Environment - Non Weather Related; Airport
During descent to airport after a mission; a TCAS Resolution Advisory (RA) was issued due to proximity to a regional jet which had just departed. We followed the RA. The two aircraft passed each other at a safe distance. Without TCAS; this would have been a near miss at best.The wind was favoring; and all aircraft had been using; Runway XX all day. The CRJ took off the opposite direction because the winds were variable at 4. We were planning Runway XX on our initial descent and were prepared for the straight in Runway XX approach we had received previously. [This airport] does not have radar or an ATIS so we had no knowledge of the departing traffic until we checked on at 12 miles out.Based on the conversation I overheard between tower and the CRJ; it was clear that the CRJ did not know that there was no radar coverage in the area. They were much more concerned with talking to the tower about traffic they saw on their TCAS than maneuvering to avoid it. They also were unaware that other high speed traffic may be transiting the uncontrolled airspace without communicating to ATC. Vigilance outside the cockpit must be maintained. Pilots are way too distracted inside these days; and are not using a proper 'see and avoid' technique. Fortunately the TCAS equipment worked well.
BAE146 pilot on approach reported an airborne conflict with a CRJ200 departing from the opposite direction. The TCAS RA was complied with to maintain separation.
