12/ 3 /25 N 8900.754 Appendix A Appendix A. Sample OpSpec A002, Definitions and Abbreviations: 14 CFR Part 129 Unless otherwise defined in these operations specifications, all words, phrases, definitions, and abbreviations have identical meanings to those used in Title 14 of the Code of Federal Regulations (14 CFR) and in Title 49 of the United States Code (49 U.S.C.) Subtitle VII, as amended. Additionally, the definitions listed below are applicable to operations conducted in accordance with these operations specifications.

Term or Terms Definition Air Ambulance (1) Air transportation of a person with a health condition that requires Operations medical personnel as determined by a health care provider; or (2) Holding out to the public as willing to provide air transportation to a person with a health condition that requires medical personnel as determined by a health care provider including, but not limited to, advertisement, solicitation, association with a hospital or medical care provider.

Agent For Service A person designated in writing by the foreign air carrier upon whom service of all notices, processes, decisions, and requirements of the Department of Transportation (DOT), FAA, and National Transportation Safety Board (NTSB) shall be made for and on behalf of the foreign air carrier.

Airways Navigation Airways navigation facilities are those International Civil Aviation Facilities Authority (ICAO) standard navigation aids (very high frequency omnidirectional range (VOR), VOR/distance measuring equipment (DME), and/or Non-Directional Beacon (NDB)) which are used to establish the en route airway structure within the sovereign airspace of ICAO Member States. These facilities are also used to establish the degree of navigation accuracy required for air traffic control (ATC) and Class I navigation within that airspace.

Alternate Airport An airport at which an aircraft may land if a landing at the intended airport becomes inadvisable.

Auto Flight Guidance Aircraft systems, such as an autopilot, autothrottles, displays, and controls, System (AFGS) that are interconnected in such a manner to allow the crew to automatically control the aircraft’s lateral and vertical flightpath and speed. A flight management system is sometimes associated with an AFGS.

Automatic Dependent A function for use by Air Traffic Services (ATS) in which the ADS Surveillance (ADS) equipment in the aircraft automatically transmits data derived from onboard navigation systems via a datalink. As a minimum, the data include aircraft identification and three-dimensional position. ADS is sometimes referred to as ADS-A or ADS-Contract (e.g., a communications contract between the aircraft communications/surveillance system and an air traffic facility or service provider only).

A-1 12/ 3 /25 N 8900.754 Appendix A Term or Terms Definition Automatic Dependent ADS-B is a function on an aircraft or surface vehicle operating within the Surveillance-Broadcast surface movement area that periodically broadcasts via datalink its state (ADS-B) vector (horizontal and vertical position, horizontal and vertical velocity) and other information. ADS-B is Automatic in that it requires no external stim ulus to elicit a transmission. ADS-B is Dependent because it relies on onboard navigation sources. ADS-B Surveillance information is provided, via data link, to any users (either aircraft or ground-based) within range of the Broadcast signal.

Available Landing ALD is that portion of a runway available for landing and rollout for aircraft Distance (ALD) cleared for land-and-hold-short operations (LAHSO). This distance is measured from the landing threshold to the hold-short point.

Category I Instrument A Category I instrument approach is any authorized precision or Approach nonprecision instrument approach which is conducted with a minimum height for instrument flight rules (IFR) flight not less than 200 feet (60 meters) above the touchdown zone and a minimum visibility/Runway Visibility Value (RVV) not less than 1/2 statute mile or Runway Visual Range (RVR) 1800 (for helicopters, 1/4 statute mile or RVR 1600).

Class I Navigation Class I navigation is any en route flight operation or portion of an operation that is conducted entirely within the designated Operational Service Volumes (or ICAO equivalents) of ICAO standard airway navigation facilities (VOR, VOR/DME, NDB). Class I navigation also includes en route flight operations over routes designated with a Minimum En route Altitude (MEA) Gap (MEA is established with a gap in navigation signal coverage) or ICAO equivalent. En route flight operations conducted within these areas are defined as “Class I navigation” operations irrespective of the navigation means used. Class I navigation includes operations within these areas using pilotage or any other means of navigation which does not rely on the use of VOR, VOR/DME, or NDB.

Cockpit Display of A CDTI is a generic display that provides a flightcrew with surveillance Traffic Information information about other aircraft including their position. Traffic information (CDTI) for a CDTI may be obtained from one or multiple sources (including ADS-B, Traffic Alert and Collision Avoidance System (TCAS), and Traffic Information Services (TIS)) to provide improved awareness of proximate aircraft and as an aid to visual acquisition as part of the normal see and avoid operations both in the air and on the ground.

