Whoa Brother!!! Abort!abort! set TOGA!! 
Hi. It's great seeing how you and many others are takin a serious
interest in the aviation industry as a career and not play play and
wanna get near the stewadesses. i have people wanting to "join"
aviation industry so as to get near the "kebayas"..and i absolutely
deplore this kind fo attitude.
First of all, you have to know what you want to do in the aviation
industry .Your IT experience is a valuable asset since airlines are
using state of the art techno and IT ple play a significant role. I
hav IT people fro outside who got a contract to help our route
planning computers are it is so dificult sicne they hav no idea wat
our parameteres are so I hav to spend 1 week of induction and
training for them and once they understand, it's all systems
go!
BUt then again, it's difficult for you to know exactly what u wan
to do since it is such a small and new field .esp for us here. U
say u wana get to do routeplanning and in obtaining o/flyng and
landing rights.that is a very advance part of job and only seniors
can do that ..u need not just good technical skills but
experience.
Briefing, to do routeplanning, you need to hold a dispatcher's
license, u need to hold training in performance, navigation and
charting, knowing how to read Jeppesen charts, airport analysis,
RNWy analysis, RFF caterogry suitable for ur kind of aircraft ,
route manual studies, pre-diligence studies,ETOPS ? and then there
is that corporate side of demands.
1.Please..u can;t hop on to an airline industry becoz u hav
experience in planning SBS transit..it's a diff ball game. Pilots
are governed by FTL, basing on thier AOC either 9V or JAROPS, SBS
captains don;t. (though I hope they do ).
2.Joing as an enginner, assuming it's aircraft engineer will still
put you ZERO in routeing planning or flight operations. It is a
dedicated job and by the time u finished training and ur bond, you
might not want to go flght or ground opeartions.
3. Perhaps u might like to consider joingin the ATC. but rememer
the test is tough, Bond is arnd 6 years and not unionised. Job is
challengin but there are no more rotation between tower controllers
and area,approach in SATCC. (like last time)
4. h/ever with SATS flight ops, BOND is one year and u get good
training.
it's too long to list down but it an encouraing trend that peple
are taking a more "indepth" look into aviation.
Many times pple got misguided thinking that tower belongs to
SIA.
Drop me a line if u hav more queries.
Till then, HAPPY FLYING....
