I was speaking with a couple of Global Hawk pilots at Beale this
weekend and got some interesting information. The information was
presented to me as public (non-classified).

T'ain't a pilot if you aren't in the aircraft. :-)

The first thing that
surprised me is that contrary to whatI had heard previously the
aircraft has no traffic avoidance systems at all. There is a bay for a
civilian TCAS unit but as of yet none have been installed. The pilot
reported that certification of TCAS was interrupted because TCAS
resolutions require 30 degree of bank and the GH is limited to 15.

um, no. TCAS II resolutions are vertical only. No TCAS II resolution requires
a turn. TCAS II azimuth information simply isn't accurate enough to support
horizontal guidance.
