ATC Issue All Types; Inflight Event / Encounter Wake Vortex Encounter
General None Reported / Taken
Procedure; Environment - Non Weather Related
On departure out of ATL; we encountered moderate wake from an A321. Autopilot remained engaged during the encounter. We had requested additional time for increased separation between us and the preceding aircraft prior to departure; which was granted. Departing behind an A321; despite leaving increased room for separation for anticipated wake turbulence. ATL Tower has increased the rate at which they launch aircraft; regardless of the size. While it would slightly slow the rate at which aircraft are able to depart ATL; giving more room between departing aircraft of such disparate size (CRJ behind an A321 for example) will decrease these types of adverse wake encounters. Had we not asked for the additional time; it was likely that Tower would've cleared us to depart prior to the A321 rotating off the runway. That type of lack of separation significantly increases the chances of a severe wake encounter extremely close to the ground.
Reporter stated hopefully ATL in-trail procedures will be adjusted to minimize risk.
CRJ First Officer reported encountering wake turbulence departing ATL in trail of an A321; and questioned current ATL spacing procedures.
