Confused, so I omit catapult or devices keeping aircraft on course (9,6)

I believe the answer is:

automatic pilots

I'm a little stuck... Click here to teach me more about this clue!

'devices keeping aircraft on course' is the definition.
I can't judge whether this definition defines the answer.

'confused so i omit catapult' is the wordplay.
'confused' indicates anagramming the letters.
'so'+'i'+'omit'+'catapult'='soiomitcatapult'
'soiomitcatapult' with letters rearranged gives 'AUTOMATIC PILOTS'.

'or' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
