Narrative:

Aircraft X departed runway 18L on the RNAV and aircraft Y was my departure off of runway 18C. Aircraft X turned right instead of staying south toward my departing aircraft Y. The departure controller noticed aircraft X turning and immediately turned him southeast to avoid a possible collision. I have several recommendations to fix this. 1. This one is my fault I should have waited until I observed the turn before I switched my aircraft I admit the. Now due to the complexity of the adw window I was focused on the 23 final waiting to launch my next aircraft. We need to have local control east hold on to their departures. Now that I have worked this operation which I feel will directly result in an aircraft accident one day; it seems like the local control east is doing less and should hold on to the departures to provide visual with my aircrafts. Local control center has too much going on to worry about an aircraft turning almost five miles away from the airport.2. We need to revisit noise abatement here at clt and figure out a way to turn our departures off the deck away from each other. This is my second facility with simultaneous departures and the same problems happen here just like my old facility. A 210 heading off of [runway] 18C is enough to turn away from the [runway] 18L departures and still not be in the way of a [runway] 18R or [runway] 23 go-around;. A 150 heading with all east departures will help reduce the odds of an aircraft turning right. If they are a southbound aircraft RNAV is fine because at least the [runway] 18C departures are turning west. 3. I believe we need to stop issuing RNAV to the fix from local control. I believe this makes the odds go up [with] the controller saying the wrong RNAV fix or the pilot hearing the RNAV fix. We quit using it at my old facility after 6 months or so and the transition was very smooth and safe.
