Thanks for replies,
As a non-native English user, a word "tranasparent" imples me,
"things going on are easily noticable by pilot".
However, when I perceive this translation in the following texts (extracted from A 330 manual) they becomes obviously incorrect.
IN FLIGHT: the system updates the predictions and the current econ speed, using the
measured wind at present position. It mixes actual wind and forecast winds to compute
the wind ahead of the aircraft but this is totally transparent to the crew
or
If the uplink message contains more data and waypoints than the flight plan, the winds
at extra waypoints are not considered and are automatically discarded. This is
transparent to the flight crew.
Briefly, I understand that, I should comment the word
transparent in the texts of Airbus different than (in fact
opposite than) daily usage of this word as Lomapaseo, Wiggy and Chk Airman has explained.
I would be suggesting Airbus could be using a clearer wording in their Operation Manuals.
Thanks again
