“A NA(Alternatue Minimums Not Authorized)” symbol and WAAS

Asked by: 3654 views General Aviation

AIM 1-1-18, 8(a) states that "The FAA has begun removing the "A NA" (Alternate Minimus Not Authorized) symbol from select RNAV (GPS) and GPS aaproach procedures so they may be used by approach approved WAAS receivers at alternate airports."

Does that mean, if there's a "A NA" symbol marked on the chart, the chart still cannot be planned as an alternate airport approach even if I have WAAS?
