Colour and size of traffic

I'd like the option to have TCAS-like symbols and text instead of the little images which can be hard to spot against the chart. Another option might be an insert traffic display a bit like the HSI when seated on-screen.

I will move this to the suggestions forum to see if others think it's a good idea to be able to change the size of the icons used for other traffic.

I fully support Stefan's suggestion. At minimum I would welcome the possibility to change size and color of the traffic. I haven't seen any pure Mode S traffic yet (I just recently changed my TRX-2000 settings to also transmit non-directional traffic via Air Connect to SD) and wonder how this currently implemented (is it like the white circle in Stefan's screenshot?). Therefore an HSI like traffic display may be useful as as an option, displaying non directional traffic also as a circle.

‌These suggestions anyway depend on the traffic detection device and whether it has it's own display or not.

Hi
‌I'am using latest SD with Stratux as FLARM device on an iPad mini and can see all traffic around me. But the icons of the planes are in white and a little bit too small. It would be nice to have the possibility to change these settings like the icon of the chosen icon for the type of aircraft itself.

‌Thanks you in advance.

‌Kind regards

Tim,

please make the traffic text size adjustable and everbody is happy.

I am in principle fine with current sizes. As long as a target is not a threat, I really don't want it to clutter the map. When it comes into eyeball reach I want to get it on the map and change color and yes, threats could be a bit bigger on some of the tablets (but definitely not at all).

Would love to be able to configure it to be similar/the same as TCAS type indicators ie hollow/filled white diamonds, yellow circles and red squares depending on relative distance/altitude.

@piperpa28,

I also use SkyDemon on an iPad Mini.

Are you aware that you can already increase the Text Size of the Aircraft Details up to 150% of the original size. This option is in the ‘Mapping’ Dropdown (the ‘layer of papers’ symbol at the extreme lower right of the main screen).

Although I haven’t had significant difficulty seeing the aircraft symbols themselves, I would support an option to be able to increase their size by a similar proportion to the text, though we need to be very careful that they don’t start to obscure more important information.

With regard to colour, the aircraft symbols already change from white to green, yellow, then red if / when they present a higher risk to your aircraft, so any change to base colour would have to maintain effective contrast so as not to detract from this warning function.

Also no objection from me to an option to display aircraft using ATC / TCAS symbols as long as it is an option, not the default.

Finally, @ Tim D... I don’t recollect seeing the large white circle round Ownship (though it has been several months since I have flown). What does it indicate and is this specific to the Stratux FLARM Traffic Source?

Best Regards

Another Skydemon user here who has recently bought a SkyEcho 2  ( thank you Department for Transport rebate  !  )  Colour change for targets generated by the SE2 would be welcomed........  perhaps Yellow at 4 nm turning to red at 2 miles ?

One improvement of the latest beta:

- When flying with a traffic receiver the level of other traffic has been made bold, so it's easier to read

Thank you, Tim, I really appreciate this change. Flew yesterday and a lot of non-bearing traffic was in the air. Made life a lot easier.

I also would prefer a customizable size for the text next to targets and bearingless circles.
By Exfirepro - 3/5/2021 10:04:14 PM

@Maverix

As per my post above, you can already vary the text size of the traffic details between 50% and 150% of the default.

Thanks for your reply.

But only the text size for all details and not specific for the traffic details, right?

By Exfirepro - 3/6/2021 7:34:30 AM

@Maverix

True, but if you need the traffic text larger (or smaller) surely the same applies to all the other text as well?

As I get ever older and need stronger glasses for close work, I can see less and less need for a reduction from the default (which I have never used) and could certainly make a valid case for a greater text size increase than 150%, though we need to be careful not to get to the situation where it obstructs essential detail on the chart below. Perhaps a modest tweak to text size to allow a range of say 75% to 175% of default would be a sensible and reasonable solution. Thoughts everyone....

For me it is much more important to see the level of the foreign targets than the name of the city I am flying over....

When flying VFR, name of the game is: Keep your damn eyeballs out of the cockpit - see and be seen!
The more time we spend to find traffic on a screen, which is already cluttered with map and other data, the more this could in the end have deadly consequences. This is the reason, why professionals prefer an easy to read, one glimpse to catch traffic warning display.
Therefore I still propose to have some simple mechanism to get the pilots attraction, provide a clear cut simple to interpret indication where to train the eyeballs on and how imminent the danger is. The earlier relevant warnings come, the better dangerous situations can be deconflicted. The way SD provides this service is already quite elaborated and of help, but as usual, the is room for improvement.

Therefore I propose a combination of audio alerts when conflicting traffic presents in yellow or red (should be really noisy when status changes to red), the flashing presentation of this relevant traffic on an easy to read pop-up screen (eventually HSI), which remains on top of the display until a) acknowledged by the pilot (i.e. tally-ho) in typical SD fashion or b) situation is deconflicted due to appropriate action.
Your thoughts?
By Exfirepro - 3/11/2021 4:44:36 PM

Hi Peter B,

Audio warnings are (quite rightly) the primary means of bringing conflicting traffic to our attention. These are backed up by the fact that in most instances the presence of traffic will already have been picked up during Visual Scan of the ‘instruments’ when it is further out - often well before it comes in visual range. We also already have the colour changes as the risk gets greater.

We have to be careful with picking colours to ensure they are clearly visible against the background even by those who may have minor colour vision issues and care must also be taken with flashing symbols as these can induce issues such as epilepsy with anyone (pilots or passengers) who might be susceptible to this type of ailment (but might not even be aware of this).

There certainly may be a case for ‘auto-enlarging’ the symbol for traffic when it turns Red, to draw attention to it, but other than that, IMO the current system works pretty well.

Hi Peter,
IMHO pilots with epilepsy or tendencies to this sort of ailment do not belong into the cockpit of any airplane, and having avoided an epileptic attack with my passenger but encountering a mid-air instead - what is more desirable? Look at a simple FLARM indicator in a glider: When things get rough, this little bastard screems and blinks like hell to wake you up... and that's the purpose of all of this.
Maybe I am old fashioned, but when flying VFR I spend 80 to 90% of my time heads up, 5% on the map (paper) and the remaining time on instruments, displays and passenger. This was proven concept to survive 45 years in all sorts of close-to-the-ground and f**g fast speed missions - I love simple, but effective triggers which need no interpretation time, and the older I get, the more I prefer it just like that ;-)

Peter

People asking for a colour change as traffic gets closer or becomes more of a threat: that's the way it already works.

Peter, I don't know what the white circle is either. I don't think we have such a thing in SkyDemon.
By Sfera72 - 2/21/2021 8:27:59 AM

I also think, that it‘s important to change the color and size of traffic. Please make it possible.
By fokus - 2/22/2021 3:00:12 PM

Very good Idea!!!
What about changing color and size depending on the distance to the target, if it is not to much work to code it?
By efrenken - 2/22/2021 8:03:27 PM

Yes, I second Peer’s idea.

And Tim, please let us customise the script near the white circle (relative altitude). When I was flying yesterday I found myself head down in the cockpit searching for the numbers near the circle. Sometimes there is no chance seeing it while the circle increases and decreases its diameter every 1-2 seconds.

Thank you.

Eric
