Capt Fathom - to answer your question - FAM, and the TACM.
Companies such as Qlink, EFA, REX etc. are able to log PICUS from the right seat on PF sectors, provided they meet certain licence requirements, hence the confusion for some people and why it doesn't just state 500hrs multi-command like the good old days (circa 2007 for
VB etc).
Clear as mud? Yep...
