Smackey,


not sure about your 1. but

2. I assume that the traffic warning in the mode-s will not alert to
traffic if I'm not in a mode-s area, and/or there are aircraft only
only squaking mode-c or other. In other words, if I'm fling along out
in the hinterlands (a frequent occurance) where there is no mode-s,
the traffic warning is nonexistent!! Wouldn't I do just as well with
a portable Monroy, or similar, traffic alerter?


You will see all traffic ATC sees, including Mode C (and A, and possibly
primary). The mode S in YOUR aircraft is used to uplink the ATCtraffic
data from the radar ground station to your transponder. If the radar
station is not TIS-equipped, this uplink will not happen. So, the lack
of TIS in the hinterlands is due to a lack of radar ground station
equipment, not the equipment of other aircraft.
