Black aircraft? (3)
I believe the answer is:
jet
I believe this clue is a double definition.
'black' is the first definition.
(similar in meaning)
'aircraft?' is the second definition.
(jet is a kind of aircraft)
(Other definitions for jet that I've seen before include "Plane - glossy black (stone) - stream" , "Narrow spouting stream" , "Glossy black colour" , "Very black or fast plane" , "Raven" .)
