Narrative:

On taxi out of msp the bleed air light on the so's panel annunciated. This is an APU flow multiplier overheat. This is not uncommon given the conditions of the day (hot ambient temperature and full passenger load). The problem was corrected with the proper checklist by turning off the #2 bleeds (which is the normal confign for this phase of flight). The captain did not believe this to be a problem as the cause may have been aggravated by the so leaving the #2 bleeds open, after engine start, with the air conditioning packs on. Normally after engine start, the #2 bleeds are closed and air conditioning packs are run off engine bleeds, #1 and #3. The so wrote up the discrepancy as having 'bleed air light tripped on taxi out of msp and taxi in to atl. We should have contacted dispatch prior to departing msp.

Narrative: ON TAXI OUT OF MSP THE BLEED AIR LIGHT ON THE SO'S PANEL ANNUNCIATED. THIS IS AN APU FLOW MULTIPLIER OVERHEAT. THIS IS NOT UNCOMMON GIVEN THE CONDITIONS OF THE DAY (HOT AMBIENT TEMP AND FULL PAX LOAD). THE PROB WAS CORRECTED WITH THE PROPER CHKLIST BY TURNING OFF THE #2 BLEEDS (WHICH IS THE NORMAL CONFIGN FOR THIS PHASE OF FLT). THE CAPT DID NOT BELIEVE THIS TO BE A PROB AS THE CAUSE MAY HAVE BEEN AGGRAVATED BY THE SO LEAVING THE #2 BLEEDS OPEN, AFTER ENG START, WITH THE AIR CONDITIONING PACKS ON. NORMALLY AFTER ENG START, THE #2 BLEEDS ARE CLOSED AND AIR CONDITIONING PACKS ARE RUN OFF ENG BLEEDS, #1 AND #3.
