longitudinal separation Separation between aircraft at the same altitude, expressed in units of time or distance along track. Fr: espacement longitudinal long radius exit Other expression for: high speed taxiway long range air navigation An electronic navigational system by which hyperbolic lines of position are determined by measuring the difference in the time of reception of synchronized pulse signals from two fixed transmitters. LORAN A operates in the 1750-1950 kHz frequency band. LORAN C and D operate in the 90-110 kHz frequency band. . abbreviation: LORAN Fr: navigation aérienne longue portée LORAN Abbreviation for: long range air navigation Fr: LORAN loss of separation An occurrence in which less than the authorized minimum existed or in which the minimum was not assured. Fr: perte d’espacement low altitude alert system U.S.: An automated function of the TPX-42 that alerts the controller when a Mode C transponder-equipped aircraft on an IFR flight plan (FP) is below a predetermined minimum safe altitude. If requested by the pilot, LAAS monitoring is also available to VFR Mode C transponder-equipped aircraft. . abbreviation: LAAS low approach An approach over an airport or runway following an instrument approach procedure (IAP) or VFR approach, including the overshoot manoeuvre, where the pilot intentionally does not make contact with the runway. Fr: approche basse altitude low frequency The frequency band between 30 and 300 kHz. . abbreviation: LF Fr: basse fréquence low level air route Within low level uncontrolled airspace, a route extending upwards from the surface of the earth and for which ATC service is not provided. Fr: route aérienne de l’espace inférieur low level airspace All airspace within the Canadian Domestic Airspace (CDA) below 18 000 ft ASL. . abbreviation: LLA Fr: espace aérien inférieur low level airway Within controlled low level airspace, a route extending upwards from 2200 ft above the surface of the earth and for which ATC service is provided. Fr: voie aérienne de l’espace inférieur low level autorotation An autorotation manoeuvre that commences at an altitude well below the aerodrome traffic circuit and that is used primarily for tactical military training. Fr: autorotation à basse altitude low level fixed RNAV route In low level airspace, a prescribed area navigation track between specified fixes. For routes in controlled low level airspace, the airspace extending upwards from 2200 ft above the surface of the earth within the following specified boundaries: (a) The primary route width is 10 mi. on each side of the centreline prescribed for such a route.
