This document is applicable to commercial and military aircraft fuel quantity indication systems. It is intended to give guidance for system design and installation. It describes key areas to be considered in the design of a modern fuel system, and builds upon experiences gained in the industry in the last 10 years.
This guidance document has been produced in an effort to record best practice in fuel gauging system design and indicate those things which should be considered in the design of a new fuel gauging system in order to achieve an accurate and reliable fuel quantity indicating system (FQIS). It is also intended to capture changes in design practice since ARINC 611 1 was issued in 1999.
