Narrative:

It was a beautiful day in narita -- just a few clouds in the sky, winds stable at about 10 KTS within 30 degrees of runway heading, visibility virtually unrestr -- and it was my leg from tpe to nrt, so I elected to do an autoland for the practice. The aircraft performed beautifully on the approach, and all indications were normal. We got all 3 landing tones on schedule, and the aircraft started its gentle flare at just the right time. At this point, however, instead of holding that flare pitch attitude, the aircraft kept increasing pitch steadily! Since I was guarding the controls, I instinctively tried easing the yoke forward for a split second -- at this point the captain looked over at me and saw my actions, and at that point, knew that something was awry. Also, simultaneously, the aircraft began 'flying' and we found ourselves with a nose high attitude, decreasing airspeed, at about 30 ft. We both simultaneously went full power, and a normal go around and manual landing was made. Notes: 2 or 3 aircraft were in line for departure on runway 34, one of which was 90 degrees to the runway at the hold line. Previous day's write-up had 'no land 3' signed off. Also, on takeoff from tpe that morning (same leg), autothrottles didn't engage until approximately 400 ft. Personal observations: 1) perfect day and perfect approach. You might not be as ready for anything, as in bad WX. Watch that complacency! 2) those notes and circulars put out about not having aircraft in the protected ILS/localizer zones during coupled approachs might be right! 3) always correlate (as best you can) previous write-ups and current anomalies for patterns. It may pay off!

Title: UNUSUAL FLARE DURING AUTOLAND.

Narrative: IT WAS A BEAUTIFUL DAY IN NARITA -- JUST A FEW CLOUDS IN THE SKY, WINDS STABLE AT ABOUT 10 KTS WITHIN 30 DEGS OF RWY HDG, VISIBILITY VIRTUALLY UNRESTR -- AND IT WAS MY LEG FROM TPE TO NRT, SO I ELECTED TO DO AN AUTOLAND FOR THE PRACTICE. THE ACFT PERFORMED BEAUTIFULLY ON THE APCH, AND ALL INDICATIONS WERE NORMAL. WE GOT ALL 3 LNDG TONES ON SCHEDULE, AND THE ACFT STARTED ITS GENTLE FLARE AT JUST THE RIGHT TIME. AT THIS POINT, HOWEVER, INSTEAD OF HOLDING THAT FLARE PITCH ATTITUDE, THE ACFT KEPT INCREASING PITCH STEADILY! SINCE I WAS GUARDING THE CTLS, I INSTINCTIVELY TRIED EASING THE YOKE FORWARD FOR A SPLIT SECOND -- AT THIS POINT THE CAPT LOOKED OVER AT ME AND SAW MY ACTIONS, AND AT THAT POINT, KNEW THAT SOMETHING WAS AWRY. ALSO, SIMULTANEOUSLY, THE ACFT BEGAN 'FLYING' AND WE FOUND OURSELVES WITH A NOSE HIGH ATTITUDE, DECREASING AIRSPD, AT ABOUT 30 FT. WE BOTH SIMULTANEOUSLY WENT FULL PWR, AND A NORMAL GAR AND MANUAL LNDG WAS MADE. NOTES: 2 OR 3 ACFT WERE IN LINE FOR DEP ON RWY 34, ONE OF WHICH WAS 90 DEGS TO THE RWY AT THE HOLD LINE. PREVIOUS DAY'S WRITE-UP HAD 'NO LAND 3' SIGNED OFF. ALSO, ON TKOF FROM TPE THAT MORNING (SAME LEG), AUTOTHROTTLES DIDN'T ENGAGE UNTIL APPROX 400 FT. PERSONAL OBSERVATIONS: 1) PERFECT DAY AND PERFECT APCH. YOU MIGHT NOT BE AS READY FOR ANYTHING, AS IN BAD WX. WATCH THAT COMPLACENCY! 2) THOSE NOTES AND CIRCULARS PUT OUT ABOUT NOT HAVING ACFT IN THE PROTECTED ILS/LOC ZONES DURING COUPLED APCHS MIGHT BE RIGHT! 3) ALWAYS CORRELATE (AS BEST YOU CAN) PREVIOUS WRITE-UPS AND CURRENT ANOMALIES FOR PATTERNS. IT MAY PAY OFF!
