Aircraft manufacturer, Dr Kee's manoeuvring guide (8)
I believe the answer is:
baedeker
'guide' is the definition.
(as in Baedeker travel guides)
'aircraft manufacturer dr kee's manoeuvring' is the wordplay.
'aircraft manufacturer' becomes 'BAE' (BAE Systems is an arms and aircraft company).
'manoeuvring' is an anagram indicator.
'dr'+'kee'='drkee'
'drkee' with letters rearranged gives 'deker'.
'bae'+'deker'='BAEDEKER'
(Other definitions for baedeker that I've seen before include "(German) travel guide" , "Travel guide author" , "publishing company" .)
