Being French, I go to central Austria by plane (3)
I believe the answer is:
jet
'plane' is the definition.
(jet plane)
'being french i go to central austria by' is the wordplay.
'being french i go' becomes 'je' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to central' means to look at the middle letters.
'by' is a charade indicator (letters next to each other).
The central letter of 'austria' is 't'.
'je'+'t'='JET'
Can you help me to learn more?
(Other definitions for jet that I've seen before include "A spring in ballet" , "Raven" , "Hard black mineral used as gem" , "Black variety of lignite, used for ornaments" , "Spurt; aircraft" .)
