Where can i find the preflight checks in those massive manuals to taxi. I am getting an Air Condition warning when passing 10,000 feet. i am just following some tutorials out there waiting for AOA to start their flight sections.

Afraj, Just so you know, you posted this topic three times in a matter of minutes. Please be careful in the future to not post a topic more than once. Thank you.

I think you need to set the cruise altitude and make sure the engine bleeds are turned on. I've had that happen a few times after takeoff too.

The checklists can be found in the Quick Reference Handbook. Alternatively the procedures which accompany the checklists are in FCOM vol 1 starting around page 79.As for the air con alarm above 10000, you have probably not turned the packs on again after starting the engines.

Refer to FCOM Volume 1 Normal Procedures Section 21 - Amplified Procedures
