At high altitudes where commercial jetliners operate, bleed air is used to supply crew and passengers with fresh air at the right temperature. This bleed air is taken from the engine and mixed with recirculated cabin air. The bleed air is compressed to cabin pressure by the engine compressor, which is lubricated with synthetic oils, containing poisoning components. If the seals used are not a 100%, crew and passengers are at a risk of inhaling toxic air, leading to aerotoxic syndrome.

Other than the 787, all commercial aircraft, even the A350 (and most probably 777X) use bleed air for the cabin air supply. This is due to the fact that the engine compressor is overall the most efficient air compressor on-board jetliners. Besides, an additional compressor adds more weight, which translates in less payload and/or range.   In recent years, most efficiency improvements on aircraft… Continue reading
