How do Stratus portable receivers communicate with my iOS device?
Stratus portable receivers connect to your iOS device via a Wi-Fi network. Stratus portable receivers are not Bluetooth-compatible.
Can Stratus portable receivers be placed upside down, such as when mounting to the ceiling of the aircraft?
Yes, Stratus portable receivers can be placed upside down without causing any loss of AHRS accuracy or problems with Wi-Fi communication. This option is especially attractive in aircraft with limited dash space. If you are using the AHRS feature of ForeFlight Mobile, ensure that your receciver is mounted parallel to the aircraft’s centerline (that runs north and south) and the LEDs and Stratus logo are facing the back of the aircraft. Since the internal GPS antenna is located on the top of the receiver, you may see some GPS degradation. To remedy this problem, you can connect the receiver to an external GPS antenna. External GPS antennas for the Stratus 2 and 2S are available from Appareo.
Can I dim the Stratus portable receiver LEDs for flying at night?
Yes, you may dim or brighten the LEDs using the LED Brightness slider on the Stratus Status page within the ForeFlight Mobile app.
How do I register my Stratus portable receiver?
When you purchase a Stratus portable receiver from Appareo or Sporty’s, the unit will automatically be registered. No further action is required to register your receiver.
Why is my Stratus portable receiver’s fan constantly running?
The fan only runs when the receiver reaches a high temperature; the fan should not be on all the time. If your receiver’s fan frequently turns on, or you receive an overheat error, your mounting location is subjecting it to high heat. Refer to How can I optimize my Stratus portable receiver ADS-B reception?.
How will my Stratus portable receiver receive firmware updates?
Stratus portable receiver firmware updates will be available within ForeFlight Mobile. Updates to ForeFlight Mobile will be available via the Apple App Store. Watch a video with step-by-step instructions for updating your Stratus portable receiver firmware.
How can I optimize my Stratus portable receiver ADS-B reception?
ADS-B reception can vary greatly depending on the orientation of your Stratus portable receiver and its location in your aircraft. ADS-B is ground based, meaning the best mounting options provide an unobstructed view of the ground in your aircraft. See the table below for the three mounting options that may improve your Stratus portable receiver’s ADS-B reception. All mounting accessories can be purchased online at Appareo.
|Gel pad dash mount||Suction cup mount||External ADS-B antenna|
|Pilots flying aircraft with unheated windshields in areas where there is full ADS-B coverage.||Pilots who are not seeing continuous ADS-B coverage when flying in ADS-B fringe areas and those who want to mount their Stratus portable receiver off the glareshield. To test if the suction cup mount would improve your receiver’s ADS-B reception, open the Stratus Status page in ForeFlight Mobile while in flight and monitor the number of towers shown in the “Receiving From” field. Then rotate your receiver on its side and hold it to a window and see if the number of towers reported increases. Many pilots see dramatic improvement in ADS-B reception after moving their receiver to a side window of their aircraft.||Pilots who fly in areas with poor ADS-B coverage and those who want the flexibility to place their receiver virtually anywhere in their aircraft. Don’t worry if you can’t see the LEDs on Stratus. The same information is available on the Stratus Status page in ForeFlight Mobile.|

If the battery goes too long between charges, it can require service to repair.
My Stratus portable receiver isn’t holding a charge. Can I buy a new battery?
Yes, a Stratus portable receiver battery replacement kit is available to purchase from the Appareo webstore.
Compatible Apps and Devices
What apps do Stratus portable receivers work with?
Stratus portable receivers work exclusively with ForeFlight Mobile. Companies other than ForeFlight making claims that they “support” Stratus portable receivers are misleading. They are not endorsed or supported by Appareo, ForeFlight, or Sporty’s and therefore we cannot confirm or verify any unsupported app maker’s claim to deliver a safe and reliable experience.
What should I do if my Stratus portable receiver stops working properly after using an unsupported application?
Unsupported applications have been known to:
- display inaccurate or incomplete ADS-B information,
- display inaccurate flight parameters (e.g. AHRS information), and
- create a denial of service to Stratus functions.
Appareo and ForeFlight do not recommend using Stratus portable receivers with unsupported third party applications that have gained access to the Stratus portable receiver interface without support from Appareo. If you do use your receiver with an unapproved third party application, you can encounter unexpected performance with your receiver or your iPad.
To solve this error:
- Shut off and restart your iPad after using a Stratus portable receiver with the unsupported application and then reconnect to the Stratus Wi-Fi network.
