Homing receivers
Three types of homing (direction finding) receivers are available to assist in locating missing aircraft or personnel transmitting on emergency frequencies. 1) Sonar Pinger homers are used for locating a submerged aircraft transmitting with a sonar pinger. 2) ELT and beacon homers are used for locating a downed aircraft on land or floating in water.
3) Radars on aircraft or vessels can be used to locate SARTs (see above). If not available for either water or land in the country of operation, then these homing devices should be added as a contract specification or included in Company owned equipment.
Rescue hoists
The role of rescue hoists for Search & Rescue purposes in emergency response planning (ERP) should be carefully evaluated and a Risk Analysis completed by the OGP Member’s Health, Safety & Environment (HSE) staff with the assistance of its Aviation Advisor.
When considering rescue hoisting as a secondary role for helicopters, consideration should be given to the overall ability of the operator to perform competently and to complete periodic training to support the hoisting role given the parameters established in the ERP. Such programmes for over water rescue should include training over open water without visual reference to land.
It may be more practicable to provide a linked life raft system as noted in paragraph 12.5.5 and Appendix 12, Section 5 rather than to provide a rescue hoist if the Risk Analysis supports this deci-sion. Nonetheless, both are demanding tasks when conducted over open water and periodic training must be undertaken.
Warm-up clothing
Suitable clothing that rescued personnel can change into as soon as practicable after rescue, such as sweat suits or blankets should be located in a waterproof container with other rescue equipment.
12.5 Survival equipment
12.5.1 Survival kits
All aircraft should carry safety equipment and survival kits that, as a minimum, comply with local civil aviation authority or regulation.
When considered necessary, the Company may request additional equipment subject to the operat-ing environment. The items contained in survival kits should be appropriate for the geographical location and climatic conditions; for example, offshore, arctic, jungle or desert.
The capacity of each survival kit should be proportionate to the number of persons carried in the aircraft.
Over-water operations require special considerations for safety and survival equipment such as life jackets, immersion suits and emergency rafts.
12.5.2 Life rafts
All life rafts should be equipped with an emergency radio/beacon. All life rafts should be equipped with an approved offshore survival kit and be attached to the raft with a lanyard. a) Exception -Single piloted helicopter survival kits may be located separately in the front cabin area to provide easy access by the pilot or front seat passenger. b) See also paragraphs 10.3.2 and 12.4.2 for additional details. The following life raft requirements are recommended: a) Helicopters having a seat capacity for 10 or more passengers should have two life rafts; each should be certified for 50% overload to enable any one life raft to be used by all occupants. b) Helicopters having a seat capacity for 9 or less passengers should have a minimum of one life raft certified to carry all occupants. c) Where available by helicopter model, externally mounted life rafts are preferred over inter-nally mounted.
12.5.3 Life jackets
Approved types
Only those life jackets that are manufactured to an aviation authority approved TSO and certifi-cated for use by the regulatory authority should be used. The following points should be noted:
a) Permanently buoyant vests should not be worn or provided to occupants on aircraft flights because these types significantly hinder egress from a submerged helicopter or aeroplane. This is the same reason why life jackets should never be inflated until well outside of the helicopter or aeroplane cabin.
