Thank you for the reply..I'm very suprised though
So is it reliant on visual seperation between the 2 aircraft? What happens if the SID initially takes you away from the VFR traffic but then turns you into it.. Neither one of you can clearly see the other? Believe me flying a 100ft over a piper warrior is a little too close for comfort!!
I know TCAS may be able to offer an RA for the IFR traffic but it needs to be fitted in the first place.