Controller-Pilot Data A means of communication between controller and pilot, using data link for Link Communications ATC communications.

(CPDLC) A-2 12/ 3 /25 N 8900.754 Appendix A Term or Terms Definition Decision Altitude DA(H) is a specified minimum altitude in an instrument approach procedure (Height) (DA(H)) by which a missed approach must be initiated if the required visual reference to continue the approach has not been established. The ‘altitude’ value is typically measured by a barometric altimeter; the ‘height’ value (H) is typically a radio altitude equivalent height above the touchdown zone (HAT) used only for advisory reference and does not necessarily reflect actual height above underlying terrain. [This definition is consistent with both current U.S. operator usage and ICAO international agreements.]

Dry Lease Any agreement in which a lessor such as an air carrier, bank, or leasing company leases an aircraft without any crewmembers to a foreign air carrier (the lessee) and in which the lessee maintains operational control.

Dual-Certificated- For purpose of noise compliance rules, dual-certificated airplanes are those Noise Compliance that are certificated to operate in either a Stage 2 or Stage 3 configuration.

The only airplanes dual certificated by the FAA were certain Boeing 747s -300 series or earlier. For noise compliance purposes, these airplanes are considered Stage 2 unless the operator gets a Supplemental Type Certificate (STC) to make the airplane Stage 3 only, or unless the operator voluntarily limits the operation to Stage 3 only.

Fault Detection and FDE technology allows onboard GPS equipment to automatically detect a Exclusion (FDE) satellite failure that effects navigation and to exclude that satellite from the navigation solution.

Flight Management An integrated system used by flightcrews for flight planning, navigation, Systems (FMS) performance management, aircraft guidance, and flight progress monitoring.

Foreign Air Carrier For the purpose of these operations specifications, the term “foreign air carrier” in these operations specifications shall mean the holder of the operations specifications described in Part A Paragraph A001, and that the authorizations, limitations, and procedures described in the operations specifications shall apply to the foreign air carrier as well as to any of its officers, employees, or agents used in the conduct of its operation.

Global Positioning GLS is a differential GPS-based landing system providing both vertical and System (GPS) Landing lateral position fixing capability. The term GLS may also be applied to any System (GLS) GNSS-based differentially corrected landing system.

ILS-PRM Simultaneous close parallel instrument landing system (ILS) approaches are enabled through the implementation of special precision runway monitoring (PRM) equipment operated by ATC at certain airfields for specific runways, titled in 14 CFR Part 97 as “ILS PRM.” ILS PRM approaches are conducted between 4,299 and 3,000 feet parallel runway spacing. Runways 3,400 feet or greater apart utilize two parallel ILS courses, aligned with the runway centerlines (RCL). For runways spaced less than 3,400 feet, one ILS is offset 2.5° to 3.0°.

A-3 12/2/25 N 8900.754 Appendix A Term or Terms Definition Imported For purposes of the noise compliance rules, an imported airplane is a Airplane-Noise Stage 2 airplane of 75,000 pounds or more that was purchased by a U.S.

Compliance person from a non-U.S. owner on or after November 5, 1990. [Under the nonaddition rule (see 14 CFR Part 91, § 91.855), an imported airplane may not be operated to or from any airport in the contiguous United States. Such airplanes may be owned and registered by U.S. persons but are limited to operation outside the contiguous United States.]

Interchange An interchange arrangement is a method of providing operational flexibility Arrangement(s) and greater utilization of aircraft. Interchange arrangements permit a foreign air carrier to take or relinquish operational control of an aircraft at an airport located either in the U.S. or in the State of the foreign air carrier.

International Air Scheduled air service performed in airplanes for the public transport of Service passengers, mail, or cargo, between points in two or more countries.

International Air Air transportation performed in airplanes for the public transport of Transportation passengers, mail, or cargo, between points in two or more countries.

JAA JAR-OPS-1 Joint Aviation Authorities (JAA) Joint Aviation Requirements (JAR) operations (OPS). The European JAA adopted common operational guidance for all Member States in order to harmonize the rules within those States. The JAR-OPS-1, is part 1 of the operational agreement and comprises the operational requirements applicable to commercial air transportation fixed wing aircraft.

