>The 787 itself is a big factor in my comfort. The strength of the carbon fibre fuselage means that the cabin altitude is set to 5000 feet instead of the normal 8000 feet in other aircraft, and the air is recirculated more often I believe, which leads to less fatigue and high altitude problems.
It's also more humid. Since the body isn't aluminum, they dont have to worry about it degrading so much from humid air.
- dvdkhlng 7y agoI think it's not so much a question of material degradation due to humidity. The problem is low outside air temperature (-50 deg celsius?) leading to low inside surface temperature leading to condensation which is also a problem WRT cables routed through cabin walls. Maybe inside surface temperature on carbon fibre is higher (better insulation), allowing for higher dew point [1], thus higher humidity levels.
