Blackthorn, just to check, you are waiting at least 5 minutes for it to appear on the network?  When my local aircraft transition to network, it normally takes 5-6 minutes for the aircraft to appear.  There's the 5 minute delay, and then the network only updates every minute.

And then there's the 2 minutes of local timout in your settings.

No if I don't switch of local it does not reappear on the Network so if I am tracking a flight and I lose it I then disable local flights wait approx five minutes and up it pops.

There might just be something in this.  Following my EZY38CR from live to Network, it disappeared from live at 1020 UTC and by 1029 it hadn't reappeared on the Network.  I deselected Process Hardware Flights and it appeared as a Network track - of course, it might have reappeared anyway without switching off Process Hardware - who's to know!

Allocator, I've seen that effect also.  I suspect that you're picking up your own traffic echoed back on the network, delayed 5 minutes.  I tried this with an aircraft on approach to Aberdeen.  By switching local on and off, I could get the aircraft's altitude to change even though the aircraft remained in exactly the same position.  I put this down to the different QNH settings for my location vs. the location of the other user receiving this aircraft.

Turning ON local traffic forces RB to use the other users sharing.  Turning OFF local traffic allows RB to use my 5-minuted delayed feed to echo back onto my own map.  With a couple of minutes of timeout also factored in.   If that makes sense.

In the case of the COA I tracked I lost it on local overhead Grimsby (Max range for me), I switched off local and switched it back on 6 mins later it reappear on network just East of Grimsby and I tracked it all the way to Schipol where it has just landed.

The true test is to just leave Hardware Processing on and wait until the aircraft appears on the Network - 6 minutes is just too close to the 5 minute Network delayed time.

The trouble is here, that no two aircraft will be the same, so it's difficult to tell if the aircraft is appearing because of what you are doing, or if it was about to appear anyway :-)

Okay Allocator, I will pick a flight and track it leaving local on.

Tracking CSA643 west/east overhead Doncaster

Lost local at 11:03

Report back soon.

I can see CSA643 at 11:10 - looks like it's been there for 2 or 3 Network updates?  FL339 and climbing.

It is not there for me after 10 mins just switched off local and it has appeared over the North Norfolk Coast.

So for some reason the transition from Local to Network does not happen for me but at least I know all I have to do is switch off local flights.

But it would be better if we can establish why it's not working for you, whereas it works okay for other users.  At least then Airnav might be able to fix it.

To see where the aircraft is on the Network, use the AirNav Live Flight Tracker:

http://www.ruyton.demon.co.uk/html/live_flight_tracker.html

I'm doing that right now with TOM385 which still hasn't reappeared south of BCN having gone through my overhead - it's there on Live Flight Tracker.

Allocator, when I track an aircraft live, for example, going north towards the UK, I'll normally lose it (because of terrain) around the Loire valley - Angers, Tours area (dependent on it's Flight Level).  When it reappears as a network flight (if it ever does) it's normally approaching the Isle of Wight, so I suppose that's getting on for 200 miles.  The reverse is true for southbounds.  There is usually other networked traffic present in the area at the time, and I would expect to see my target aircraft much earlier

Blackthorn, it may well be things can be improved by virtue of temporarily switching off local and switching it back on again, but not always.  This is the subject of many postings and a long-awaited fix!

OK, followed TOM385 on Live Flight Tracker until it was off the south coast of the UK, nothing on RB.  Deselected Process Hardware Flights and Bingo, TOM385 reappeared as a RB Network track.

I can't say I've noticed this happening before, so maybe it's a server logic thing?