Land and Hold Short LAHSO is an acronym for “Land and Hold Short Operations.” These Operations (LAHSO) operations include landing and holding short of an intersecting runway, an intersecting taxiway, or some other designated point on a runway other than an intersecting runway or taxiway.

Localizer-Type See definition of simultaneous offset instrument approach (SOIA).

Directional Aid (LDA) PRM Large Aircraft A large aircraft for the purposes of these operations specifications means an aircraft with a seating capacity of more than 30 passengers and/or a maximum payload of more than 7,500 pounds.

Minimum Descent MDA(H) is the lowest altitude in an instrument approach procedure to Altitude (Height) which a descent is authorized on final approach or during circle-to-land (MDA(H)) maneuvering. The ‘altitude’ value is typically measured by a barometric altimeter; the ‘height’ value (H) is typically a radio altitude equivalent height above the touchdown zone (HAT) or height above airport (HAA) published elevation. The (H) is used only for advisory reference and does not necessarily reflect actual height above underlying terrain. [This definition is consistent with both current U.S. operator usage and ICAO international agreements.]

A-4 12/ 3 /25 N 8900.754 Appendix A Term or Terms Definition National Airspace The common network of U.S. airspace; air navigation facilities, equipment System and services, airports or landing areas; aeronautical charts, information and services; rules, regulations and procedures, technical information, and manpower and material. Included are system components shared jointly with the military (for definition of U.S. airspace, see “United States”).

Provisional Airport An airport approved for use by an air carrier for the purpose of providing scheduled service to a community when the regular airport serving that community is not available. Additionally, for operations with airplanes having a seating capacity of more than 30 passengers and/or a maximum payload of more than 7,500 pounds, an airport certificated under 14 CFR Part 139 or the military equivalent.

Receiver Autonomous RAIM is a function that considers the availability of satisfactory signal Integrity Monitoring integrity broadcasted from the particular GPS satellites used during a given (RAIM) flight. Onboard GPS navigators accomplish this automatically as the aircraft proceeds along its route. When insufficient signal integrity is detected, an alarm is provided to the flightcrew. Using the predictive RAIM software, flightcrews and dispatchers know in advance whether or not suitable GPS navigation will be available throughout the flight. This predictive information may also be determined during flight planning by contacting an FAA Flight Service Station (FSS).

A-5 12/ 3 /25 N 8900.754 Appendix A Term or Terms Definition Refueling Airport An airport approved as an airport to which flights may be dispatched only for refueling. Additionally, for operations with airplanes having a seating capacity of more than 30 passengers and/or a maximum payload of more than 7,500 pounds, an airport certificated under 14 CFR Part 139 or the military equivalent.

Regular Airport An airport approved under scheduled service to a community as the regular stop to that community. Additionally, for operations with airplanes having a seating capacity of more than 30 passengers and/or a maximum payload of more than 7,500 pounds, an airport certificated under 14 CFR Part 139 or the military equivalent.

Reliable Fix or A “reliable fix” or “reliable ground-based NAVAID fix” means station Reliable Ground-Based passage of a VOR, VOR/Tactical Air Navigation (VORTAC), or NDB. A NAVAID Fix reliable fix also includes a VOR/DME fix, an NDB/DME fix, a VOR intersection, an NDB intersection, and a VOR/NDB intersection provided course guidance is available from one of the facilities and the fix lies within the designated Operational Service Volumes of any facilities which define the fix.

Required Navigation A statement of navigation performance necessary for operations within a Performance (RNP) defined airspace.

Required Navigation Applies to aircraft equipped with inertial navigation systems (INS) or Inertial Performance (RNP) Reference Units (IRU) systems where those systems provide the means of Time Limit navigation to navigate to the degree of accuracy required by ATC. The FAA-approved time in hours (after the system is placed in navigation mode or is updated en route) that the specific INS or IRU make/model (M/M) can meet a specific RNP type on a 95 percent probability basis. It is used to establish the area of operations or routes on which the aircraft/navigation system is qualified to operate.

Required Navigation A value typically expressed as a distance in nautical miles (NM) from the Performance (RNP) intended position within which an aircraft would be for at least 95 percent of Type the total flying time. For example, RNP 4 represents a lateral and longitudinal navigation accuracy of 4 NM on a 95 percent basis. Note: Applications of RNP to terminal area and other operations may also include a vertical component.

RNAV (GPS) PRM Area Navigation (RNAV) (GPS) PRM approach that may be substituted for an ILS PRM or LDA PRM approach and is procedurally equivalent.

