Gets close to the ground and brings plane down in relatively flat area (8)
I believe the answer is:
lowlands
'area' is the definition.
(I have seen 'Area of Scotland ' mean 'lowlands' so perhaps 'area' could also mean 'lowlands')
'gets close to the ground and brings plane down in relatively flat' is the wordplay.
I cannot quite understand how this works, but
'gets' could be 'lands' (landing is a kind of getting) and 'lands' is found in the answer.
'down' could be 'low' (similar in meaning) and 'low' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lowlands that I've seen before include "Southern part of Scotland, not mountainous" , "Owls land (anag.)" , "Natural depressions" , "Areas that are not mountainous, in Scotland, say" , "Area of Scotland" .)
