Squawk

[Sonia767]

Hello............:O

I was wondering lets say you were given a squawk by atc for example 1243.

Then somewhere along the way you had a comm. problem.Would u squawk 7600 or 7643 ie would you retain the last two numerals from your squawk.

Just wondering ;) ;)

Thanks,

Sonia

7600. Any other 76xx code is a 'normal' (ORCAM) code.

Change to 7600. The fancy electronic devices that we have attatched to our RADAR in the back waters of SA will correlate the track with the code you had on previously and when the label on the screen lights up light a christmas tree it will usually keep the flight data from the previous ssr code and transfer the info

code ususally

SAA ***
FL GS
INFO

So in the info tine if you sqwak 7600 it will read RCF and normally keep the callsign info in place provided the change from 12345 to 7600 is made within +/- 10 sec if not then it will show 7600 instaed of the callsign and the ATC can re-initiate the call sign once he figures out who it is that has the problem

We use a old system so the ones in more modern states should do the same.:O :O

Little One is correct, same in UK, the previous flight data is retained whilst your 'blip' flashes away merrily to alert the control staff.
