Talk:Environmental control system

message: I was just wondering about this:
- Boeing and Airbus jetliners supply constant flow per unit length of the cabin.
- Airflow into the fuselage is approximately constant, and pressure is maintained by varying the opening of the "Out Flow Valve" (OFV). Most modern jetliners have a single OFV located near the bottom aft end of the fuselage
If both are true, air inserted in the front of the cabin would have to make its way to the back, resulting in a net front-to-aft airflow... and air would have passed by more passangers towards the aft of the cabin.
Is this true, or is air vented over the entire length of the cabin and then transported to the back of the fuselage using conduits?
- 
On a sidenote, i always believed this net flow used to be the reason that smoking seats where always on the back rows (and first class is up front). Any insights?
Comments:
In principle, these comments are correct. 
Air is vented over the entire length of the aircraft (think of all the gaspers above the seats in the lugage bins). 
Please note however that the gaspers (where the air flows from the ventilation ducts into the cabin) are located near the ceiling. The slots, where the air exists the passenger area and goes into the cargo bays, are located near the floor (in the DADO panles). So the air flows front-to-aft AND downwards. This results in most smelly air flowing downwards before it reaches the passengers in the back. 
To avoid any nicotine fumes reaching the forward compartment, the smoking area is loacted in the back. 
First Class is located in the front to assure that first class passengers can board the area last (in most cases only the front door is used for boarding) and they receive their meals and service first (near to the galley and crew area).  —Preceding unsigned comment added by 87.211.57.138 (talk) 09:44, 14 April 2008 (UTC)
thread_title:  Air quality front to aft? 

message: "The new airliners such as the Airbus A380 and Boeing 787 will have lower maximum cabin altitudes which help in fatigue reduction during flights."
I think this argument is incorrect. Lower maximum cabin altitude means higher minimum cabin pressure. This higher minimum cabin pressure results is a higher pressure difference between cabin and outside. 
With new composites used in the A380 and B787, the structure can handle these bigger loads, since less rivets are used and more glued connections (les stress peaks). 
I think the argument should read:
The new airliners such as the Airbus A380 and Boeing 787 will have lower maximum cabin altitudes because of their composite structures and theirfore their lower fatigue damage growth.
What do you think?  —Preceding unsigned comment added by 82.92.195.174 (talk) 09:52, 14 April 2008 (UTC)

message: This article only focuses on pneumatic systems - it would be useful if someone would provide an overview of how "more electric" systems (such as that installed on the 787) differ.  — Preceding unsigned comment added by 132.244.72.5 (talk) 14:26, 3 June 2013 (UTC)

message: I came here from a link in Russia's current main battle tank article about its latest ECS for it.
This article should be expanded to included details about such solutions in other craft, namely ground war vehicles.  — Preceding unsigned comment added by 97.115.164.123 (talk) 07:19, 16 May 2014 (UTC)
