Narrative:
At dfw we have a waiver that allows departures to depart off both sides of the airport; at the same time; with less than standard separation. Recently working DR2 a heavy jet departed runway 18L and a regional jet departed runway 17R. The regional jet was less than a mi behind and to the left of the heavy. The regional jet was also at a lower altitude. This is a dangerous situation to put the pilot and passenger into; waiver or not.

Title: D10 CTLR EXPRESSES CONCERN REGARDING STANDARD WAKE TURB SEPARATION AND THE WAIVERED OPS UTILIZED AT DFW.
Narrative: AT DFW WE HAVE A WAIVER THAT ALLOWS DEPS TO DEPART OFF BOTH SIDES OF THE ARPT; AT THE SAME TIME; WITH LTSS. RECENTLY WORKING DR2 A HVY JET DEPARTED RWY 18L AND A REGIONAL JET DEPARTED RWY 17R. THE REGIONAL JET WAS LESS THAN A MI BEHIND AND TO THE L OF THE HVY. THE REGIONAL JET WAS ALSO AT A LOWER ALT. THIS IS A DANGEROUS SITUATION TO PUT THE PLT AND PAX INTO; WAIVER OR NOT.
