(e.g. in HLO office) VCR or DVD type player.
11.8.9.1 Equipment Specification
The established installation operator or vessel owner will probably have a contract in place with an approved ‘video briefing’ service provider to generally provide the playback equipment and briefing media that meets the legal requirements of the contracted helicopter operator(s). The media may be video laser disc (DVD) or videotape.
Helideck designers should establish with the installation operator or vessel owner which ‘briefing’ system and equipment should be provided. Where the installation operator or vessel owner has a number of established facilities / vessels and uses a particular helicopter operator and helicopter types to support his operation, this will dictate the media and equipment to be specified.
11.9 METEOROLOGICAL EQUIPMENT
11.9.1 Introduction
Flight crews involved in all types of aviation activity are heavily dependent upon comprehensive and accurate meteorological information to properly plan their flights and to maintain a high level of flight safety, whilst on the ground and in the air.
Offshore helicopter operations are equally as dependent, if not more so, on acquiring good meteorological information. It is because of the hostile environments that offshore helicopters encounter at sea and the remote locations of the landing sites; accurate information is required for the onshore departure airfield, for the general navigation area and at the offshore installation or vessel destination.
Historically, probably with the exception of those facilities equipped with automatic weather stations or staffed by meteorological specialists, offshore weather reports from installations and vessels have generally been of poor quality, often grossly inaccurate.
Therefore, properly calibrated instrumentation to enable accurate meteorological and flight information to be given to helicopter flight crews is an essential feature of helideck systems design for offshore operations.
NOTE: During offshore helideck inspections it is often found that meteorological instrument calibration certificates (e.g. anemometers and barometers) are unavailable or out of date. It is essential the initial calibration documents be passed to the Operator’s Maintenance Department to establish a suitable record keeping process during operations. A copy of these records should also be available on the installation or vessel.

11.9.3 Equipment Requirements
A windsock, airspeed indicator, air temperature probe, and barometric pressure instrumentation are the minimum equipment requirements for providing flight crews with essential offshore meteorological information.
Suitable equipment should be provided and the sensor / read out locations optimised to provide an accurate means for ascertaining:
