This is better than fun!!!
Thanks so far but let me run a scenario past you all
A/C departs on a local flight and when asked
FLIGHT RULES replies IFR, when asked Service required replies RIS which is given.
In the way is an IFR transit that is also on a RIS.
Traffic info given at appropriate time but due workload a/c come within 2nm and 700ft. Transit a/c not happy" I am IFR" etc so says he will file.
At the subsequent board of enquiry how much sh1t comes the ATCO's way
