Narrative:

While performing the noise abatement sna departure; at 3;000 feet MSL; per fom; we began to clean up the aircraft and accelerate. As the pilot monitoring; I responded to socal on initial contact and confirmed we were cleared to 5;000 feet MSL. While the autopilot engaged; the pilot flying (captain) flew the departure as per company fom. At approximately 3;500 feet - 4;000 feet MSL; socal called traffic left eleven o'clock; five miles at 6;000 feet MSL converging on our position. Socal was in contact with the traffic (pilatus pc-12); as we heard their radio conversation. At approximately 4;100 feet MSL; our aircraft generated a TCAS RA. The pilot flying disengaged the autopilot and followed RA guidance. As pilot monitoring; I radioed socal and informed them we were reacting to a TCAS RA. Socal acknowledged our radio call; and then directed us to contact la center on the prescribed frequency. At no time did socal indicate there was any question regarding our proper reaction to the TCAS RA.

Title: Air carrier departure from SNA; on the noise abatement rapid climb; experienced a TCAS RA with traffic assigned above with minimal IFR separation.

Narrative: While performing the noise abatement SNA departure; at 3;000 feet MSL; per FOM; we began to clean up the aircraft and accelerate. As the Pilot Monitoring; I responded to SoCal on initial contact and confirmed we were cleared to 5;000 feet MSL. While the autopilot engaged; the Pilot Flying (Captain) flew the departure as per company FOM. At approximately 3;500 feet - 4;000 feet MSL; SoCal called traffic left eleven o'clock; five miles at 6;000 feet MSL converging on our position. SoCal was in contact with the traffic (Pilatus PC-12); as we heard their radio conversation. At approximately 4;100 feet MSL; our aircraft generated a TCAS RA. The Pilot Flying disengaged the autopilot and followed RA guidance. As Pilot Monitoring; I radioed SoCal and informed them we were reacting to a TCAS RA. SoCal acknowledged our radio call; and then directed us to contact LA Center on the prescribed frequency. At no time did SoCal indicate there was any question regarding our proper reaction to the TCAS RA.
