Start for dynamic or nautical (4)

Ross

I believe the answer is:

aero

'start for dynamic or nautical' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for aero that I've seen before include "Prefix meaning air or aircraft" , "bar" , "Prefix denoting air" .)

I've seen this clue in The Wall Street Journal.
