I see we now have other aircraft in view in OzRunways. Is this the same as we’d see on ADSB in?

Yes, however it is relying on the other aircraft's adsb transponder being picked up by a ground reciever and that data then sent back to your aircraft by the mobile network. Could be patchy or non existent. (This is the way a government might do something) 

 

Having an adsb transponder and a absb reciever in your aircraft will ensure you will see and be seen by ALL nearby aircraft that are so equipped. (This is the way an individual that needs something done would do it).

Similar but not the same.

 

As Thruster88 said it uses ground based receivers then sends data to your iPad via the internet.

Data may be incomplete and is a little behind.

 

I would disable internet based traffic when in the air if OzRunways lets you do this.

I believe OzRunways includes locations of other OzRunways users based on their internet iPad sent position (even if they have no ADS-B).

Delayed data can cause problems of its own and I believe the negatives outway the positives.

An ADSB IN receiver is:

  • Not much good if you don't have the ancillary systems to "see" the transmitting aircraft
  • Overkill, for small recreational air craft , when you can use an SE2, which will display ADSB IN on an iPad (OzRunways)
  • Wont display the older, still legal, transponders (Mode S?)

Keep in mind the government is going to subsidise the cost up to $5000. Why not take advantage of that and improve safety for yourself and everybody else.

Some ADS-B in/out transponders, such as the Garmin GTX345 will feed audio alerts into your intercom and well as bluetooth data to your iPad.

"Traffic 2 oclock high less than 1 mile" is very useful.

This transponder has everything built in and just needs an audio input.

 

I do not know of any display (except ATCs) that will display mode S (non ES) or mode C or mode A.

 

It appears future (soon) access to controlled airspace will require a mode C transponder or higher.

A SE2 alone will not give you access.

For many of us, cost of an ADSB system, is a significant factor, even with the Gov rebate.

All true however, if cost a factor in the transponder question - go for an ADSB OUT and an SE2.

 

The ADSB OUT will meet the entry to CTA  requirements.

 

SE2 is a low power ADSB in & OUT devise, which will make you conspicuous to aircraft with ADSB IN  and/or an  SE2,  within about 10Nm +.

 

Your EFB (OzRunways or similar) will link to your SE2 and display aircraft with ADSB OUT, SE2 & OzRunways 

 

Unfortunatly "legacy" transponders, which are certainly still around in my area, will not display.
