I am still uncertain of this 4 seater TCAS.

You tell me
I already have a traffic aviodance system (TAS) that works off other aircraft transponders
Can you please advise make and model. As already I have said on here, I am unaware of cheap systems that work off other aircraft transponders WITHOUT monopulse radar ping or equivalent. My understanding that aircraft transponders are passive and only respond to MSSR or equivalent pulse. I understand full airline TCAS works because it pings other aircrafts transpondrs.

I have read JCP. In event of GPS failure there is backup by ADF/VOR/DME navaids retained and primary radar in terminal areas of major airport.

If GPS turned off, I suspect mushroom cloud more to my worry than GPS.
