June 25, 201015 yr Hi allIn the last 2 takeoffs, I have noticed that a level 0 alert is displayed on the EAD showing BLEEDS ALL OFF and dissapears when engaging AUTOFLIGHT. I haven`t noticed about that before, so in the case that this alert appears every time, would be normal, right?Looking at the QRH, it tells, All three bleeds have been turned off for a bleeds off takeoff. Problably this alert will be of no consecuence, but just to ensure.Thanks Asier Asier Azpiazu

June 25, 201015 yr Author Thanks Rob for your fast reply. I assume this alert will be displayed in every takeoff unless you select PACKS ON in the MCDU.Asier Asier Azpiazu
