747-8I: "Pack Flow Econ Mode" and "HI Flow"

Recommended Posts

Hello Pilots! I´ve two questions so far: 

1. At the Equipment option page (FMC) there is an opton for enable the "Pack Flow Econ Mode". I found no description in the manuals about what this system does when enable this function.  Do you have an explantation? 

2. When do i activate "HI Flow" for the air-packs?

I found a description in the FCOM relatively fast, take a look at  Air Conditioning Packs system description starting on 2.20.1.

The supplementary procedures for air systems mention at least one case where high flow would be used on pg SP 2.2.

Oh man, sorry! I overread that... shame on me^^. What could be the benefit of choosing the "pack flow econ mode" for an airline?

As written, savings of 6% in flow when full normal flow is not required.  Money.
