Narrative:

On may/xx/99, we operated flight abc from abq to stl. After completing all taxi and takeoff items and the appropriate checklist we were cleared for takeoff on the west runway in abq. Upon advancing the power levers the flap warning alarm came on instantly. The captain then brought the power levers back down and we taxied off the runway onto a taxiway. The engines never spooled up and the aircraft never went above taxi speed. The MD80 has a 'dial a flap' control which allows us to use many different flap settings. This particular flap setting was giving us an aural warning. We then called back to our operations and had them send us, via ACARS printer, a new set of takeoff performance figures for a new flap setting. After completing this and resetting the flaps, there was no warning, so we taxied back to the runway for takeoff. After completing all appropriate checklists again, and with no flap takeoff warning, we initiated a normal takeoff and proceeded to stl without incident. Supplemental information from acn 437223: we set the flaps to 4 degrees on taxi out using the automated takeoff chart data received from operations. On initiating takeoff, the 'flap' takeoff warning sounded. I taxied off the runway at taxiway A11, raised the flaps to the up position, reset the takeoff selector to 7 degrees and reset the flaps to 7 degrees. We then called ramp control and received takeoff data for a flaps 7 degree takeoff. I then confirmed that the flap takeoff warning would not sound with flaps 7 degrees, recompleted the taxi and before takeoff checklists, and made a normal takeoff on runway 26. It did not occur to me that there was anything wrong in these procedures, either from a legal or safety standpoint, and I am still of that belief. However, I have been informed that the FAA is investigating the situation so I am submitting this report.

Title: MD80 CREW ABORTED TKOF AFTER GETTING A TKOF WARNING HORN.

Narrative: ON MAY/XX/99, WE OPERATED FLT ABC FROM ABQ TO STL. AFTER COMPLETING ALL TAXI AND TKOF ITEMS AND THE APPROPRIATE CHKLIST WE WERE CLRED FOR TKOF ON THE W RWY IN ABQ. UPON ADVANCING THE PWR LEVERS THE FLAP WARNING ALARM CAME ON INSTANTLY. THE CAPT THEN BROUGHT THE PWR LEVERS BACK DOWN AND WE TAXIED OFF THE RWY ONTO A TXWY. THE ENGS NEVER SPOOLED UP AND THE ACFT NEVER WENT ABOVE TAXI SPD. THE MD80 HAS A 'DIAL A FLAP' CTL WHICH ALLOWS US TO USE MANY DIFFERENT FLAP SETTINGS. THIS PARTICULAR FLAP SETTING WAS GIVING US AN AURAL WARNING. WE THEN CALLED BACK TO OUR OPS AND HAD THEM SEND US, VIA ACARS PRINTER, A NEW SET OF TKOF PERFORMANCE FIGURES FOR A NEW FLAP SETTING. AFTER COMPLETING THIS AND RESETTING THE FLAPS, THERE WAS NO WARNING, SO WE TAXIED BACK TO THE RWY FOR TKOF. AFTER COMPLETING ALL APPROPRIATE CHKLISTS AGAIN, AND WITH NO FLAP TKOF WARNING, WE INITIATED A NORMAL TKOF AND PROCEEDED TO STL WITHOUT INCIDENT. SUPPLEMENTAL INFO FROM ACN 437223: WE SET THE FLAPS TO 4 DEGS ON TAXI OUT USING THE AUTOMATED TKOF CHART DATA RECEIVED FROM OPS. ON INITIATING TKOF, THE 'FLAP' TKOF WARNING SOUNDED. I TAXIED OFF THE RWY AT TXWY A11, RAISED THE FLAPS TO THE UP POS, RESET THE TKOF SELECTOR TO 7 DEGS AND RESET THE FLAPS TO 7 DEGS. WE THEN CALLED RAMP CTL AND RECEIVED TKOF DATA FOR A FLAPS 7 DEG TKOF. I THEN CONFIRMED THAT THE FLAP TKOF WARNING WOULD NOT SOUND WITH FLAPS 7 DEGS, RECOMPLETED THE TAXI AND BEFORE TKOF CHKLISTS, AND MADE A NORMAL TKOF ON RWY 26. IT DID NOT OCCUR TO ME THAT THERE WAS ANYTHING WRONG IN THESE PROCS, EITHER FROM A LEGAL OR SAFETY STANDPOINT, AND I AM STILL OF THAT BELIEF. HOWEVER, I HAVE BEEN INFORMED THAT THE FAA IS INVESTIGATING THE SIT SO I AM SUBMITTING THIS RPT.
