normally established for IMC and VMC.
Concept of operations. A concise graphic, verbal, or written statement that gives an overall picture of a commander's scheme with regard to an operation or series of operations and includes the scheme of maneuver and fire support plan. It is frequently referred to as the commander's concept. It is described in sufficient detail for the staff and subordinate commanders to understand what they are to do and how to fight the plan in the absence of further instructions.
Controlled airspace. Airspace of defined dimensions within which air traffic control service is provided to controlled flights.
Control point. A position marked by an electronic device, a conspicuous terrain feature, or other identifiable object which is given a name or number and used as an aid to navigation or control of aircraft. (Also known as air control point.)
Coordinating instructions. Orders or information that applies to two or more units.
Effective wind message. Information on wind speed and direction used for predicting NBC contamination.
Enemy aircraft low level avenues of approach. An air route which allows threat forces to fly sufficiently close to ground level so that detection or engagement is avoided or minimized. It is usually associated with routes that allow flight below the altitude of the surrounding terrain, for example, valleys, river basins.
Fire support coordination measures. Procedures or directives used to manage fire support assets. Some examples are coordinated fire line, free fire zone, and fire support coordination line. All control measures can be depicted graphically.
Fire support priorities. The ranking by the commander to establish an order of importance for the collective employment of mortars, field artillery, close air support, and naval gunfire.
Fire support unit locations. The position or site occupied by fire support elements which are capable of delivering fires. Normally, battery-sized elements are reported, but they may include platoon/sections if they are separated from their battery.
Fire support unit status. The condition or current state of affairs of a unit which provides supporting indirect fires. Normally, for field artillery a fire unit is considered a battery-sized element, but the unit may include platoons if firing batteries are split.
Flight coordination center location. The position or site occupied by the FCC.
Flight operations center location. The position or site occupied by the FOC.
Flight plan. Specified information provided to air traffic services units relative to an intended flight or a portion of a flight of an aircraft.
Forward arming and refueling point. A temporary facility organized and deployed by an aviation unit located closer to the area of operations than the aviation unit's normal service area. FARPs are established to provide classes III and V to aviation units conducting combat operations. Report FARPs for A²C² purposes when they are not collocated with an airfield/assembly area/ laager site.
Forward line of own troops. A line which indicates the most forward positions of friendly forces in any military operation at a specific time.
Friendly aircraft location. A report on the location of friendly aircraft expressed in altitude and relative ground position. Reports are used to accomplish regulation and resolve conflicts. Friendly aircraft location is also used to improve aircraft identification.
