Hi DownIn3Green,
It leads you to an article in the AvHerald, quoting the ACTUAL REPORT.....In other words, journalist license...
The link is incorrect - it should say: (in BFU's language)
http://www.bfu-web.de/EN/Publication...ublicationFile
On seite 46 "During the next few seconds the aircraft rolled to a 23° left wing down attitude in spite of the full right deflection of both sidesticks and application of right rudder."
On seite 47 "Within this investigation the wind conditions derived by simulation and calculation were used as additional factual information. This enabled the BFU to work on the assumption that the actual crosswind component was about 30 kt gusting up to 40 kt."
On seite 35 "The following values were documented in the manufacturer's FCOM for Airbus A319/A320/A321 in the
chapter OPERATING LIMITATIONS (Appendix 6):
• Wind for takeoff and landing:
• Maximum crosswind demonstrated for takeoff: 29 knots gusting up to 38 knots
• Maximum crosswind demonstrated for landing: 33 knots gusting up to 38 knots"

The crew had no idea that they were about to run out of aileron authority when (seite 63) "The aircraft was designed so that the effect of lateral controls (along the longitudinal axis) would reduce by about one half of full deflection as soon as one main landing gear touched down."


Old Smokey sums up nicely Airbus documentation in post 6 of http://www.pprune.org/tech-log/51505...-question.html
