Arrived, as a flight (6)
I believe the answer is:
landed
'arrived as a flight' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for landed that I've seen before include "Came ashore" , "Owning great estates" , "Set down, came to rest" , "With grounds" , "Arrived on shore or tarmac" .)
