Thanks again, mjbow2. My source suggests that there are not many RAs received daily over there, at least not ones that are, for want of a better word, ‘unexpected’. My source suggests that at some airports where there are simultaneous opposite direction approaches to base of parallel runways, and an RA is entirely expected and normal part of the approach, given the heavy metal coming the other way and descending towards (but hopefully not to!) exactly the same point in space.
As to RAs of the kind recently investigated by the ATSB – my source can’t recall having had one.
Can any heavy metal drivers out there tell us about their RA experiences in US E?
