Sigh, I meant to say aircraft will need to equip with ADS-B-data-in
and CDTI (or an
*un*-certified traffic display) to see a 1090ES-data-out only
threat...

--

CDTI == cockpit display of traffic information and usually used to
mean a certified product meeting RTCA CDTI specs. Hence the correction
to my typo above.

(and remember here I was discussing the theoretical case of a 1090ES
data-out device is *not* also a Mode S transponder)
