2.2.3 Grade/product names Standard product names shall be used by all site staff to avoid confusion. It is not uncommon for customers to use unusual or abbreviated product names which can lead to confusion. This is particularly apparent where customers have operated internationally 1 or may only use one grade of fuel in their fleet and may not be aware of the importance of grade confirmation. Orders received from customers (or from instructions relayed via other members of staff) which do not use these product names shall be clarified. Orders such as “aviation fuel” or “gasoline”, etc., have the potential to cause the delivery of the incorrect grade of product. Refuelling staff shall only accept verbal fuel grade notification from the customer when there are wing grade decals fitted adjacent to the fuelling point of each aircraft fuel tank to be filled.
2.2.4 Use of wing decals Grade confirmation also occurs at the time of fuelling via the use of wing grade decals. The refuelling staff shall confirm, prior to commencement of fuelling, that the aircraft wing grade decal is the same grade as in the refuelling vehicle/equipment by observing the grade decal on the refuelling vehicle/equipment. Fuelling shall not commence unless they are the identical grade. Where wing grade decals are not fitted, the fuelling shall only progress when either: 1. The customer fits the wing decals or 2. The customer completes a written Fuel Order Form – refer to sections 2.3 and 2.4.
2.3 WING DECALS Wing decals should be designed as shown in Annex A and shall be readily available at all airport locations. Customers should be encouraged to fit and regularly replace wing decals. The use of wing decals provides an additional barrier against misfuelling by providing a form of grade confirmation immediately prior to the fuelling. The wing decals are colour-coded as are the overwing nozzles (section 2.8).
—Red background with white lettering – avgas.
— Black background with white lettering – jet fuel. Wing decals should be supplied to customers for application by the customer. Refuelling staff shall not apply the decals because this could compromise the grade confirmation step.
2.4 FUEL ORDER FORMS Fuel Order Forms are used to obtain written confirmation from the pilot/aircraft representative of the grade of fuel, quantity of fuel to be delivered into each aircraft fuel tank and the aircraft registration information. They are used in circumstances where verbal grade confirmation is not considered adequate. Fuel Order Forms shall be required where:
— The aircraft to be fuelled (overwing) is not fitted with wing decals.
— The wide jet nozzle spout is removed and replaced with a narrow spout to complete a fuelling of certain jet fuel type aircraft where the fuelling port will not accept the wide jet fuel spout.
— Fuelling of compression ignition piston (diesel) powered aircraft. An example of a Fuel Order Form is contained in Annex B. If customers provide written advice of grade requirements on their own order documentation, this shall not be considered sufficient as a replacement for the site Fuel Order Form. Fuel Order Forms should be designed so they cannot be confused due to any loss of colour-coding when photocopied.
2.5 SELECTIVE NOZZLE SPOUTS (OVERWING FUELLING) Grade selective nozzles use different sized spouts for avgas and jet fuel. Jet fuel nozzles utilize a large (wide) diameter spout while avgas nozzles utilize a smaller diameter spout. See SAE Aerospace Standard AS 1852 Nozzles and ports – Gravity fuelling interface standard for civil aircraft for details on both fuelling nozzle spout and aircraft filler port design requirements.API IP RP 1597 pdf download.API IP RP 1597:2006 pdf free download
