EFFECTIVE DATE/TIME —

FAA and Canada: Aeronautical information in the U.S. and its territories is generally effective on the designated effective date at 09:01 Coordinated Universal Time (UTC). The effective time applies to airspace, airways and flight procedures. It allows for implementation between 01:00 and 06:00 local standard time in the U.S. Local authorities may change the date or time of implementation due to local operational considerations. Check NOTAMs and contact local ATC for information.

International: The International Civil Aviation Organization (ICAO) guidance specifies that aer onautical information should be effective on the designated effective date at 00:00 Coordinated Universal Time (UTC). However national and local authorities often change the effective time to allow for implementation during the local night or at other times due to local operational consid erations. When an effective time other than 00:00 UTC is used, ICAO requires that it be pub lished in the official Aeronautical Information Publication (AIP) of the country. Check NOTAMs and contact local ATC for information.

ELEVATION

— The vertical distance of a point or a level, on or affixed to the surface of the earth, measured from mean sea level.

EMERGENCY PHASE

— A generic term meaning, as the case may be, uncertainty phase, alert phase or distress phase.

ENGINEERED MATERIALS ARRESTING SYSTEM (EMAS) ★

— High-energy-absorbing material located in the runway overrun that is designed to crush under the weight of an aircraft as the material exerts deceleration forces on the aircraft landing gear.

ENROUTE FLIGHT ADVISORY SERVICE (FLIGHT WATCH)

— A service specifically designed to provide, upon pilot request, timely weather information pertinent to the type of flight, intended route of flight, and altitude. The FSSs providing this service are indicated on Jeppesen Enroute and Area charts.

ESTIMATED ELAPSED TIME

— The estimated time required to proceed from one significant point to another.

ESTIMATED OFF-BLOCK TIME

— The estimated time at which the aircraft will commence movement associated with departure.

ESTIMATED TIME OF ARRIVAL

— For IFR flights, the time at which it is estimated that the air craft will arrive over that designated point, defined by reference to navigation aids, from which it is intended that an instrument approach procedure will be commenced, or if no navigation aid is associated with the aerodrome, the time at which the aircraft will arrive over the aerodrome. For VFR flights, the time at which it is estimated that the aircraft will arrive over the aerodrome.

EXPECTED APPROACH TIME

— The time at which ATC expects that an arriving aircraft, follow ing a delay, will leave the holding point to complete its approach for a landing.

NOTE: The actual time of leaving the holding point will depend upon the approach clearance.

EXTENDED OPERATION (ETOPS) ★

— Any flight by an aeroplane with two turbine power-units where the flight time at the one power-unit inoperative cruise speed (in ISA and still air conditions), from a point on the route to an adequate alternate aerodrome, is greater than the threshold time approved by the State of the Operator.

FAA AIR CARRIER OPERATIONS SPECIFICATIONS

— Document issued to users operating under Federal Aviation Administration Regulations (FAR) Parts 121, 125, 127, 129, and 135. Operations Specifications are established and formalized by FARs. The primary purpose of FAA Air Carrier Operations Specifications is to provide a legally enforceable means of prescribing an authorization, limitation and/or procedures for a specific operator. Operations Specifications are subject to expeditious changes. These changes are usually too time critical to adopt through the regulatory process.

FEEDER FIX

— The fix depicted on instrument approach procedure charts which establishes the starting point of the feeder route.

FEEDER ROUTE ★

— Routes depicted on instrument approach procedure charts to designate routes for aircraft to proceed from the enroute structure to the initial approach fix (IAF).

FILED FLIGHT PLAN (FPL)

— The flight plan as filed with an ATS unit by the pilot or a designa ted representative, without any subsequent changes.

FINAL APPROACH COURSE

— A bearing/radial/track of an instrument approach leading to a runway or an extended runway centerline all without regard to distance.

FINAL APPROACH (ICAO) ★

— That part of an instrument approach procedure which commences at the specified final approach fix or point, or where such a fix or point is not specified,

a. at the end of the last procedure turn, base turn or inbound turn of a racetrack procedure, if specified; or

b. at the point of interception of the last track specified in the approach procedure; and ends at a point in the vicinity of an aerodrome from which:

1. a landing can be made; or

2. a missed approach procedure is initiated.

FINAL APPROACH AND TAKE-OFF AREA (FATO)  

— A defined area over which the final phase of the approach manoeuvre to hover or landing is completed and from which the take-off manoeuvre is commenced. Where the FATO is to be used by performance Class 1 helicopters, the defined area includes the rejected take-off area available.

