A plane links projected landings (7)

I believe the answer is:

jetties

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

'landings' is the definition.
(I know this)

'a plane links' is the wordplay.
'a plane' becomes 'jet' (jet plane).
'links' becomes 'ties' (tie can mean a connection or link).
'jet'+'ties'='JETTIES'

'projected' is the link.
This may not be right. It may belong to another bit of the clue.

Can you help me to learn more?

(Another definition for jetties that I've seen is " Piers".)

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