Traditional manufacturer needs entitlement to be heard (6)
I believe the answer is:
wright
'traditional manufacturer' is the definition.
(shipwright, wheelwright, cartwright etc)
'entitlement to be heard' is the wordplay.
'entitlement' becomes 'right' (I've seen this before).
'to be heard' indicates a 'sounds like' (homophone) clue.
'right' sounds like 'WRIGHT'.
'needs' is the link.
(Other definitions for wright that I've seen before include "One of the first to stay up" , "One makes things, plays say" , "The ...... brothers pioneered aeroplane flight" , "Frank Lloyd ... (aviator)" , "Aviation pioneers' name" .)
