Default ADS-B in and out?

All of our new aircraft are delivered with ADS-B out and all of them should be broadcasting OUT by now or soon. Do any of you have ADS-B IN displayed? We don't and the fleet chief says it may be a few years before we see it on our 737s.

Thatís lame. I have it on Foreflight for my bug smasher flying. Itís unreasonable not to have it on a commercial aircraft doing far moreflying.

I saw a picture of flight numbers displayed on an Airbus screen. So I think itís definitely possible.

With all the PMA and TSO hoops to jump through air carriers are usually the last folks to get new technology. And the cost has to be justified to the higher ups. Out was mandated by the FAA so they had to comply, in is just another video game for the pilots.

Airlines are not in a hurry for ADSB in since we have TCAS for traffic and radar, acars and now WiFi for wx and nexrad.

This, no need to spend money since TCAS does the same thing, perhaps with slightly less accuracy.

Maybe, I don't know if TCAS is reading ADS-B for conflict resolution. The hardware and software would most certainly have to be updated. I'm wondering how long until the transponder rule goes away...

Legacy TCAS installations are not reading ADS-B to my knowledge, that would be another hardware update.

ADS-B based TCAS would provide better and more reliable target resolution but right now legacy TCAS covers more targets because most GA planes have transponders whether they need them or not. That's not the case for ADS-B, so for airliners you'd still need legacy TCAS for a good long while. At least I want it.

With a few exceptions - and those mostly in uncontrolled airspace - all general aviation aircraft must have ADS-B out by 1 Jan 2020.

This will provide BETTER coverage and more accurate coverage than TCAS alone. Keep TCAS if you want it but ADS-B - for a GA aircraft - can be had for less than $1000 with a portable unit, probably three times that linked to an in panel MFD. Having something that works even in radar blind spots and updates once a second (vs every 5-7 seconds at the edge of radar coverage) seems to me to be well worth the investment.

https://www.faa.gov/nextgen/equipads...ties/ins_outs/

Granted, closure isn’t any 1000 knots at the merge, but even some RVs can hit 200 knots. In a 400 knot merge with a tiny experimental kit plane it seems ludicrous that the two seater has better capability to insure he misses you with his ADS-B in than you have to insure you miss him with your TCAS when you are flying 121.

Just my personal opinion.

TCAS provides far better collision avoidance than ADSB. It provides specific guidance on what is required to avoid a collision and if the other aircraft is TCAS equipped data links between the two aircraft to coordinate deconfliction maneuvers. ADSB does none of the above.
A very large segment of the GA fleets will not have ADSB on 1 Jan or ever under current rules. They can fly anywhere below 10,500 feet and itís not required unless you want to enter controlled airspace.
