Flight path carrier maintained - aircraft restricting carbon chloride in essence (10)

Ross

I believe the answer is:

trajectory

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

'flight path' is the definition.
(I've seen this before)

'carrier maintained aircraft restricting carbon chloride in essence' is the wordplay.
I cannot quite see how this works, but
'carbon' could be 'c' (C is the chemical symbol for carbon) and 'c' is present in the answer.
'aircraft' could be 'jet' (jet is a kind of aircraft) and 'jet' is located in the remaining letters.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for trajectory that I've seen before include "Track of a projectile" , "Projectile's path" , "flight path" , "Path of an object through the air" , "Path of a bullet or missile" .)
