He's always paying flying visits (5)

I believe the answer is:
pilot
'he's always paying flying visits' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for pilot that I've seen before include "Name of Mr Rochester's dog" , "Steer, test (scheme)" , "Plane flier" , "Person in charge of aircraft" , "who shows the way?" .)
