Half a pint for plenty of steersmen (6)
I believe the answer is:
'steersmen' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'half a pint for plenty' is the wordplay.
'half a' suggests halving the letters.
'for' is a charade indicator (letters next to each other).
'plenty' becomes 'lots' (I've seen this before).
'pint' cut in half is 'pi'.
'of' is the link.
Can you help me to learn more?
(Other definitions for pilots that I've seen before include "People who guide ships going into or out of a harbour", "They fly planes or guide ships", "Aircraft operators", "They fly aircraft and guide ships into harbour", "They are licensed to fly aircraft".)
