'agitated' is the definition.
Although both the answer and definition are past participle verbs, I can't understand how one could define the other.

'operated aloft' is the wordplay.
'operated' becomes 'worked' ('work' can be a synonym of 'operate').
'aloft' becomes 'up' (up above).
'worked'+'up'='WORKED UP'

'having' is the link.

Can you help me to learn more?

(Another definition for worked up that I've seen is " In a tizzy".)
