Cabin Pressure

Recommended Posts

Hello everyone

 

I just read this fascinating article with the link below

 

Boeing is making a major change to its planes that could end jet lag as we know it

 

http://www.msn.com/en-us/money/companies/boeing-is-making-a-major-change-to-its-planes-that-could-end-jet-lag-as-we-know-it/ar-AAiJzzP?li=BBmkt5R&ocid=spartandhp

 

It says Boeing has lowered 787 Cabin pressure to 6000 feet versus the 777 which is set to 8000 feet because of the new composite material

 

The interesting part is that it is very beneficial to passengers and Jet lag on long flights

 

Is this modeled in the PMDG 777
I  can see FLT ALT and LDG ALT

 

But there no cabin pressure upon takeoff.

 

Thank You

This is a 787 feature, which of course is not modeled in the 777.  Select AIR to see cabin pressure numbers on upper DU. During takeoff, there is a small positive pressurization prior to rotation for a smooth transition to cabin climb. See FCOM 2.30.1

 

Also, the 787 does not use bleed for cabin pressurization.  It has two banks of four powerful electric fans.

That headline you quote is very misleading. It may reduce jet lag effects but it is never going to end it. Even if cabin pressure could be made to be sea level, time zone change would still have a significant effect people.

I Agree

 

The Heading said "ending jet leg" but the article says reducing the effects of Jet Lag and enhancing Oxygen %

There is no denying crossing time zones and sleep deprivation
