DocumentBAR 14 Volume I - AerodromesVersion2.1Note 1. The number of movements in the mean busy hour is the arithmetic mean over theyear of the number of movements in the daily busiest hour.Note 2. Either a take-off or a landing constitutes a movement.Aeronautical Beacon: An aeronautical ground light visible at all azimuths, eithercontinuously or intermittently, to designate a particular point on the surface of the earth.Aeronautical Ground Light: Any light specially provided as an aid to air navigation, otherthan a light displayed on an aircraft.Aeronautical Study: A study of an aeronautical problem to identify possible solutionsand select a solution that is acceptable to the Brunei DCA without degrading safety.Aeroplane Reference Field Length: The minimum field length required for take- off atmaximum certificated take-off mass, sea level, standard atmospheric conditions, still air andzero runway slope, as shown in the appropriate aeroplane flight manual prescribed by thecertificating authority or equivalent data from the aeroplane manufacturer. Field lengthmeans balanced field length for aeroplanes, if applicable, or take-off distance in other cases.Note: ICAO Annex 14, Volume 1, Attachment A, Section 2 provides information on the concept ofbalanced field length and the ICAO Airworthiness Manual (Doc 9760) contains detailed guidance onmatters related to take-off distance.Aircraft Classification Number (ACN): A number expressing the relative effect of anaircraft on a pavement for a specified standard subgrade category.Note: The aircraft classification number is calculated with respect to the centre of gravity (CG) positionwhich yields the critical loading on the critical gear. Normally the aftmost CG position appropriate tothe maximum gross apron mass is used to calculate the ACN. In exceptional cases the forward mostCG position may result in the nose gear loading being more critical.Aircraft Stand: A designated area on an apron intended to be used for parking an aircraft.Alternative Means of Compliance: Alternative means of compliance are those thatpropose an alternative to an existing Acceptable Means of Compliance (AMC) or those thatpropose new means to establish compliance with the BAR for which no associated AMChave been adopted by the Brunei DCA.Apron: A defined area, on a land aerodrome, intended to accommodate aircraft forpurposes of loading or unloading passengers, mail or cargo, fuelling, parking ormaintenance, including any apron taxiways and aircraft stand taxilanes.Apron Management Service: A service provided to regulate the activities and themovement of aircraft and vehicles on an apron.Balked Landing: A landing manoeuvre that is unexpectedly discontinued at any pointbelow the obstacle clearance altitude/height (OCA/H).Barrette: Three or more aeronautical ground lights closely spaced in a transverse line sothat from a distance they appear as a short bar of light.Calendar: Discrete temporal reference system that provides the basis for defining temporalposition to a resolution of one day (ISO 19108).Capacitor Discharge Light: A lamp in which high-intensity flashes of extremely shortduration are produced by the discharge of electricity at high voltage through a gas enclosedin a tube.Certified Aerodrome: An aerodrome whose operator has been granted an AerodromeCertificate.01 Dec 2019Uncontrolled when printedPage 10 of 235

This includes problems and meeting changing demands.Competence in Application: The ability of individuals to demonstrate consistently that theperformance outcomes defined for their role can be achieved to the standard expected in theworkplace.Competent in Acquisition:The ability of individuals to demonstrate that they can apply thelearning acquired in the workplace to the standards defined in the performance criteria fortheir role.Contaminated Runway: A runway is contaminated when more than 25 per cent of therunway surface area (whether in isolated areas or not) within the required length and widthbeing used is covered by:Water or slush more than 3 mm (0.125 in) deep;Loose snow more than 20 mm (0.75 in) deep; orCompacted snow or ice, including wet ice.Cyclic Redundancy Check (CRC): A mathematical algorithm applied to the digitalexpression of data that provides a level of assurance against loss or alteration of data.Data accuracy: A degree of conformance between the estimated or measured value andthe true value.Data quality: A degree or level of confidence that the data provided meet therequirements of the data user in terms of accuracy, resolution, integrity (or equivalentassurance level), traceability, timeliness, completeness and format.Date integrity (assurance level): A degree of assurance that an aeronautical data and itsvalue has not been lost or altered since the origination or authorized amendment.Datum: Any quantity or set of quantities that may serve as a reference or basis for thecalculation of other quantities (ref.
