Opening for The Aviator - broadcasts from March
I believe the answer is:
air space
'opening for the aviator' is the definition.
I can't tell whether this defines the answer.
'broadcasts from march' is the wordplay.
'broadcasts' becomes 'airs' ('air' can be a synonym of 'broadcast').
'from' says to put letters next to each other.
'march' becomes 'pace' (I can't justify this - if you can you should believe this answer much more).
'airs'+'pace'='AIR-SPACE'
Can you help me to learn more?
(Other definitions for air space that I've seen before include "A country's flying region" , "A country's flying zone" , "Atmosphere over (area of) earth" , "Through which planes are generally controlled" .)
