What does it mean by lower pressure?. The only thing I can make sense out of is the cabin pressure vs the outside pressure. Less cabin pressure means less breathable air to me.
and lower pressure altitude means to me that you are flying at higher altitudes (an aircraft performance issue)
What am I missing ?
What the post was inferring is that the A350 has an option to be pressurized to a lower altitude inside the cabin. I don’t know the specifics on the A350 but on the 787 the cabin is pressurized to about 5,000-6,000 feet above sea level when at cruising altitude while on other older model airliners the cabin altitude is typically around 8,000 feet when the aircraft is at cruising altitude.
The lower cabin altitude on the 787 and A350 is supposed to help reduce jet lag and create a more comfortable onboard atmosphere for passengers.
