Aren't we forgetting traffic separation ? When VFR in a control zone here in Denmark (and I guess elsewhere) all you get is traffic information !
As a pax I wouldn't feel comfortable in the back of a 737 with the PF using half of her mental energy trying to spot and avoid two or five C172s in the pattern.
As a private pilot, I am sometimes busy enough trying to spot AC that the TWR has informed me of.
Or am I missing something ?
