The objective of this Handbook is to establish the procedures, guidelines, and standards for the Department of the Interior (DOI) Aviation Fuel Quality Control Program. This should help assure the delivery of the correct type and grade of uncontaminated fuel into aircraft utilized for DOI aviation operations.

This handbook provides basic information on the properties and characteristics of aviation fuels along with general information on the standards, equipment, and operating principals related to the handling of these fuels at Navy and Marine Corps activities. It is designed to supplement the NATOPS AIRCRAFT REFUELING MANUAL, NATOPS 00-80T-109, by providing background information and guidance on the requirements and procedures contained in the NATOPS Manual. The contents of this handbook are limited to technical and operational information of a general nature. Specific operating procedures and equipment requirements are contained in the NATOPS AIRCRAFT REFUELING MANUAL, NATOPS 00-80T-109. Accounting and stock control procedures are not included in this handbook or the NATOPS Manual. There are basically two different types of aircraft fuels in use at Navy and Marine Corps air activities - turbine engine fuels and aviation gasolines (AVGAS). A knowledge of some of the basic properties and characteristics of these fuels is necessary in understanding the importance of delivering the proper fuel to the aircraft. Such knowledge is also valuable in understanding the need for safety and caution in handling aviation fuels.
