Narrative:
On takeoff runway 27R about 60 KTS #2 engine experienced a compressor stall which caused the autopack trip system to operate. We recognized the problem reinstated the air conditioning packs and we continued a normal takeoff. This condition happens occasionally and I would not normally report it in this manner, however the loud banging sound associated with a compressor stall was so loud, the controller in the tower heard the noise. He asked us on the radio if we were experiencing a problem and we told him we had a compressor stall, but all was fine. An aircraft lined up for takeoff also heard the noise and thought we had blown a tire telling us to keep our gear down however we knew what the problem was and continued a normal takeoff. This airline doesn't address compressor stalls as an abnormal.

Title: AN LGT ACR HAD A COMPRESSOR STALL ON TKOF THAT WAS LOUD ENOUGH TO ALARM ANOTHER ACFT AWAITING TKOF AND THE TWR CTLR.
Narrative: ON TKOF RWY 27R ABOUT 60 KTS #2 ENG EXPERIENCED A COMPRESSOR STALL WHICH CAUSED THE AUTOPACK TRIP SYS TO OPERATE. WE RECOGNIZED THE PROBLEM REINSTATED THE AIR CONDITIONING PACKS AND WE CONTINUED A NORMAL TKOF. THIS CONDITION HAPPENS OCCASIONALLY AND I WOULD NOT NORMALLY RPT IT IN THIS MANNER, HOWEVER THE LOUD BANGING SOUND ASSOCIATED WITH A COMPRESSOR STALL WAS SO LOUD, THE CTLR IN THE TWR HEARD THE NOISE. HE ASKED US ON THE RADIO IF WE WERE EXPERIENCING A PROBLEM AND WE TOLD HIM WE HAD A COMPRESSOR STALL, BUT ALL WAS FINE. AN ACFT LINED UP FOR TKOF ALSO HEARD THE NOISE AND THOUGHT WE HAD BLOWN A TIRE TELLING US TO KEEP OUR GEAR DOWN HOWEVER WE KNEW WHAT THE PROBLEM WAS AND CONTINUED A NORMAL TKOF. THIS AIRLINE DOESN'T ADDRESS COMPRESSOR STALLS AS AN ABNORMAL.
