Synopsis
LAS Air Carrier departure from Runway 1R received a TCAS RA from traffic departing Runway 1L; traffic information was provided to both involved aircraft.
Narrative
Upon receipt of takeoff clearance on Runway 1R in LAS; tower advised that another aircraft would be cleared for takeoff from 1L but that it would be no factor. Shortly after takeoff at approximately 300 feet we received a resolution advisory; directing us to 'maintain vertical speed'. This was shortly after our power reduction; so to maintain the vertical speed we decreased our airspeed. I noticed that the aircraft to our left was co-altitude and very close on TCAS. Later; the flight attendant remarked that the aircraft on our left during takeoff was very close. The two runways are very close together at LAS; and it seems that two aircraft should not be allowed to take off at exactly the same time. There's very little margin for error. Also; most aircraft taking off on the left runway are smaller civilian aircraft. These pilots may not have very much experience. Any deviation from center line could be disastrous if both aircraft are cleared for takeoff at the same time. Also; our aircraft flight director takes off in runway track or NAV if on an RNAV SID; where others may take off initially with runway heading if not RNAV capable. If there's a left crosswind this would cause the aircraft taking off in heading from the left runway to veer into the path of the aircraft on the right runway. I've seen this problem before at LAS when taking off to the north; so this is an issue that needs to be addressed.
Second reporter narrative
On take off at about 1000 AGL we got an RA to monitor vertical speed. We complied with the RA. We were cleared for take off on 1R and the business jet was cleared to take off Runway 1L. I believe the RA was with that traffic. I believe the tower told us and biz jet about our respective traffic.
