We have a 'basic' TCAS type system fitted to our EC135 and it is a fantastic piece of kit. It doesn't have pull up/down or terrain warnings, just traffic alerts. It doesn't replace lookout either, but it has helped my lookout many many times, I see anything that squawks because the kit tells me to look harder if I miss something. Remember its limitations though, microlites tend not to have transponders so the eyeballs are still number one at low level. The Tucano can only be better with this kit.
