Where i work (regional airport similar size to BRS) we neither pass the elevation (except for an SRA) by RT or on the atis, and I have never been asked for it.
Personally I think passsing it to a commercial aircraft is tantamount to telling em the final approach track or ILS frequency??? Correct me if I'm wrong here pilots, but arent most of you landing ref the rad alt these days anyway, and pressumeably its a requirement to have the appropraite plate in front of you anyway which has all that info on it. And even the aircraft that dont have rad alts have still never asked me for the elevation.
I'm not having a pop at anyone who does it(and certainly dont want this to degenerate into another Bristol slagging exercise), as lots of places ive flown to do pass the elev, my point is that if we dont pass it, and no one has every complained or said we should...is it really necessary???
