Tail wind... on B737-900
Hi everyone,
Hope that the right forum for this question.
Since I started to learn how to fly, I learned that the max tail wind speed is 10 kt.
Today, flying the B737-900, I was said the aicraft can be landed or took of with a 15 kt max tail wind.
1) it is definitely in the limitation chapter of the FCOM.
2) it is also in the AFM (section 1, page 4) but, I would like to re-transcript word by word what it is written:
------------------------------------
Maximum Takeoff and landing Tailwind component -- 15 knots
NOTE:
The capability of this airplane has been satisfactorily demonstrated for takeoff and manual landing with tailwinds up to 15 knots. This finding does not constitute operational approval to conduct takeoffs or landings with tailwind components greater than 10 knots.
-------------------------------------
Can someone explain to me the meaning of the last NOTE sentence. It seems to me highly contradictory with the limitation in the FCOM and the above first line in the AFM. What I understand is that the aircraft has been tested up to 15 knots, but it is operationally approved for 10... ONLY!
I am wrong or is it my english understanding level?
Thanks in advance for your comments.
