I suspect the "high-altitude" refers to airport elevations in mountainous areas, and not cruising altitudes.

AFAIK, 9W had one or two of their aircraft retrofitted with this for operations to IXL.

I believe Airbus has installed a similar package on the A319s operating to Tibet.

Quoting OPNLguy (Reply 1):

That's a good guess. If the runway is more than 15,000 feet ASL, they'll want a special engine rating for takeoff, just for starters. All of the takeoff ratings I've seen stop at that altitude.

In addition to engine ratings, special provisions must be made for the cabin pressure controller and the cabin altitude warning/passenger oxygen system.

Instead of speculating, let's do something really unusual... like reading Boeing's page!

http://www.boeing.com/news/releases/2005/q2/nr_050624g.html

"The modifications include one hour of additional emergency oxygen supply and enhancements to the cabin pressure control system that allows operations at airports located at up to 14,500 feet. These airplanes can use the high-elevation airports in Western China such as Lhasa and Bangda."

The link above speaks of the delivery of an High Altitude Package.The modifications include one hour of additional emergency oxygen supply and enhancements to the cabin pressure control system that allows operations at airports located at up to 14,500 feet.

Shouldn't this be only a larger capacity O2 cylinder for crew & larger sized O2 generators for Pax.And a CPC upgrade.Or is there more to it.

They may also need special high speed tires and brakes, due to the high ground speeds at high altitidue airports.
