of the rotorcraft;

to:

(b) the most rearward position of the tail rotor tip path plane or of the rotorcraft's fuselage.

Note   "D value" is a common design term used in ICAO Annex 14, Aerodromes, Volume II, Heliports. For ICAO documents, see section 1.07.

DVOR means the Doppler VOR.

earth mat area means the area of virgin ground that is directly underneath, and in immediate proximity to, a communications, navigation, surveillance site.

effective intensity, for a flashing light, is equal to the intensity of a fixed light of the same colour, which will produce the same visual range under identical conditions of observation.

elevation means the vertical distance of a point or a level, on or affixed to the surface of the Earth, measured from mean sea level.

exit taxiway means a taxiway connected to a runway to enable landing aeroplanes to turn off the runway.

facility has the same meaning as aerodrome facility.

FATO area means a final approach and take-off area of an aerodrome used for helicopter operations.

fixed light means a light having constant luminous intensity when observed from a fixed point.

FOD means foreign object debris, which may result in foreign object damage to an aircraft.

frangible object means an object of low mass designed to break, distort or yield on impact so as to present the minimum hazard to aircraft.

GBAS means a ground-based augmentation system comprised of a VHF data broadcast (VDB) antenna and (typically) 4 remote satellite measurement unit (RSMU) antennas, with each of these components:

(a) separately located; and

(b) performing specific functions; and

(c) with different siting requirements and restrictions.

GLS means GBAS landing system, and is a GNSS alternative to an ILS for approach and landing operations using a GBAS as the primary navigational reference.

GNSS means Global Navigation Satellite System.

gravel, for a surface, means that the surface is comprised of gravel and any binding additives but is not sealed.

hazard beacon means an aeronautical beacon used to designate a danger to air navigation.

HF means the high frequency band, that is radio frequencies in the range 3 000 to 30 000 kHz.

holding bay is a defined area where aircraft can be held or bypassed to facilitate efficient surface movement of aircraft.

Note    Generally, such an area is offset from the taxiway so that clearance for passing aircraft is maintained.

homogeneous runway surface means a runway surface that has a consistent surface finish across its full width.

Note   A non-homogeneous runway surface means a runway surface that has different surface finishes across its full width. A non-homogeneous runway surface may result in differing friction, loading, and wet weather characteristics. Thus, it may limit the operations of some aircraft
