Traffic
I'm running AvTraffic with my EFB but I'm not seeing extra traffic. 
Check the EFB status by tapping the status button (green circle, warning or error symbol) on the bottom right of the traffic view.
Under "EFB Connection", it should show "Sending traffic (n)" where "n" is the number of targets being sent.
The most common reason for AvTraffic not sending traffic data to the EFB is that you are in standby (SBY) mode.
Enter your aircraft details and make sure it's selected.
Make sure the mode is active (ACT).
Check these two things on the right of the title bar on the traffic view. You should see your callsign next to the mode button.
Check "Local Network" under Privacy/Settings. Both your EFB app and Avtraffic need permission to access this in order to send and receive traffic between each other.
Additional requirements for OzRunways -
- requires one of the Premium subscriptions (IFR or VFR) to enable traffic from an external device including AvTraffic.
- Enable GDL90/Stratux/Flightbox must be on (see Settings/Device Options).
- Enable Dynon SkyView may need to be be off.
Additional requirements for Air Nav Pro -
I'm running AvTraffic while connected to a portable ADS-B device but I'm not seeing extra traffic.
If your device is connected to the local wifi of a portable ADS-B receiver you need to switch on the "Portable ADS-B" switch in settings.
This sets up a relay whereby AvTraffic forwards the messages from the device to your EFB.
The relay service uses extra resources so if you don't use a portable ADS-B receiver, switch this setting off.
I'm running AvTraffic with OzRunways. What extra traffic will I see?
AvTraffic shows ADS-B, Mode-S, Gliders and other AvTraffic users. Having integrated to OzRunways you will see all this on OzRunways plus its users of course.
If you use an external receiver such as the SkyEcho, this will give ADS-B traffic even when there is no cellular connection.
Apart from the extra traffic you will also benefit from traffic alert annunciations.
I'm running AvTraffic with AvPlan. What extra traffic will I see?
AvPlan already displays ADS-B and gliders as well as its own users.
Integrating with AvTraffic will show you other AvTraffic users not on AvPlan.
Sign In
Oops, I forgot my password.
If you've already signed in to one device, just go back and enter another password. That will reset it.
You should then be able to use the new password on your other devices.
Note that after you've signed in you can also change your email address as well as your password. The changes will be reflected across all devices.
FYI, passwords are hashed in the server. It's impossible to recover a forgotten password.
I signed in with my old email, how do I change it.
On any device that’s already signed in just go into settings/sign in.
Enter your new email and a password and tap sign in and it it will update.
On each of your other signed in devices, the new email will show after the next re-launch.
Subscriptions
I have a current subscription but the app tells me I haven't.
If you have a current subscription but the Settings/Subscription page shows that you don't, try a refresh.
This can happen after transferring your data from an old device to a new one for example.
To fix this, tap the refresh button on the top right of the Settings/Subscription page.
How do I manage or cancel my subscription?
To change or cancel automatic renewals -
- Open iOS System Settings
- Tap the box at the top with your name
- Tap Subscriptions then do any of the following -
- Change or cancel an existing subscription
- Resubscribe to an expired subscription
GDL90 Devices
What does 'GDL90 device unavailable' mean?
Most EFB apps open a 'port' to receive traffic messages from a GDL90 device.
When you see this message it indicates that the EFB has started first and has grabbed the port exclusively preventing AvTraffic from gaining access.
You can avoid this by starting AvTraffic first.
Please refer to the special considerations regarding GDL90 devices help page.
Note that this only applies when you have the 'GDL90 device' setting switched on.
General Questions
I'm seeing the message "AvTraffic Slow", what does it mean?
During normal operation, AvTraffic connects to the AvTraffic server, ADS-B Exchange's server and the Open Glider Network server to collect traffic info.
If one or more of these servers hasn't responded by the time the next call is due, AvTraffic displays the "slow" message.
This is normally due to poor cellular coverage and should clear when coverage improves.
What is the latency or delay present in the traffic display?
AvTraffic uses a sophisticated prediction model to show accurately where an aircraft is at any given instant.
Because each fix is timestamped, the receiver can predict the target's actual position with great accuracy by applying a correction based on its track, ground speed and vertical speed.
This predicted position is the one displayed on the traffic screen and also sent to your EFB once per second.
The timing of position reports and traffic queries varies according to demand. When an aircraft is in close proximity, the average latency is about five seconds. This increases to 10 or 15 seconds when flying and no threat is imminent. When on the ground it increases to 20 seconds.