FINAL APPROACH FIX (FAF)

— The fix from which the final approach (IFR) to an airport is executed and which identifies the beginning of the final approach segment. It is designated in the profile view of Jeppesen Terminal charts by the Maltese Cross symbol for non-precision approaches and by the glide slope/path intercept point on precision approaches. The glide slope/path symbol starts at the FAF. When ATC directs a lower-than-published Glide Slope/Path Intercept Altitude, it is the resultant actual point of the glide slope/path intercept.

FINAL APPROACH FIX (FAF) (AUSTRALIA)

— A specified point on a non-precision approach which identifies the commencement of the final segment. The FAF is designated in the profile view of Jeppesen Terminal charts by the Maltese Cross symbol.

FINAL APPROACH FIX (FAF) OR POINT (FAP) (ICAO)

— That fix or point of an instrument approach procedure where the final approach segment commences.

FINAL APPROACH — IFR (USA)

— The flight path of an aircraft which is inbound to an airport on a final instrument approach course, beginning at the final approach fix or point and extending to the airport or the point where a circling approach/circle-to-land maneuver or a missed approach is executed.

FINAL APPROACH POINT (FAP) (USA)

— The point, applicable only to a non-precision approach with no depicted FAF (such as an on-airport VOR), where the aircraft is established inbound on the final approach course from the procedure turn and where the final approach descent may be commenced. The FAP serves as the FAF and identifies the beginning of the final approach segment.

FINAL APPROACH POINT (FAP) (AUSTRALIA)

— A specified point on the glide path of a preci sion instrument approach which identifies the commencement of the final segment. NOTE: The FAP is co-incident with the FAF of a localizer-based non-precision approach.

FINAL APPROACH SEGMENT (FAS)

— That segment of an instrument approach procedure in which alignment and descent for landing are accomplished.

FLIGHT CREW MEMBER

— A licensed crew member charged with duties essential to the operation of an aircraft during flight time.

FLIGHT DOCUMENTATION

— Written or printed documents, including charts or forms, containing meteorological information for a flight.

FLIGHT INFORMATION CENTRE

— A unit established to provide flight information service and alerting service.

FLIGHT INFORMATION REGION (FIR, UIR)

— An airspace of defined dimensions within which Flight Information Service and Alerting Service are provided.

FLIGHT INFORMATION SERVICE (FIS)

— A service provided for the purpose of giving advice and information useful for the safe and efficient conduct of flights.

FLIGHT LEVEL (FL)

— A surface of constant atmospheric pressure which is related to a specific pressure datum, 1013.2 hectopascals (hPa), and is separated from other such surfaces by spe cific pressure intervals.

NOTE 1: A pressure type altimeter calibrated in accordance with the Standard Atmosphere:

a. when set to a QNH altimeter setting, will indicate altitude;

b. when set to a QFE altimeter setting, will indicate height above the QFE reference datum;

c. when set to a pressure of 1013.2 hectopascals (hPa), may be used to indicate flight levels.

NOTE 2: The terms “height” and “altitude,” used in NOTE 1 above, indicate altimetric rather than geometric heights and altitudes.

FLIGHT PATH MONITORING

— The use of ATS surveillance systems for the purpose of providing aircraft with information and advice relative to significant deviations from nominal flight path, including deviations from the terms of their air traffic control clearances.

NOTE: Some applications may require a specific technology, e.g. radar, to support the function of flight path monitoring.

FLIGHT PLAN

— Specified information provided to air traffic services units, relative to an inten ded flight or portion of a flight of an aircraft.

NOTE: Specifications for flight plans are contained in ICAO Rules of the Air, Annex 2. A Model Flight Form is contained in ICAO Rules of the Air and Air Traffic Services, PANS-RAC (Doc 4444), Appendix 2 and ATC section.

FLIGHT VISIBILITY

— The visibility forward from the cockpit of an aircraft in flight.

FLIGHT WATCH (USA)

— A shortened term for use in air-ground contacts to identify the flight service station providing Enroute Flight Advisory Service; e.g., “Oakland Flight Watch.”

FLOW CONTROL

— Measures designed to adjust the flow of traffic into a given airspace, along a given route, or bound for a given aerodrome, so as to ensure the most effective utilization of the airspace.

FORECAST

— A statement of expected meteorological conditions for a specified time or period, and for a specified area or portion of airspace.
