After 9 years on the Bae146, I await with some trepidation the medical effects of operating this quirky aircraft.
Working for an airline which was one of the first to use the type, it was a common pracice to start the APU some time before boarding so that when the packs were initiated we could observe the arrival in the aft cabin of a cloud of blue smoke which gradually dispersed.
Pax then boarded into a supposedly "clean" cabin, though one can only guess at the dosage rate to the unfortunate cabin crew performing their normal preflight checks. The issue was frequently highlighted as a defect in the tech log with the standard Not
Fixed annotation by the engineers.
In the subsequent descents (APU NOT operating), the waft of sweaty socks occurred at around 8,000ft aircraft altitude as reliably as an auto altitude callout. The same "rectification" writeup would be observed.
Try getting hold of a copy of "Toxic Airlines" by Tristan Lorraine if you want a cracking good yarn with a suitable ending for more info on the topic. The book gives a very good explanation as to why we, as actual and potential vicims of this mass poisoning, are being kept in the dark, along with the mushrooms!
I shall now reflect on why I use this posting name..............
