Six of these aircraft reached their target after at least 16 of these events, while the other 10 had to land at a divert airport.The indicator will display a different amount of fuel than what is actually present in the centre wing tank as a result of the flaw’s incorrect fuel-density calculation. The change was made in response to at least 25 instances in which there was a discrepancy between the amount of fuel indicated by the aircraft’s centre tank and the amount lifted from refuelling trucks, and each time the crew received a message stating that there was “fuel disagree” or “insufficient fuel” within three hours of takeoff. The Global Aviation Fuel Quantity Indicating System market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.īoeing modifying 777 fuel indicator after in-flight discrepancy incidents.After the identification of a fuel discrepancy issue involving the centre wing tank, Boeing is creating a retrofit for the 777 passenger and freighter aircraft. GLOBAL AVIATION FUEL QUANTITY INDICATING SYSTEM MARKET SIZE AND FORECAST For this application, resistive-based sensors are most commonly used. It is intended to give guidance for system design and installation. Group 2: PART 3: AIRPLANES WITH HONEYWELL FUEL QUANTITY INDICATING SYSTEM (FQIS) - FQIS. This document is applicable to commercial and military aircraft fuel quantity indication systems. To measure fuel level, various methods such as resistive film, discrete resistors, capacitive, and ultrasonic are used. Put the airplane back to a serviceable condition. In all automobiles, a fuel level sensor (FLS) is used to indicate fuel level. By varying a precisely controlled electrical signal, both of these systems provide fuel quantity information. The purpose of the Fuel Quantity Measuring System is to show the pilot a visual representation of the amount of usable fuel currently stored in the aircraft’s fuel tanks. The subsystem most dependent on the wing geometry is the fuel quantity indication (FQI) system. GLOBAL AVIATION FUEL QUANTITY INDICATING SYSTEM MARKETįuel tank and engine feed tank contents, as well as low level alerts, are likely to be included in the “Fuel Quantity Indicating System,” which is present on modern multi-engined aircraft. the aircraft to the airframe system level, with a higher level of detail than is traditionally the case 7.