Runway In these operations specifications, the term “runway” in the case of land airports, water airports, and heliports, shall mean that portion of the surface intended for the takeoff and landing of land airplanes, seaplanes, or rotorcraft, as appropriate.

A-6 12/3/25 N 8900.754 Appendix A Term or Terms Definition Simultaneous Offset This operation comprises one ILS and one LDA with glide slope. The ILS is Instrument Approach aligned with its runway, but the LDA serving the second runway is offset (SOIA) (between 2.5° and 3°) from a parallel track. This offset permits simultaneous instrument approach operations to parallel runways spaced less than 3,000 feet apart, but no less than 750 feet. Because of the offset, this operation is also known as an SOIA.

Runway Visual Range An instrumentally derived value, based on standard calibrations, that (RVR) represents the horizontal distance a pilot will see down the runway from the approach end. It is based on the sighting of either High Intensity Runway Lights (HIRL) or on the visual contrast of other targets whichever yields the greater visual range. RVR, in contrast to prevailing or runway visibility, is based on what a pilot in a moving aircraft should see looking down the runway. RVR is horizontal visual range, not slant visual range. It is based on the measurement of a transmissometer made near the touchdown point of the instrument runway and is reported in hundreds of feet. RVR is used in lieu of RVV and/or prevailing visibility in determining minimums for a particular runway.

(1) Touchdown RVR. The RVR visibility readout values obtained from RVR equipment serving the runway touchdown zone.

(2) Mid-RVR. The RVR readout values obtained from RVR equipment located midfield of the runway.

(3) Rollout RVR. The RVR readout values obtained from RVR equipment located nearest the rollout end of the runway.

Runway Visibility The visibility determined for a particular runway by a transmissometer. A Value (RVV) meter provides a continuous indication of the visibility (reported in miles or fractions of miles) for the runway. RVV is used in lieu of prevailing visibility in determining minimums for a particular runway.

United States “United States,” in a geographical sense, means (1) the states, the District of Columbia, Puerto Rico, and the possessions, including the territorial waters, and (2) the airspace of those areas.

U.S. Special Airports “Special Airports,” for the purposes of these operations specifications, are airports which the FAA has determined due to such items as surrounding terrain, obstructions, or complex approach procedures are special airports requiring special airport qualifications, and are listed within DRS (specifically, within DRS—Flight Standards Administrative Information— Operations Safety System Documents (OPSS)—Document Number: OPSS Guidance PIC QA, as amended).

Surface Movement A SMGCS system consists of the provision of guidance to, and control or Guidance and Control regulation of, all aircraft, ground vehicles and personnel on the movement System (SMGCS) area of an aerodrome. Guidance relates to facilities, information and advice necessary to enable the pilots of aircraft or the drivers of ground vehicles to find their way on the aerodrome and to keep the aircraft or vehicles on the surfaces or within the areas intended for their use. Control or regulation A-7 12/ 3 /25 N 8900.754 Appendix A Term or Terms Definition means the measures necessary to prevent collisions and to ensure that the traffic flows smooth and freely.

VFR VFR station-referenced Class I navigation is any operation conducted within Station-Referenced the Operational Service Volumes of ICAO standard navigation aids under Class I Navigation visual flight rules (VFR) which uses nonvisual navigation aids (stations), such as VOR, VOR/DME, or NDB as the primary navigation reference. VFR station-referenced Class I navigation includes Class I navigation conducted on-airways and off-airway routings predicated on airways navigation facilities. These operations also include Class I navigation using an RNAV system, which is certificated for IFR flights over the routes being flown.

Wet Lease Any leasing or other agreement, other than a code-sharing arrangement, in which a lessor such as an air carrier leases an aircraft and at least one flight crewmember to another air carrier (the lessee) where the lessor retains operational control. A wet lease requires that a written agreement between the lessor and the lessee be executed by authorized officers of the two parties.

Either a copy of the lease agreement or a written memorandum of the terms of the lease agreement must be provided to the Administrator.

Wide Area WAAS has been developed to improve the accuracy, integrity, availability, Augmentation System and reliability of GPS signals. WAAS utilizes a fixed localized ground (WAAS) station to calculate GPS integrity and correction data, then broadcasts this information through the GPS satellites to GPS/WAAS users along with ranging signals. It is a safety critical system consisting of a ground network of reference and integrity monitor data processing sites which assess current GPS performance, as well as a space segment that broadcasts that assessment to GNSS users to support IFR navigation.
