Optical equipment safety in fuel tanks

2018-11-15
WIP
ARP7977
This project aims to develop a framework of requirements which support safe installation and operation of optical devices within an aircraft fuel tank, specifically: 1: To determine optical power and energy limits which ensure safe operation of optical installations within an aircraft fuel tank over aircraft life and under all phases of flight, taking the limits provided in IEC 60079-28:20015 as a starting point. 2: To demonstrate optical and electrical power and energy equivalences, where possible. 3: To determine requirements for optical installations, including bonding and electrostatic discharge for non-conductive components such as optical fibres. 4: To provide guidelines for analysis of the hazards presented by the typical internal components of optical devices, such as failure modes of photo diodes and cells.

Nozzles and Ports – Gravity Fueling Interface Standards for Civil Aircraft

2012-01-03
CURRENT
AS1852D
This SAE Aerospace Standard (AS) defines the maximum allowable free opening dimensions for airframe fueling ports on civil aircraft that require the exclusive use of gasoline as an engine fuel, and the minimum free opening dimensions for airframe fueling ports on civil aircraft that operate with turbine fuels as the primary fuel type and with gasoline as the emergency fuel type. This SAE Aerospace Standard (AS) also defines the features and dimensions for airframe refueling ports on civil aircraft that require the exclusive use of turbine fuel as an engine fuel. In addition, this document defines the minimum fuel nozzle spout dimensions for turbine fuel ground service equipment, and the maximum fuel nozzle spout diameter for gasoline ground service equipment.
