Why am I not getting good ADS-B weather reception in ForeFlight Mobile?

Pixelation on the radar layer in ForeFlight Mobile is normal when receiving weather information while flying because ADS-B weather is low resolution. However, poor weather reception can be due to a number of other factors: Outdated ForeFlight Mobile or Stratus portable receiver firmware. ForeFlight Mobile update App updates can be downloaded from the Apple App Store. To update:

  1. Tap the App Store icon on your iPad home screen.
  2. Tap Updates.
  3. Tap Update on any flight app updates.

Stratus portable receiver update To update receiver firmware in ForeFlight Mobile:

  1. Connect to the Stratus Wi-Fi network.
  2. Go to the Stratus Status page.
    1. Tap Maps on the bottom navigation bar.
    2. Tap the settings icon located at the top of the screen.
    3. Tap the name of your Stratus receiver under the “Devices” heading to open the Stratus Status page. If the pop up menu says “Stratus Status” at the top, you are already on the Stratus Status page.
  3. See if there is a firmware update available under the top “Device” heading.
  4. Tap Tap to Update to install the update, if there is one. If there is not an update, you will see your current firmware version.

You’re on the ground ADS-B doesn’t work on the ground. You will only get ADS-B reception while in the air. Connection issues Verify that the receiver is connected to the Stratus Wi-Fi network.

  1. Tap the Settings icon on your iPad home screen.
  2. Tap Wi-Fi on the left navigation bar.
  3. Ensure that the Wi-Fi switch is enabled.
  4. Tap the Stratus wireless network name under the “Choose a network” heading. Newer receiver models have the wireless network name on the back of the device. Once your device is connected to the Stratus wireless network, a checkmark will appear next to the network name.

Coverage issues Check the ADS-B map at www.appareo.com/ads-b-coverage-map to see if there is coverage where you are flying. Range or line of sight issues If the ADS-B LED is off: This indicates that you may have a range or line of sight issue. Make sure that you have line of sight with the towers. If you do not, your signal will be blocked. This could be due to physical obstacles such as mountains or flying at an insufficient altitude. If the ADS-B LED is on:

  1. Go to the Stratus Status page in ForeFlight.
    1. Tap “Maps” on the bottom navigation bar.
    2. Tap the settings icon located at the top of the screen.
    3. Tap Stratus V (where the V represents your receiver’s version), located under the “Devices” heading, to open the Stratus Status page. If the pop up menu says “Stratus Status” at the top, you are already on the Stratus Status page.
  2. Under the “Data” heading, look at “Local Radar Update,” “Text Update,” and “Receiving From” to see when you last received data. If signal quality is poor or you are not receiving from very many towers, check the coverage map at www.appareo.com/ads-b-coverage-map. Stratus portable receivers are not functional in Canada, Mexico or any other country outside of the U.S. Note: A green ADS-B LED on the receiver only indicates that the device is receiving ADS-B signal, and doesn’t directly indicate what weather you will see.

Layer issues Verify that you have the “Radar” layer selected on the “Maps” page. Altitude issues You should be at an altitude of at least 500-1,500 feet AGL and below 20,000 feet AGL.
