The relative altitude of traffic targets displayed on the map and/or in Traffic Radar is arguably the most important information about a threat.
The relative altitude is currently included in the label belonging to the target (both with ADS-B target symbols, and with TPX-C related alert rings). For example "+0.8", or "-0.3", standing for 800 FT above, or 300 FT below respectively. The text size is:
- Controlled in the "Mapping" settings
- Linked together with the text size for all other waypoints, airport names, etc.
- And is limited to 140% of default text size
When a new traffic threat appears, I find it difficult to very quickly read the relative altitude:
- Even at 140% the writing is still small (after all the tablet 'vibrates' on a RAM Mount arms, and light conditions may be less than ideal)
- The most important + or - sign is really difficult to tell apart (after all, the difference between + and - is only a few vertical pixels on the screen, but it may be the difference between life and death up in the sky).
Therefore my suggestions are (not withstanding an entirely different, better way of doing it that the clever people at SD are capable of coming up with):
- Separate the settings for Traffic Label text size from the general text size settings
- Allow a wider wider range to set the text size (e.g, up to + 300%)
- Find a better way of differentiating between "above" and below" targets (I have no suggestion here how to do it - you'd need to play around with it)
