Ram, if I recall that incident correctly, ATC had repeatedly requested a
heading change and direction of turn (don't recall actual numbers) but
the
flight crew repeatedly read back incorrectly. In the end the controller
deferred to the "obviously" more experienced and knowledgeable captain -
and
gave in...

With respect to the capability of TCAS - it only interrogates the
transponders of nearby airplanes. It then figures out their distance
away,
bearing and delta altitude (assuming a mode C or S transponder). It will
give a Resolution Advisory (Climb or Descend) instruction. It does not
give
any terrain warning.

Maybe if we put mode C Transponders on every mountain top... And radio
tower
for that matter.


Ummm...doesn't TAWS read a map database that holds such obstructions?
