EDXJ schrieb:3.2.2 Helicopter traffic zones (HTZ) and helicopter protection zones (HPZ)
Was ich mich bzgl Ameland frage: Was ist noch mal eine HPZ (Ameland HPZ 0-2000ft)?
HTZs: an area established around a platform or rig with a helideck to safeguard helicopter approaches and departures. A HTZ extends vertically from MSL up to and including 2000 ft AMSL and is horizontally defined as a circle of 5 NM radius, unless otherwise specified.
HPZs: an area established around two or more platforms and/or rigs to safeguard helicopter approaches, departures, and extensive uncoordinated inter-platform traffic. A HPZ extends vertically from MSL up to and including 2000 ft AMSL. A HPZ is horizontally defined as the smallest area encompassing the HTZ(s) of the platforms and/or rigs, including an instrument approach area.
On the basis of assignment to concession holders, some HPZs have been divided in sectors (see chart ENR 6-3.1), through which a more effective flight information service will be possible.
Note- when a part of a HPZ and/or HTZ is situated below controlled airspace with a lower limit below 2000 ft AMSL, the upper limit of that area within the HPZ or HTZ will be equal to the lower limit of the aforementioned controlled airspace.
- the lateral limits of HTZs located in a HPZ are restricted to the lateral limits of the HPZ.
Die HPZ Ameland ist H24 aktiv.
