If you are IFR they already know you are coming. Doesn't SYD arrivals hand you off to the tower anyway?
Yes they do - tower gets an estimate for IFR arrivals, but the NOTAM makes no distinction to flight category. IFR or VFR, arriving from Class G or Class C, all aircraft must CTC TWR 2 mins prior with an estimate for the APP point.
What will happen if I turn up at 2RN or PSP and didnt give an estimate 2 mins ago? Will an incident report be put in on me?
Maybe I didnt get in my estimate because the frequency was too congested with people trying to figure out where other people are...
'..estimating PSP 2 mins'
'...Im also 2 mins from PSP, I dont see you. Im a metro, 10 miles out'
'...Im an R22, 2 miles out'
'...Im to the north west'
'...Im to the south'
Its happening already
