High-fliers must have raw rice boiled (7)
I believe the answer is:
aircrew
'high-fliers must' is the definition.
I can't judge whether this defines the answer.
'raw rice boiled' is the wordplay.
'boiled' is an anagram indicator (letters cooked or boiled into a new form).
'raw'+'rice'='rawrice'
'rawrice' with letters rearranged gives 'AIRCREW'.
'have' is the link.
Can you help me to learn more?
(Other definitions for aircrew that I've seen before include "Pilots, stewards, etc" , "Regular high fliers" , "Plane's staff" , "flyers" , "Plane's operators" .)
