Hi Koen, I meant how do I know "as a pilot" when to turn them off or leave them on? is there a chart or indication for that?

There is no chart or indication for it. I usually run 1 pack on the ground and turn that one off when reaching the holding point if i was doing a pack less takeoff. This keeps passenger comfort at a good level. If i was doing a a take off with packs i leave both on when on the ground.

certainly in summer in hot destinations and short runway. Having both packs on at high till i reach the holding point as it helps comfort.

for places like Innsbruck i keep the packs on but i use the apu bleed to drive the packs instead. This will cause the engines to still have the same power.

To add to what Koen says.

Its also airline SOP, e.g BA like packs OFF for take off, another airline like USA ones like packs ON. There is no right/wrong. Its down to weather temp etc and Airline SOP.
