Stratus Pilot’s Guide
Carrying bag
Stratus is a portable, battery-operated receiver that works in conjunction
with the ForeFlight Mobile app. It provides pilots with free in-flight weather
and traffic and is a source of accurate GPS WAAS position. Stratus
receives Automatic Dependent Surveillance - Broadcast (ADS-B) weather
information (FIS-B), traffic information (TIS-B), and other related data and
broadcasts it to ForeFlight Mobile via a WiFi network.
Stratus is also an attitude heading reference system (AHRS) and flight
data recorder. See page 13 for more information about these features.
Your Stratus will automatically be registered with the retailer at the time
of purchase – you do not need to perform additional steps to activate
the warranty. The Stratus Limited Warranty is valid one year after your
device is shipped from the retailer and is non-transferable.
Visit www.sportys.com/stratus or www.appareo.com/stratus for a list of
compatible Stratus accessories, including mounts, external antennas, and
Press the power button for a few seconds to turn on Stratus. All LED
indicators will briefly illuminate red and then green as Stratus powers on.
Fully charge Stratus’s battery prior to first use. To charge the battery:
1. Insert the USB plug of the charging cord into the wall charger’s port.
2. Plug the micro USB plug into Stratus’s charging port, as shown in the
graphic on page 5.
NOTE: The Stratus USB port contains two parts. Insert the charging
cable into the larger, left part of the port, which is marked with the
battery symbol.
3. Plug the wall charger into an electric wall outlet. When connected to
an external power source, the Stratus Power LED will flash on and off
once. Refer to the LED Indicator table on page 10 to determine when
the battery is fully charged.
NOTE: You may check the battery’s current charge level from the Stratus
Status page. See page 14 for more information.
WARNING: Use of non-approved battery chargers may result in
decreased battery performance, permanent damage to the USB port, and/
or inoperability of Stratus, and voids the warranty. Stratus requires a 2.0
amp charger.
If Stratus is not connected to an external power adapter, such as a wall
charger or vehicle power adapter, it will automatically draw power from its
internal battery.
You may select how Stratus is powered on: automatically whenever the
device receives power, or only when the power button is pushed. This
setting may be changed by dragging the “Turn on When Powered” switch
in the ForeFlight Mobile Stratus Status to ON. For more information about
the Stratus Status Page, see page 14.
NOTE: If Stratus is set to automatically power on and external power
is removed, it will power off within two minutes if the aircraft is traveling
under 5 knots. If the aircraft is traveling faster than 5 knots, Stratus will
not power down and will draw from the battery power. To override the
automatic power-off, press the power button after removing power.
The snap-in mount secures Stratus to its mounting location during flight.
To place the mount in the aircraft:
1. Remove the protector sheet from the gel base of the snap-in mount.
2. Place the gel base of the snap-in mount onto the aircraft’s glare shield.
Stratus should be mounted perpendicular to the back of the aircraft
to ensure accurate AHRS data. It should also be placed as close as
practical to the pilot and copilot seats to help prevent overheating.
3. Lay Stratus in the snap-in mount so that it is leaning against the longer
arm of the mount’s cradle. The LEDs and Stratus logo should face the
back of the aircraft. If Stratus is facing the wrong direction, AHRS data
will be incorrect and the chance of overheating will be significantly
NOTE: Refer to the graphic on the bottom of Stratus for the correct
mounting alignment with the aircraft.
4. Press on the top of the Stratus until the device snaps into place in the
cradle, as shown in the figure on the following page.
NOTE: An optional suction cup mount is available from your Stratus
retailer. This mount may improve the internal antenna’s ADS-B reception
and provides an option for mounting Stratus off the glare shield.
To remove Stratus from the mount:
1. Gently bend the shorter arm of the mount’s cradle away from Stratus.
2. Remove Stratus from the snap-in mount.
Store Stratus in its carrying bag to protect it when it is not in use.
If the gel base that surrounds the snap-mount loses its adhesiveness over
time, remove the gel base from the mount and wash with water and a
gentle soap. Allow it to air dry before placing back on the glare shield.
NOTE: Remember to disconnect all cables from Stratus before removing
it from the mount. Improper disconnection of cables from Stratus can
damage connectors and/or ports.
Stratus contains internal GPS and ADS-B antennas; however, external
GPS and ADS-B antennas are also available from your Stratus retailer.
These antennas may improve Stratus’s reception quality and provide more
mounting options for Stratus.
