Wind Check on final
Hello all,
Let's say your MAX TAIL WIND LIMIT IS 15Kts. (B777), at 500ft, you request wind check and tower reports 14Kts, you can officially land, as the only official wind is the tower reported wind.
But, your FMC PROGRESS 2/4, reads a tail wind above 15Kts, you continue, and land. This time, you have been unlucky and skidded off the RWY.
How would you be judged by your company?
The bellow was extracted from an overrun incident investigation:
FDR data was found to indicate that "the average tail wind component during the 15 seconds prior to initial touchdown was 12.95 knots" - in excess of the AFM maximum 10 knot tailwind component for landing. It was noted the same information was available on the MFD, but that Operator SOP for landing and takeoff limitation purposes, was to rely on wind velocity communicated on ATIS or direct from ATC.
The crew followed the SOP but was unfortunate.
Question:1. Does your company recommend or suggests any other wind information for landing that is not the REPORTED TOWER WIND?
2. Do you base your land/go-around decision on the FMC wind information?
Happy flights!
