He sails misguided airmen to Central America (7)
I believe the answer is:
mariner
'he sails' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'misguided airmen to central america' is the wordplay.
'misguided' is an anagram indicator (I've seen this in other clues).
'to central' indicates the central letters.
The central letter of 'america' is 'r'.
'airmen' anagrammed gives 'marine'.
'marine'+'r'='MARINER'
Can you help me to learn more?
(Other definitions for mariner that I've seen before include "Seaman" , "'''The Rime of the Ancient ...'' (Coleridge) (7)'" , "See 13" , "Jack" , "Sea-goer, ancient in the poem" .)