- Launch ForeFlight to resume normal receiver operations.
- Do not activate the unsupported application while connected to the receiver, which would then require Steps 1 – 2 to restore normal operations.
Which iPad or iPhone devices are compatible with Stratus portable receivers?
Using the latest technologies recommended by ForeFlight Mobile will enhance your overall Stratus portable receiver experience. For the latest recommendations visit ForeFlight Mobile.
Due to the amount of data processing required to display ADS-B weather, we strongly recommend using an iPad 2 or newer. Stratus portable receivers are also compatible with the iPad mini, and the iPad Air (with the exception of the Stratus 1). We strongly recommend and iPhone 4 or newer or the third or fourth generation iPod touch.
Can more than one iOS device connect to a Stratus portable receiver?
Yes, all compatible iOS devices in the aircraft can be connected to the Stratus Wi-Fi network.
Do I need to buy the Stratus portable connection kit with Stratus ES or Stratus ESG?
You may continue to use your Stratus portable receiver independently, but purchasing the connection kit will allow you to take the Stratus portable receiver off the glare shield or window and stow it out of the way when using the transponder. The portable receiver will use the aircraft’s mounted antennas for excellent GPS and ADS-B reception, and will be supplied power from the transponder.
Do I need an external GPS antenna with Stratus 2 and 2S?
The external GPS antenna is an optional accessory for your Stratus 2 and Stratus 2S. Stratus 2 and 2S contain an internal GPS antenna that will be sufficient for many pilots. The GPS antenna, however, provides many more options for placing Stratus in your aircraft and resolves reception issues caused by heated windshields. An external GPS antenna can be purchased online.
Do Stratus portable receivers provide GPS location information?
Yes. Stratus portable receivers include a GPS/WAAS receiver and will provide GPS information to ForeFlight Mobile. Since Stratus portable receivers are battery operated and can operate for up to 8 hours, the receiver will keep a constant GPS signal and make that available to ForeFlight Mobile.
Do Stratus portable receivers provide GPS information for applications other than ForeFlight Mobile?
No, Stratus portable receivers can only provide GPS signals to ForeFlight Mobile.
Can I use Stratus ESG’s WAAS GPS signal to feed other avionics such as a navigator or emergency locator?
No, the WAAS GPS position is only available to the transponder for ADS-B out purposes, and, if connected, a Stratus portable ADS-B in receiver.
Why is my Stratus receiver is reporting poor GPS accuracy when connected to Stratus ESG?
A firmware update may be required for the Stratus receiver to ensure data is reported properly. If the Stratus firmware version is older than what is listed below, please perform an update using the instructions found here.
Stratus 2S: Version 1.1
Stratus 1S: Version 1.1
Stratus 2: Version 2.1
How do I prevent interference between my Stratus portable receiver’s external GPS antenna and other avionics?
When damaged, the optional external GPS antenna that works with Stratus portables may emit noise that could interfere with other on-board GPS receivers.
To prevent this, when handling the external GPS antenna, avoid pinching the cable or bending it near the antenna itself. If you suspect that your GPS antenna may be damaged and causing interference, disconnect the antenna from the receiver. If the interference stops, replace the GPS antenna.
NOTE: This applies only to the external GPS antenna; the GPS antenna located inside the Stratus portable is not susceptible to this issue.
Where can I buy Stratus portable receivers?
Where do you ship Stratus portable receivers?
Due to regulations on technology used in Stratus portable receivers, they may only be shipped to addresses within the United States.
Can I order Stratus portable receivers over the phone?
Yes, we would be happy to take your order over the phone if you are unable to place your order online. Please call +1-701-356-2200 between 8 AM and 5 PM CST, Monday through Friday.
What is the return policy for Stratus portable receivers?
Can I get traffic information from Stratus portable receivers?
Yes, Stratus 1 and Stratus 1S receive traffic on the 978 MHz (UAT) frequency. Stratus 2 and Stratus 2S receive traffic on both the 978 MHz and 1090 MHz (ES) frequencies.
The traffic you see on ForeFlight Mobile is only ADS-B traffic. ADS-B traffic only includes the air-to-air traffic received directly from another aircraft and traffic rebroadcast to your aircraft from an ADS-B ground tower. Air-to-air traffic reports are only reported from ADS-B Out equipped aircraft. You will only receive ADS-B traffic from a ground tower if two things are true: 1) your aircraft, or another one nearby you, is ADS-B equipped, and 2) you are in communication with an ADS-B ground tower. Coverage varies based on your location as shown in the ADS-B coverage map.
