Narrative:

I was arriving to ads from the northeast VFR under flight following and a discreet squawk. I received a dfw class B clearance several miles out before receiving vectors due to congested traffic. After the first vector from approach control for what would be an extended 'downwind' for ads; the controller issued the following statement: 'attention all aircraft that are going into addison; you can just assume at this point that you are cleared into bravo airspace.' while I had already received a bravo clearance; I found it unusual that a controller would issue a broad clearance not specific to a tail number. Shortly thereafter; and while vectoring me; the controller issued me a traffic alert for an aircraft at my 11:00 position; 2 miles and closing at my same altitude. He included an instruction for an immediate right turn to 220. It wasn't until I was established in my turn that I made visual contact with the traffic. I don't feel like there was an imminent collision potential; but given the controller's workload and the 'blanket' bravo clearance to other traffic; I felt it necessary to report simply for the sake of safety.

Title: General Aviation aircraft inbound to ADS reported confusion with the 'blanket Class B Clearance' issued by ATC to all aircraft inbound to ADS.

Narrative: I was arriving to ADS from the northeast VFR under flight following and a discreet squawk. I received a DFW Class B clearance several miles out before receiving vectors due to congested traffic. After the first vector from Approach Control for what would be an extended 'downwind' for ADS; the Controller issued the following statement: 'Attention all aircraft that are going into Addison; you can just assume at this point that you are cleared into Bravo Airspace.' While I had already received a Bravo clearance; I found it unusual that a Controller would issue a broad clearance not specific to a tail number. Shortly thereafter; and while vectoring me; the Controller issued me a traffic alert for an aircraft at my 11:00 position; 2 miles and closing at my same altitude. He included an instruction for an immediate right turn to 220. It wasn't until I was established in my turn that I made visual contact with the traffic. I don't feel like there was an imminent collision potential; but given the Controller's workload and the 'blanket' Bravo clearance to other traffic; I felt it necessary to report simply for the sake of safety.
