(See DISTANCE MEASURING EQUIPMENT.)DOD FLIP. Department of Defense Flight Informa-tion Publications used for flight planning, en route, and terminal operations. FLIP is produced by the National Imagery and Mapping Agency (NIMA) for world-wide use. United States Government Flight Information Publications (en route charts and instrument approach procedure charts) are incorpo-rated in DOD FLIP for use in the National Airspace System (NAS). DOMESTIC AIRSPACE. Airspace which overlies the continental land mass of the United States plus Hawaii and U.S. possessions. Domestic airspace extends to 12 miles offshore. DOWNBURST. A strong downdraft which induces an outburst of damaging winds on or near the ground. Damaging winds, either straight or curved, are highly divergent. The sizes of downbursts vary from 1/2 mile or less to more than 10 miles. An intense downburst often causes widespread damage. Damag-ing winds, lasting 5 to 30 minutes, could reach speeds as high as 120 knots. DOWNWIND LEG. (See TRAFFIC PATTERN.)DP. (See INSTRUMENT DEPARTURE PROCEDURE.)DRAG CHUTE. A parachute device installed on certain aircraft which is deployed on landing roll to assist in deceleration of the aircraft. DSP. (See DEPARTURE SEQUENCING PROGRAM.)DT. (See DELAY TIME.)DTAS. (See DIGITAL TERMINAL AUTOMATION SYSTEM.)DUE REGARD. A phase of flight wherein an aircraft commander of a State-operated aircraft assumes responsibility to separate his/her aircraft from all other aircraft. (See also FAAO JO 7110.65, Para 1.2.1, WORD MEANINGS.)DUTY RUNWAY. (See RUNWAY IN USE/ACTIVE RUNWAY/DUTY RUNWAY.)DVA. (See DIVERSE VECTOR AREA.)DVFR. (See DEFENSE VISUAL FLIGHT RULES.)DVFR FLIGHT PLAN. A flight plan filed for a VFR aircraft which intends to operate in airspace within which the ready identification, location, and control of aircraft are required in the interest of national security. DVRSN. (See DIVERSION.)DYNAMIC. Continuous review, evaluation, and change to meet demands. DYNAMIC RESTRICTIONS. Those restrictions imposed by the local facility on an “as needed” basis to manage unpredictable fluctuations in traffic demands. PCG D.4 E EAS. (See EN ROUTE AUTOMATION SYSTEM.)EDCT. (See EXPECT DEPARTURE CLEARANCE TIME.)EFC. (See EXPECT FURTHER CLEARANCE (TIME).)ELT. (See EMERGENCY LOCATOR TRANSMITTER.)EMERGENCY. A distress or an urgency condition. EMERGENCY LOCATOR TRANSMITTER. A radio transmitter attached to the aircraft structure which operates from its own power source on 121.5 MHz and 243.0 MHz. It aids in locating downed aircraft by radiating a downward sweeping audio tone, 2-4 times per second. It is designed to function without human action after an accident. (Refer to 14 CFR Part 91.) (Refer to AIM.)E-MSAW. (See EN ROUTE MINIMUM SAFE ALTITUDE WARNING.)EN ROUTE AIR TRAFFIC CONTROL SER-VICES. Air traffic control service provided aircraft on IFR flight plans, generally by centers, when these aircraft are operating between departure and destination terminal areas. When equipment, capa-bilities, and controller workload permit, certain advisory/assistance services may be provided to VFR aircraft. (See AIR ROUTE TRAFFIC CONTROL CENTER.)(Refer to AIM.)EN ROUTE AUTOMATION SYSTEM (EAS). The complex integrated environment consisting of situation display systems, surveillance systems and flight data processing, remote devices, decision support tools, and the related communications equipment that form the heart of the automated IFR air traffic control system. It interfaces with automated terminal systems and is used in the control of en route IFR aircraft. (Refer to AIM.)EN ROUTE CHARTS. (See AERONAUTICAL CHART.)EN ROUTE DESCENT. Descent from the en route cruising altitude which takes place along the route of flight. EN ROUTE FLIGHT ADVISORY SERVICE. A service specifically designed to provide, upon pilot request, timely weather information pertinent to his/her type of flight, intended route of flight, and altitude. The FSSs providing this service are listed in the Airport/Facility Directory. (See FLIGHT WATCH.)(Refer to AIM.)EN ROUTE HIGH ALTITUDE CHARTS. (See AERONAUTICAL CHART.)EN ROUTE LOW ALTITUDE CHARTS. (See AERONAUTICAL CHART.)EN ROUTE MINIMUM SAFE ALTITUDE WARN-ING. A function of the EAS that aids the controller by providing an alert when a tracked aircraft is below or predicted by the computer to go below a predetermined minimum IFR altitude (MIA). EN ROUTE SPACING PROGRAM (ESP). A program designed to assist the exit sector in achieving the required in-trail spacing. EN ROUTE TRANSITION. a.Conventional STARs/SIDs. The portion of a SID/STAR that connects to one or more en route airway/jet route. b.RNAV STARs/SIDs. The portion of a STAR preceding the common route or point, or for a SID the portion following, that is coded for a specific en route fix, airway or jet route. ESP. (See EN ROUTE SPACING PROGRAM.)ESTABLISHED.To be stable or fixed on a route, route segment, altitude, heading, etc. ESTIMATED ELAPSED TIME [ICAO]. The estimated time required to proceed from one significant point to another. (See ICAO Term TOTAL ESTIMATED ELAPSED TIME.)PCG E.1 ESTIMATED OFF-BLOCK TIME [ICAO]. The estimated time at which the aircraft will commence movement associated with departure. ESTIMATED POSITION ERROR (EPE). (See Required Navigation Performance)ESTIMATED TIME OF ARRIVAL. The time the flight is estimated to arrive at the gate (scheduled operators) or the actual runway on times for nonscheduled operators. |
