Swissair manuals were ONLY in english.
Official cockpit language English only. (and for checks)
We weren't allowed to use anything but English on the RT - accept when the odd controller couldn't communicate efficiently in English.
There were the odd dubious procedures written by Swiss Germans in English - like a
prophylactic use of power - I hadn't come across the word before but an American friend told me it was a posh word for a French Letter!
As to french controllers although most speak excellent english I have recently heard two who didn't understand sufficient English.
Along a similar track an AF 380 pilot told me that the engineer who left the spacer out of the Paris Concorde only spoke French and the manual was in ....... English only!
