JAA stall warning requirements for turbofan aircraft?


Well-Known Member
Hopefully I am in the right post for this thread. If not I apologize in advance.
I am trying to find out if European registered turbofan aircraft must have an aural stall warning sign aside form the required master caution and shaker to be considered airworthy. And if yes, when did this requirement take place?
I have checked the JAR 25.207 that cover the stall warning requirements for certification. Checked the rest of the JARs but could not find anything.
I appreciate any help.
