Narrative:
Cleared into position on runway 19R at sna. Another air carrier B757 had just landed. Traffic reporting on final runway 19R and 3-4 mi out, was a B737. Once the B757 started to clear runway 19R, the tower advised us cleared for takeoff. Power was advanced for a flaps 15 degrees, maximum power and bleeds off takeoff. Brakes were released and tower called to cancel our takeoff clearance. The B737 was told to go around. We had rolled maybe 2 to 3 aircraft lengths forward prior to stopping, and we taxied clear of taxiway K. Upon receiving a new takeoff clearance, we performed a 'normal' flaps 15 degrees, bleeds off noise abatement orange county takeoff! All carriers have to perform noise abatement takeoff procedures for runway 19R at orange county due to noise restrs. A congested ramp and an intermix of light and 'heavy' aircraft in such tight confines makes it very challenging for both pilots and controllers. Due to noise considerations and a relatively short runway, there are not many rolling takeoffs. Ample room must be allowed for aircraft to depart and advance advisory for aircraft on approach will give them time to slow (and additional space between departures and arrs). If not advised to slow, most carriers will use most fuel efficient procedures (go fast). Supplemental information from acn 334810: the controller did the right thing, but this situation was totally preventable. An inadvertent loss of a few seconds may have been the only thing that made a normal operation a critical one. All airliners need to stop before we can go, so power can be run up, and airliners on approach can only slow to final approach speed and no slower and unless instructed by tower to slow early. Also, an aircraft on landing rollout takes time to slow to turn off at a 90 degree taxiway.
Original NASA ASRS Text
Title: THE SNA ATCT LCL CTLR HAD TO CHANGE PLANS WHEN ACFT SPACING BECAME COMPROMISED. A B757 HAD JUST LANDED WHEN THIS FLC'S ACFT (B737) WAS CLRED INTO POS AND HOLD, AND THEN FOR TKOF. DURING THIS TIME A B737 FLC RPTED THAT THEY WERE ON A 3-4 MI FINAL. AFTER TAXIING INTO POS ON THE RWY, THE RPTING FLC HAD TO STOP THE ACFT BEFORE TKOF TO FOLLOW THE NOISE ABATEMENT PROC FOR ADDING TKOF PWR. SHORTLY AFTER THEIR BRAKE RELEASE, THE TWR CANCELED THE TKOF CLRNC AND SENT THE OTHER ACFT AROUND.
Narrative: CLRED INTO POS ON RWY 19R AT SNA. ANOTHER ACR B757 HAD JUST LANDED. TFC RPTING ON FINAL RWY 19R AND 3-4 MI OUT, WAS A B737. ONCE THE B757 STARTED TO CLR RWY 19R, THE TWR ADVISED US CLRED FOR TKOF. PWR WAS ADVANCED FOR A FLAPS 15 DEGS, MAX PWR AND BLEEDS OFF TKOF. BRAKES WERE RELEASED AND TWR CALLED TO CANCEL OUR TKOF CLRNC. THE B737 WAS TOLD TO GAR. WE HAD ROLLED MAYBE 2 TO 3 ACFT LENGTHS FORWARD PRIOR TO STOPPING, AND WE TAXIED CLR OF TXWY K. UPON RECEIVING A NEW TKOF CLRNC, WE PERFORMED A 'NORMAL' FLAPS 15 DEGS, BLEEDS OFF NOISE ABATEMENT ORANGE COUNTY TKOF! ALL CARRIERS HAVE TO PERFORM NOISE ABATEMENT TKOF PROCS FOR RWY 19R AT ORANGE COUNTY DUE TO NOISE RESTRS. A CONGESTED RAMP AND AN INTERMIX OF LIGHT AND 'HVY' ACFT IN SUCH TIGHT CONFINES MAKES IT VERY CHALLENGING FOR BOTH PLTS AND CTLRS. DUE TO NOISE CONSIDERATIONS AND A RELATIVELY SHORT RWY, THERE ARE NOT MANY ROLLING TKOFS. AMPLE ROOM MUST BE ALLOWED FOR ACFT TO DEPART AND ADVANCE ADVISORY FOR ACFT ON APCH WILL GIVE THEM TIME TO SLOW (AND ADDITIONAL SPACE BTWN DEPS AND ARRS). IF NOT ADVISED TO SLOW, MOST CARRIERS WILL USE MOST FUEL EFFICIENT PROCS (GO FAST). SUPPLEMENTAL INFO FROM ACN 334810: THE CTLR DID THE RIGHT THING, BUT THIS SIT WAS TOTALLY PREVENTABLE. AN INADVERTENT LOSS OF A FEW SECONDS MAY HAVE BEEN THE ONLY THING THAT MADE A NORMAL OP A CRITICAL ONE. ALL AIRLINERS NEED TO STOP BEFORE WE CAN GO, SO PWR CAN BE RUN UP, AND AIRLINERS ON APCH CAN ONLY SLOW TO FINAL APCH SPD AND NO SLOWER AND UNLESS INSTRUCTED BY TWR TO SLOW EARLY. ALSO, AN ACFT ON LNDG ROLLOUT TAKES TIME TO SLOW TO TURN OFF AT A 90 DEG TXWY.
