Premium trial period extended from one to six months for existing or new downloads before the end of June 2021.
See previous news item.
The following features are scheduled to become premium features from July 1st 2021.
* all new features
If you have already downloaded AvTraffic or do so before July 1st, you will get free premium access until December 31 2021.
After July 1st, the free trial period will be 1 month from download.
The subscription will be $1.99 per month or $19.99 per year (AUD) or equivalent in your local currency.
Please note that one subscription covers all your devices.
You will still be able to use AvTraffic's own traffic display without a subscription.
Cater for the case where an aircraft has both a mode S transponder and a FLARM unit and the callsigns are different.
This is common for gliders in Europe where the Mode S callsign is the full registration say DABCD but the FLARM callsign is just CD.
The stability issue could occur when an external ADS-B receiver is in use resulting in JSON errors and missing aircraft type data.
Multiple sources might occur for example where a target aircraft has ADS-B out and also active AvTraffic at the same time.
A server outage occurred back in March that lasted for two days and resulted in a continuous stream of error messages. If this occurs again, only a single error will appear and the server marked as "Down" in the status view until it recovers.
New option to show or hide airports. Airports are shown by default.
At this time the Open Glider Network live service has been down for about a day. AvTraffic has no control over the operation of this service and we are simply waiting for the service to be restored.
AvTraffic is currently showing alternately that the service is 'slow' or has a 'network error'. It is retrying the connection every couple of minutes and is continuously showing a series of warnings and error messages.
Please ignore these messages and the red cross in the status for the time being.
AvTraffic and ADSB Exchange are still working and will continue to show traffic from those sources as normal.
In a future release, server outages will only generate a warning once and reconnect when the service comes back up.
If you use a portable ADS-B receiver such as the SkyEcho 2 with your EFB app, AvTraffic will now merge its own traffic sources with the receiver's traffic for a more complete picture.
To enable this, go to the Options screen and switch on the "Portable ADS-B" switch.
The status page will have an extra Service line showing the receiver and its target count. Don't forget you need to be connected to the receiver's WiFi network.
Some significant updates to altimetry.
Devices with a barometer now report pressure altitude as well as GNSS altitude. This enhances vertical separation with ADS-B traffic.
All altitudes are rounded to 100 feet with a prefix -
For example, G010 means 1000' GNSS or GPS, A010 means 1000' AMSL on local QNH.
See live traffic, current and recent flights, get a METAR or decode any airport code globally.
Click the LIVE menu on the AvTraffic website.
ADS-B Exchange has a new interface that reduces the time delay of displayed aircraft positions.
Extra detail for selected aircraft includes the closing time if the aircraft is closing plus its bearing and distance. The closing time is coloured blue, yellow or red as per the map symbols. On the map, see the aircraft's prior track.
Use a pinch gesture to zoom the traffic display. Use the zoom buttons to zoom to preset levels.
When you use AvTraffic while flying, don't forget to select your aircraft and select active (ACT) mode.
Use the toolbar buttons at the top right to select your aircraft and mode. Refer to the app's Help tab for more.
Please note that after upgrading to iOS 14, you will be asked to permit AvTraffic to "Access devices on your local network".
This is referring to the connection AvTraffic requires to send traffic information to AvPlan or OzRunways. You need to allow this in order to continue to send traffic between apps.
You will get asked the same question when you first run OzRunways or AvPlan and you need to allow this for them too.
You can change this in Settings/Privacy/Local Network.
On the status view you can now see the METAR for the nearest airport that has one.
Please note that METARs are only updated hourly and as such may not be the latest for the given airport. The information is provided for reference only and must not be used for making operational decisions.
The app is now using the QNH to convert between GNSS and pressure altitude internally.
The pressure altitude is now displayed as a flight level (Fnnn).
The EFB interface for sending traffic now uses the GDL90 protocol exclusively. The old dump1090 protocol is no longer available.
This means that the EFB configuration steps defined for previous releases is no longer necessary.
AvTraffic is now able to send traffic to any EFB using the GDL90 protocol.
This is great if you're a new user because you won't need to configure OzRunways or AvPlan with the special IP address as previously documented.
However, for the time being, you will need to go to the Options view in AvTraffic and switch on "Use GDL90 for EFB".
In the next release, GDL90 will be standard for all users.
PS - Don't forget to select active (ACT) mode when you're flying.
External ADS-B receivers report pressure altitude. Because of this, EFB apps need to adjust altitudes for local QNH.
In the past, AvTraffic has always dealt in GNSS altitudes and passed them directly to the EFB app.
In this release, AvTraffic now converts GNSS altitude to pressure altitude before passing it to the EFB app so it ends up being correct.
In order to do this, AvTraffic uses available ADS-B data from from nearby aircraft. You can monitor this on the Status View.
This month, Geoscience Australia in partnership with FrontierSI, University of Otago and RMIT have started investigating the issues and challenges to enable precise positioning for smartphones.
Over the next 2 years, they will be working toward obtaining centimetre-level positioning on mobile phones.
At the moment the team is going through a process of deciding which phone to test first and will be looking at how to manage data quality. Stay tuned for more developments as they come.
From July 16th, VFR aircraft in Australia not equipped with ADS-B Out will be able to use Electronic Conspicuity (EC) devices such as the Sky Echo 2 which sells for AU$900.
This will allow VFR aircraft in class G airspace to be seen by ADS-B In equipped aircraft including AvTraffic users.
Only bug fixes in today's release.
The traffic monitor in V3.4 and earlier creates traffic alerts based on distance alone.
Now, based of the aircraft's speed and track, it becomes a high alert when the closing time is less than a minute instead of a distance of two miles. If it is tracking away, no alert is raised even if it is close by.
If you have connected audio, the alert is spoken using a speech synthesizer instead of just a tone.
The spoken alert takes the form -
"Traffic - [distance in miles] [clock bearing] high/level/low"
The new history view shows the departure and destination points and times and the distance travelled.
The old aircraft selection button has been split into two, one to select the current aircraft being flown and a second button to select the mode - Active or Standby. This makes operating the app more like operating your transponder.
The Start/Stop button has been removed and both the Filter and Orientation buttons are now on the left.
Lastly, you can add a description to your aircraft. For example if you fly an AP22, you can set the description to "Aeroprakt Foxbat" which should be more meaningful to other users.More News Archives
