One who oversees meeting with Chinese pilot (8)
I believe the answer is:
chairman
'one who oversees meeting' is the definition.
(a chairman chairs a meeting)
'with chinese pilot' is the wordplay.
'with' means one lot of letters go next to another.
'chinese' becomes 'ch' (I've seen this in other clues).
'pilot' becomes 'airman' (someone who flies aircraft).
'ch' put next to 'airman' is 'CHAIRMAN'.
(Other definitions for chairman that I've seen before include "official in authority" , "He presides at a meeting" , "Casting voter" , "Presiding officer at meetings" , "president" .)
