Jet A-1 Quality on board of Accident flight British airways BA -038 - part 7

Jet A-1 Quality on board of Accident flight British airways BA -038 -  part 7 This is in continuation of “ British Airways flight BA-038accident and aviation fuel quantity aspects - part 6 ”, a blog series for understanding Aviation turbine fuel’s role in modern civil flights specially  behaviour of water in fuel  to mitigate it’s adverse effects during flight, including at high altitude where water will turn into ice. Last part gave a brief idea on fuel system, storage tanks, pumps, fuel feed manifold, fuel tank vents, fuel filters, fuel oil heater, fuel flow meter etc Fuel Origin and Quality on board of BA-038. Aviation Fuel refuelled was Jet A-1 originated from South Korea and was shipped to Tianjin, China and transferred to the airport bulk fuel storage facility at Beijing. Fuel was certified to meet  Chinese specification GB6537 , issued by China’s National Technology Supervisory Bureau. The GB6537 standard covers “ No.3 Jet Fuel ” which is basically equivalent

British Airways flight BA 38 accident and aviation fuel quantity aspects - part 6 This is in continuation of “British Airways flight BA 38 accident and Aircraft Jet A-1 fuel System - part 5”, a blog series for understanding Aviation turbine fuel’s role in modern civil flights specially  behaviour of water in fuel  to mitigate it’s adverse effects during flight, including at high altitude where water will turn into ice. Last part gave a brief idea on fuel system, storage tanks, pumps, fuel feed manifold, fuel tank vents, fuel filters, fuel oil heater, fuel flow meter etc From fuel supplier’s perspective, it is interesting to know the aircraft systems which manage fuel quantity. This part gives idea on aviation fuel tanks, fuel quantity measurements and display to crew and related aspects on board thru B-777 British Airways BA 038 accident story. The aircraft landed at Beijing at 0009 hrs on 17 January, 2008 from London with 4,100 kg in the right main, 4,000 kg in the left

British Airways flight BA 38 accident and Aircraft Jet A-1 fuel System - part 5 This is in continuation of  " British Airways flight BA 38 accident and Jet A-1 fuel temperature - part 4"  a blog series for understanding Aviation turbine fuel’s role in modern civil flights specially  behavior of water in fuel  to mitigate it’s adverse effects during flight, including at high altitude where water will turn into ice. From fuel supplier’s perspective, it is interesting to know the aircraft fuel system which handles water (sumps in tanks, water scavenger pumps), removes external impurities from fuel (strainers-filters), fuel temperature indicators, fuel heater etc. An aircraft fuel system enables fuel to be loaded, stored, managed and delivered to the propulsion system of an aircraft. Fuel systems differ greatly from aircraft to aircraft due to the relative size and complexity of the aircraft in which they are installed.  In a modern, multi-engine passenger or car

British Airways flight BA 38 accident and Jet A-1 fuel temperature - part 4 This is in continuation of  “ British Airways flight BA 038 flight altitude and Cold fuel Management - part 3 ”, a blog series for understanding Aviation turbine fuel’s role in modern civil flights specially  behavior of water in fuel  to mitigate it’s adverse effects during flight, including at high altitude where water will turn into ice. The article and next parts covers fuel temperature  at various stages during flight journey, from Beijing refuelling to London after crash remaining fuel in aircraft tanks, and gives insight of fuel temperature measuring and controlling systems for avoiding ice adverse impacts.
