You cannot abbreviate it yourself.
Only Ground station will initiate/do so and you can follow it till end of trasnmission, and return to original.
Three types:

ABBR: Golf - Golf Sierra
2)RT Operators designator + ICAO’s registratin marks
Full: OXBOW DCBA
ABBR: OXBOW Bravo Alpha
3)RT Operators designator + Flight number
Full: OXBOW 246
ABBR:NONE
How does an Aircraft initiate comms with Ground station
1)Ground station name + service
2)Aircraft call sign
3)Request/message
ex:
Stanstead Tower,
Golf - Alpha Bravo Charlie Delta, Request joining instructions
Continuing transmission
(with regards to call signs)
a) Ground station will always put AC callsign first
“G-CD, Line up, Runway 20’
b)Aircraft will put its call sign at the end of the repeated/acknowledged instruction
Lining up, Runway 20, G-CD
exception:
if minutes elapse between receiving instructions from Ground Station…then aircraft will begin with its call sign (to refresh)
G-CD, lining up, Runway 20
Say again..
if there is doubt that a message has been received correction, you may be asked to repeat the request…
ex:
AC:
G-CD, right base to land, Runway 20
GS
G-CD, Say again
AC
G-CD, right base to land, Runway 20
say again your call sign…
if identity of the calling station (ie Aircraft calling sign):
AC:
stanstead tower, Golf Alpha bravo Charlie Delta, Request flight information service
GS:
Station calling statstead tower, **say again your call sign **
Ac:

When under the control of ATCU
AC cannot swap from one ATCU to another without premission of currect ATCU in transmission.