Remember, ADS-B traffic, even at its best, is not a complete picture of nearby traffic and is not a substitute for looking out the window when fulfilling your responsibility to see and avoid.
My aircraft is equipped with a Stratus portable receiver and an approved ADS-B out transponder. Why do I not see traffic information displaying on ForeFlight Mobile?
Specific settings may need to be adjusted on your transponder to properly trigger, receive, and display traffic information. Contact your certified avionics technician for more information on adjusting these settings. If you have Stratus 1 you will only receive single-band 978 MHz traffic.
Make sure that you are running the latest version of ForeFlight Mobile. Next, connect to your Stratus portable receiver and check on the Stratus Status page in ForeFlight to ensure that the device is running on the latest firmware version. Firmware upgrades are done from the Stratus Status page by tapping on the firmware version. Finally, ensure the Traffic layer is turned on in ForeFlight.
Why do I see a “ghost” aircraft mirroring me in ForeFlight Mobile while I am using my Stratus portable ADS-B receiver?
If your aircraft is not equipped with an ADS-B Out system, ATC can rebroadcast your Mode-C target to nearby ADS-B Out equipped aircraft. If you receive that transmission, it can cause your own aircraft to be displayed as a nearby target, usually slightly behind your actual position and +/- 100 to 200 feet in altitude.
The only way to remove the “ghost” target is to turn off the Traffic layer in ForeFlight Mobile. If you have ADS-B Out installed on your aircraft, ensure that you have the “Ownship ADS-B” option selected in ForeFlight Mobile. Click here for instructions on how to perform these tasks in ForeFlight Mobile or contact ForeFlight support for assistance.
What is ADS-B?
ADS-B, or Automatic Dependent Surveillance-Broadcast, replaces traditional radar with modernized subscription-free weather and traffic information received from ground stations and ADS-B Out equipped aircraft. ADS-B is the technology implemented by the FAA to provide surveillance and improved situational awareness to both pilots and air traffic controllers.
For more about ADS-B, visit the Stratus homepage.
What weather products are available from ADS-B?
Stratus portable receivers receive and transmit to ForeFlight Mobile CONUS NEXRAD, regional high-resolution NEXRAD, METARs, TAFs, TFRs, AIRMETs, SIGMETs, NOTAMs, pilot reports, and winds/temperature aloft. Each product is integrated with ForeFlight Mobile’s Airports and Maps features.
Do Stratus portable receivers replace XM weather?
No, the information provided by Stratus portable receivers and XM differ. XM Weather offers a wider array of information and more coverage. This table will help you compare and contrast Stratus portable receivers and XM and help you decide which in-flight product is right for you. Many pilots will find adequate ADS-B coverage within the areas they fly most frequently. Refer to the ADS-B Coverage Map to determine if there is coverage for your region.
Are there any subscription fees associated with ADS-B weather?
No, but Stratus portable receivers do require a current ForeFlight Mobile subscription. ForeFlight Mobile Pro subscribers will enjoy improved position accuracy when using a Stratus portable receiver as a GPS source.
Are there different types of ADS-B ground stations?
Yes, there are four different types of ADS-B ground stations: surface, low altitude, medium altitude, and high altitude. The FAA’s Aeronautical Information Manual, Table 7-1-2, helps compare each station type (Last updated: 4/4/14). The station type varies based on the ground station coverage where you are flying. Learn more information about ADS-B station types and how they interact with your Stratus portable receiver.
Do I need an external ADS-B antenna for Stratus portable receivers?
It depends. Most pilots will not require an external ADS-B antenna with Stratus portable receivers and can thus operate completely wire-free. Stratus portable receivers include a specially tuned, high-performance internal antenna that will get good reception in many aircraft. Some aircraft, however, may require a remote antenna due to signal attenuation caused by the aircraft type, altitude, and coverage. The position and mounting of the Stratus portable receiver will also impact ADS-B reception. If you find you need a remote antenna, you may purchase the external ADS-B antenna from Appareo’s Stratus accessory page. Please note that external GPS antennas are compatible with Stratus 2 and 2S only.
Does the Stratus portable receiver ADS-B LED turn on when it receives air-to-air ADS-B traffic?
The ADS-B LED on Stratus portable receivers is not activated by air-to-air ADS-B traffic; it is only activated when an ADS-B signal is received in the past three seconds from an ADS-B tower.
