Title: Aircraft symbols facing North, flight heading SouthEast?
Post by: TGA388 on January 04, 2010, 05:51:31 PM

Hi all, has anyone else noticed this? I seem to get this only on Kuwait Airways 772 flights and a very few BA 772's.

It is very odd as the flight direction is generally SouthEast, but not always, and the aircraft sysmbol is facing North, causing it to look like the flight is tracking sideways or even backwards!

It is not a major problem and it is not unique to V3.13, does anyone know why this happens?

Update: I have added a screenshot (hopefully) to show this happening. BA198 heading NorthWest  to LHR G-VIIM is the aircraft involved.

Best regards, Dave

G-VIIM often fails to send either track or groundspeed (which is why the latter is missing too in your screenshot).

RadarBox interprets missing track data as a bearing of 000 degrees, which is why the aircraft symbol is pointing north.

Many thanks, that explains why I get this 'problem' I guess we will just have to live with it.

Best regards, Dave.

Thanks, I wondered why this happened. In my case it's the Kuwaiti 777 9K-AOA that always seems to point north

Yes, unlike G-VIIM above, which sometimes sends track, 9K-AOA never seems to (in common with quite a few other 777s).

Ironically these aircraft, and all the other 777s that don't transmit track, do send heading - perhaps a future version of RadarBox could make use of this information to orient the aircraft symbol correctly ?

Here is another culprit:

G-MANH ATP Mode-s 400749 Atlantic Airways

Screenshot attached.

Many of the ATPs I see appear to be stationary over West Africa! Feel lucky you see one over the correct country ;-)

The ATP is so slow it often flies backwards in a strong headwind  :-)

I have problems with the Air Hong Kong A300s, which always face north no matter what direction they are actually flying. Heading always shows 360 in the list of flights and the aircraft symbol always points to the north.
