Of your list, only these are acronyms:
NATS (little jets missing the "G")
AFPEX (a f------ poor excuse?)
SID (should've indicated decelerating?)
STAR (silly test about regulations?)
LARS (Swedish guy?)
LATCC (let all the chatter continue?)
SAM (surface to air missle?)
ACK (only half the anti aircraft fire?)
The rest are abbreviations,
