11.7.4.5 Miscellaneous Provisions
Fuel Quality
System design and quality control procedures should be stringently followed in order to ensure that fuel dispensed is fit for aviation purposes.
Materials of Construction
Material selection is very important to ensure that system integrity and aviation fuel cleanliness is always maintained. For this reason stainless steel piping and components are used throughout.
Aircraft Bonding Cable and Reel
The dispenser must be equipped with a securely mounted, retractable bonding cable (hand, pneumatic or electric powered) with a substantial insulated crocodile clip and quick disconnect plug incorporated into the cable at the aircraft end (in the event that the helicopter departs with the bonding cable still attached).  See Figure
11.27.
Refuelling Couplings
Pressure and open line fuel delivery nozzles should be provided.
System Colour Coding and Identification Markings
Jet-A1 fuel system components should be correctly marked with the appropriate vessel and piping product identification codes.  Additionally, appropriate Hazchem labels should be sited at fuel storage and dispenser locations.  See Figure 11.28 and 11.29.

11.8 COMMUNICATIONS EQUIPMENT
11.8.1 Introduction
Communications equipment is a key part of helicopter operations in an offshore environment.  In the UK, there are specific radio and navigation equipment requirements for supporting offshore helideck operations. Meteorological data (See Section 11.9) is also an essential part of the information communicated to flight crews during offshore helicopter operations.  The procedures and practical mechanisms for helicopter communications should be considered in conjunction with the equipment arrangements provided for aeronautical communications.
During a design and construction project aeronautical communications equipment will often be specified as part of a total package for the installation or vessel.  It is therefore important for helideck designers dealing with the aeronautical communications requirement to liase with project and / or company communication specialists.  This should ensure that efficient and approved system coverage is obtained.
Guidance and approval for all items of air-band radio equipment, etc. should be obtained from the Air Traffic Safety Standards Department (ATSSD) of the CAA at Gatwick. It should also be noted that all aeronautical frequencies (NDB and R/T) are subject to international protocols and are controlled in the UK solely by ATSSD.
Applications to CAA ATSSD will be required for using the specified equipment and for frequency allocations.  This procedure requires completion and submission of official forms to CAA ATSSD and the process takes a considerable time to conclude. This time period should be built into the project programme.