Place the external ADS-B antenna in a location of your aircraft that
provides an unobstructed view of the ground (ADS-B towers).
Place the external GPS antenna in a location of your aircraft that
provides an unobstructed view of the sky (GPS satellites).
When mounting either external antenna type, ensure the connecting cable
is long enough to route from the external antenna to Stratus’s mounting
The ports labeled “GPS” and “ADS-B” on the side of Stratus are for
connecting external antennas. To connect Stratus to an external antenna,
insert the external antenna cable connector into the respective Stratus port
and use the suction cups included with the external antenna to place the
antenna in its mounting location.
WARNING: Ensure you are connecting the antenna to the correct port.
Inserting the antenna into an incorrect port may result in permanent
damage to the port and/or the antenna.

*If Stratus battery is above 45°C (113°F) and Stratus is connected to external power, it will
continue to draw power from the external source but will not charge the battery. When this
occurs, the Power LED will be yellow. You may confirm if a battery is charging from the
Stratus Status page (see page 14 for more information).
Your iPhone, iPad, or iPod touch must be connected to the Stratus
wireless network for Stratus to communicate with ForeFlight Mobile or
Stratus Horizon. All iOS devices in the cockpit may be connected to
Stratus simultaneously.
1. Tap the Settings icon on your device’s home screen.
2. Tap WiFi.
3. Ensure that WiFi is enabled (the WiFi switch should reveal ON).
Tap the Stratus wireless network, displayed under Choose a
Network... to connect.
Stratus’s wireless network name will be displayed as
“Stratus2XXXXX,” where the X’s represent your Stratus’s unique
five digit serial number.
Once your iOS device is connected to the Stratus wireless
network, a checkmark will appear next to the network name.
4. Confirm that Stratus is connected in the Stratus Status page of
ForeFlight Mobile or Stratus Horizon. See the Stratus Status Page
section on page 14 for more information on this feature.
ForeFlight Mobile users can use Stratus for backup AHRS (altitude,
heading, and reference system) to enhance situational awareness. For
the most accurate AHRS information, ensure Stratus is mounted parallel
with the centerline of the aircraft and the logo and LEDs on the device
should face the back. Refer to the graphic on the bottom of Stratus for the
correct mounting alignment with the aircraft. Mounting Stratus as level as
feasible will also help to achieve the most accurate AHRS results.
Stratus has a flight data recording feature that, if enabled, will
record position, speed, attitude, and altitude data during each flight.
Approximately 20 hours of data can be stored in Stratus’s built-inmemory. After your flight, you can export your Track Log data and display
the flight in a supported app or share on many social media platforms.
To extend your battery life, you may turn your iPad screen off or switch
to another app. Once you return to ForeFlight Mobile, Stratus will
automatically send any missed ADS-B weather information to it.
For more information about any of the features on this page, refer to the
Pilot’s Guide for ForeFlight Mobile, which is available on ForeFlight’s
website and within the app.
Once Stratus is connected to ForeFlight Mobile or Stratus Horizon, you
may view information about your device and adjust settings via the Stratus
Status page in the app. To access the Stratus Status page in ForeFlight
Mobile, tap Devices while in the More view. Then tap the “Stratus,
Connected” box. To access the Stratus Status page in Stratus Horizon, tap
the white information (i) button.
The Stratus Status page displays general information about Stratus in
both apps, such as its current battery charge, serial number, and firmware
version. The Stratus Status page in ForeFlight Mobile also displays the
number of ADS-B towers Stratus is receiving data from, and allows you to
adjust the LED brightness and turn on power saving mode.
Please refer to the pilot’s guides for ForeFlight Mobile and Stratus Horizon
for more information about the Stratus Status page and interacting with
Stratus contains an ambient light sensor that will brighten or dim the LEDs
in response to the ambient light level. You may also manually change the
LED brightness settings using the LED Brightness slider on the ForeFlight
Mobile Stratus Status page.
Stratus receives ADS-B weather data and relays this information to
ForeFlight Mobile. The table below lists the weather information that is
available from ADS-B broadcasts. See the FAA’s Aeronautical Information

Stratus receives UAT and 1090 ES traffic information from ADS-B ground
towers and ADS-B transmitter-equipped (ADS-B “Out”) aircraft and relays
it to ForeFlight Mobile.
If air traffic is detected by Stratus, it will display in ForeFlight Mobile
relative to your aircraft. Refer to the Pilot’s Guide for ForeFlight Mobile
for more information on how traffic data is displayed within the app.
