Follows fix for flier's spiral descent (8)
I believe the answer is:
tailspin
'flier's spiral descent' is the definition.
I can't tell whether this defines the answer.
'follows fix' is the wordplay.
'follows' becomes 'tails' (I've seen this in another clue).
'fix' becomes 'pin' (to pin is to fix in place).
'tails'+'pin'='TAILSPIN'
'for' is the link.
Can you help me to learn more?
(Other definitions for tailspin that I've seen before include "Spiral aeroplane dive" , "awful state" , "State of rapidly increasing panic" , "Chaotic situation" , "Alpinist (anag) -- state of panic" .)
