Dani,
Please do explain what a 'tailwind gust' is and how it would be detrimental to aircraft performance, specifically causing a tailstrike on takeoff.
Personally have been operating into ZRH since 1977 during all types of weather, and have never had any problems on takeoff...from any runway in use...16, 34, 28.
Those who are grasping at straws to explain the particular incident clearly are overlooking the primary reason tailstrikes occur on takeoff...over-rotation and incorrect V speeds selected for the actual takeoff weight.
Loadsheet error/incorrect loading...not very likely at all.
Windshear, possible but not very probable.
Crew error, THE primary factor in these all to common incidents.
Wonder just when crews and airlines will examine their particular procedures, especially how V speeds are determined (and carefully cross-checked with the proper printed charts), whether it is indeed proper to select the very utmost flex thrust for the particular takeoff, especially in cases where it is quite critical considering the MTOW, and more sim training so these incidents can be sharply curtailed.
Don't hold your breath.
The only likely scenario is if the hull insurance companies force airlines into this extra training, due to excessive payouts to fix the damage.
