Delights confronting credit controller in aircraft (8)
I believe the answer is:
joystick
'controller in aircraft' is the definition.
(used to control an aircraft)
'delights confronting credit' is the wordplay.
'delights' becomes 'joys' (I've seen this in another clue).
'confronting' says to put letters next to each other.
'credit' becomes 'tick' (I've seen this before).
'joys'+'tick'='JOYSTICK'
(Other definitions for joystick that I've seen before include "Pilot's manual control" , "girl's to click" , "Manual computer game gadget" , "Aircraft's control lever" , "Flight control lever" .)
