Feel disposed to take flight (4)
I believe the answer is:
flee
'take flight' is the definition.
('flee' can be a synonym of 'take flight')
'feel disposed' is the wordplay.
'disposed' is an anagram indicator.
'feel' anagrammed gives 'FLEE'.
'to' acts as a link.
(Other definitions for flee that I've seen before include "Run quickly away" , "Run (from danger)" , "Take flight" , "Take to one's heels" , "rush" .)
