A golf club pilot? (6)
I believe the answer is:
driver
I believe this clue is a double definition.
'a golf club' is the first definition.
(I know that Driver is a type of Wood)
'pilot?' is the second definition.
(I know that driver is a type of vehicle operator)
(Other definitions for driver that I've seen before include "Golf club for long shots" , "Operator of a motor vehicle" , "chauffeuse" , "Golf club; chauffeur" , "Type of golf club" .)
