I've done work in this area. It's really hard to monitor the bleed air because the required equipment is very expensive and degrades fairly rapidly over time due to contamination from random stuff. For example, when you sit behind another airliner waiting, the engine ingests exhaust and that causes lots of (mostly harmless) stuff to enter the bleed air which you then need to worry about getting in your sensor.
- amluto 7y agoMaybe this is a hint that aircraft that are behind other aircraft should recirculate their cabin air instead of adding outside air until they’re somewhere less stinky.
- AWildC182 7y agoI'm willing to bet that would be worse. Try to visualize the amount of air volume per passenger on a fully loaded A321. More than a few minutes of that would probably make the cabin unbearably stuffy.
- rainbowzootsuit 7y agoProbably about 5cfm/person + 0.12cfm/sqft based on typical ASHRAE Standard 62.1 numbers. Although they don't have "Airliner Cabin" as a space type, my guess is based on sedentary 1met people and a rather high VOC load from the amount of luggage and upholstery is in an Airliner Cabin. Might be higher on the cfm/sqft.
