You're welcome - thanks very much for bringing it up, so we have at least a slim chance of correcting this situation.

Yes, and in the near term, I suppose we should take comfort that CAP training of Mission Scanners for postural ground-air signals is correct.

I guess that, interim, "X" might be our best choice for a linear ground-air signal.

Long term, the CAP Mission Scanning training should be fixed. The Mission Scanners need to understand what the survivors are saying, and
the five linear distress signals are what the FAA [1], USAF[2], National SAR manual, ICAO and IMO are telling the survivors to use. References [1] and [2] are from 2017, so should be up to date.

While the March 2017 US Army manual[3] for US army military ground-air coordination omits "V" and uses the old meaning of "X", the latest US Army survival manual (FM 21-76) I found told US Army survivors to use the five international standard linear distress signals[4].{ It seems that FM 21-76 was replaced by FM 3-05.70, but the (2002) version I found of that also teaches the standard 5 signals).}

The March 2007 multiservice manual ( Army, Marine Corps, Navy, Air Force) for Survival, Evasion and Recovery [ FM 3-50.3, NTTP 3-50.3, AFTTP(I) 3-2.26) uses the the five international standard linear distress signals[5].

There are many fewer Mission Scanners than potential people on the ground in distress, and the CAP academy already has the proper task training for the CAP ground element.
