Mode-S Flight ID question

[tarbat]

The military aircraft that only have ModeS but DO display FlightID in the current version of RB appear to transmit their FlightID in a DF17 message.

Yes, I've noticed the odd one like that coming up in my monitor, for example AAC Gazelle XX460/43C0CA, with the Identification/Category squitter.

Like this?   FAGIN52, an RAF aircraft.

I take it that the South Western Dash 8 Q400s transmit the fid over the same frame then?

[tarbat]

I don't think I've ever logged a South Western Dash 8.

Okay, I haven't seen an Air Southwest flight since last year.  However, I see plenty of Flybe and Wideroe Dash 8 402Q's, and these are all now showing FlightIDs in v2.10.

Here's an example on screen now:

[DaveReid]

I take it that the South Western Dash 8 Q400s transmit the fid over the same frame then?

I would assume so, although with SBS it's impossible to tell whether the Flight ID is coming from the Extended Squitter or the ELS DAPs without capturing the message packets.

[mighty3507]

Just a quick update. I have been running 3.0 beta since it was released. I was hoping to see a lot more flight ID's for Mode-S flights. I have seen a slight improvement. (Flight ID's show frequently for Air Canada and U.S. Airways).  Overall, just not the increase I had hoped for.

Attached is a screen shot of what I typically see. It is safe to say that the missing flight ID's are just not being input by the flight crews or is it there something RadarBox can do to pick these up?

It could also be the there's not a ModeS radarhead nearby to send the request.  Explanation at http://www.kinetic-avionics.co.uk/forums/viewtopic.php?p=29693#29693

mighty3507: V3.0 decodes all possible mode-s frames containing flight Id information. So if you don't see them, then it is a matter of improving you reception conditions.

[DaveReid]

So if you don't see them, then it is a matter of improving you reception conditions.

But see also Tarbat's post above. 

If an aircraft that you're picking up doesn't have 1090ES and it's not within range of a Mode S interrogator, then you're not going to see Flight IDs for it, period - no matter how good your reception is.

[Allocator]

I'm fairly sure that I'm getting more Flight ID's vith V3.0 Beta - although this is a pretty poor example as 3 of the DH8D's are not showing ID.

You're unlikely to get a Flight ID for 400930/G-JEDK - for some reason it started sending nulls in this field about 3 years ago, and it's still doing it.