Air-to-Air Traffic
Please be aware that Stratus will only receive air-to-air broadcasts from
other aircraft if they are ADS-B Out equipped and within range of Stratus.
Air traffic that is not equipped with a Mode ES or UAT ADS-B Out
transmitter will not be detected by Stratus air-to-air.
Rebroadcast Traffic
Using its network of ADS-B ground stations, the FAA can rebroadcast a
custom traffic report to ADS-B Out equipped aircraft that are within a 15
nautical mile radius and 3500 feet in altitude of the traffic activity. If your
aircraft is not ADS-B Out equipped, it will not receive rebroadcast traffic
unless it happens to be within range of an ADS-B Out equipped aircraft
that triggers it. If your aircraft is ADS-B Out equipped but is not in contact
with an ADS-B ground station, it will not receive rebroadcast traffic.
The FAA can rebroadcast traffic information about aircraft equipped with
the following transponder types: Mode C, Mode S, Mode ES, and UAT.
Mode A transponders and primary radar targets detected by the FAA are
not included in rebroadcasted traffic reports.
Since not all aircraft are ADS-B Out equipped and not all traffic is
rebroadcast, the use of Stratus does not preclude pilots from having to
perform see-and-avoid procedures.
Stratus is not an active traffic interrogation system nor is it an ADS-B Out
NOTE: Your Stratus will likely not receive weather or rebroadcast traffic
information on the ground as ADS-B information is broadcast by ground
towers. The altitude Stratus begins to receive weather and rebroadcast
traffic information will vary depending on the distance to nearby towers,
and terrain and other obstacles that may be between Stratus and a
Occasionally, Stratus firmware updates will be released. These updates
may activate new capabilities or address known issues. If a firmware
update is available, it will be sent to your iOS device as an update to
ForeFlight Mobile in the App Store. You may be notified of an update
to ForeFlight Mobile via an update badge, push notification, or banner,
depending on your iOS device’s Notification settings.
NOTE: Not all updates to ForeFlight Mobile will contain firmware updates
for Stratus.
Once you have updated ForeFlight Mobile, you may apply the Stratus
firmware update, if one is available, from the Stratus Status page. If a
firmware update is available, the firmware version on Stratus Status page
will be followed by the text “Tap to Update.”
To apply the update, tap the firmware version number in the Stratus Status
page and follow the on-screen instructions. It may take several minutes
to update Stratus’s firmware. Do not power off your Stratus or iOS device
during a firmware update or close ForeFlight Mobile.
NOTE: You may need to reconnect to ForeFlight Mobile after your
Stratus’s firmware has been updated.
Stratus is an ADS-B In only product and does not satisfy the FAA’s 2020
ADS-B Out requirement.
Use of personal electronic devices while in-flight may pose a safety hazard.
Use of Stratus on an operating aircraft is subject to approval by the Pilot in
Position information provided by Stratus should be used for situational
awareness only and should not be used as your primary navigation source.
AHRS data provided by Stratus should be used for supplemental purposes
only and should not be used for IFR flying.
ADS-B weather information is provided within the United States only.
Weather information provided by Stratus is delayed and may not always be
available. Do not rely solely on the information provided by Stratus to make
tactical decisions.
Stratus does not replace the need for collision avoidance systems or see-andavoid procedures! Most aircraft are not currently ADS-B Out equipped and
therefore not detectable by Stratus.
Do not store Stratus in environments where temperatures exceed 45°C
(113°F) or are lower than -20°C (-4°F). Do not operate Stratus in environments
where temperatures exceed 35°C (95°F) or are lower than 0°C (32°F) Battery
performance will be negatively affected if these temperature thresholds are
Stratus contains a fan inside the battery compartment that will turn on if the
battery reaches a predetermined high temperature. The fan draws cool air
in through vents located on the front of the device and exhausts warm air
through vents located on the back. For this reason, it is important to position
the front of Stratus as close to the pilot as possible so that it can draw cool air
from the cabin.
To prevent permanent damage to the device, Stratus will automatically power
off if the battery reaches a temperature at which it is unsafe to operate.
Stratus contains a lithium battery. Do not disassemble the device. Do not
incinerate or puncture the device or the battery.
Ensure that disposal of Stratus is in accordance with local requirements for
the recycling of electronic appliances and batteries.
Check with current FAA rules before carrying device on checked luggage.
