A320 pack flow LO when pax >115
Wanted to find out something from the A320 Guru’s!!
Our company just came out with a policy to keep the pack flow to low regardless of number of pax travelling. Usually our flights are full (180 pax).
I understand that at LO setting it is 80% of normal and if the temperature demand cannot be met it reverts back to Normal (100%). But there is no mention of quality of air, what if the temperature demand can be met, is 80% flow is adequate for 180 pax? There has to be a good logical reason why A320 FCTM says to use pack flow to LO when pax load is less than 115.
Any comments?
