Squawking in the circuit
Hello,
I have just been involved in a discussion with a fellow PPL'er about what to squawk in the circuit, with me been someone who squawks standby (although today was C with a squawk due to I believe the primary radar been U/S) and him someone who squawks C7000.
The reasoning behind his decision to squawk C in the circuit was so that any TCAS equipped aircraft could see him. However I argued that this could possibly be a problem at a larger airfield that if you flew a tight circuit and set off a TA/RA the TCAS aircraft would have to execute the resolution (and create an unhappy crew) even though we were clearly in sight and avoiding.
Therefore my question is - is there a correct procedure on what to squawk in the circuit?
Thanks
