Made for ForeFlight

Stratus™ is the simple-to-use, pocket-sized, wireless receiver that transforms your iPad into the ultimate flight tool. Get subscription-free weather, GPS information, ADS-B traffic and backup attitude – all integrated with ForeFlight Mobile. The new Stratus 2S offers additional features and even better performance, but with the same pilot-friendly design that has made Stratus the best-selling ADS-B receiver in aviation.

Subscription-free in-flight weather

In-flight weatherYou can view in-flight weather on your iPad, including NEXRAD radar, METARs, TAFs, TFRs, AIRMETs, SIGMETs, NOTAMs and more. It's updated every 5-10 minutes and there are no subscription fees – ever. Stratus Replay allows you to turn off the iPad screen in flight and save battery; when you turn the screen on again, Stratus will automatically send all the weather information you missed. Also includes animated radar, so you can monitor trends in a storm. Just tap the play button.

Stunning synthetic vision display

Synthetic visionForeFlight's new Synthetic Vision feature rewrites the book on situational awareness. With luminous terrain, night sky view, hands-free declutter, and a brilliant obstacle awareness system, ForeFlight with Synthetic Vision will forever change the way you fly. With Stratus 2S, ForeFlight's synthetic vision really comes alive. The built-in AHRS drives a super responsive pitch and bank instrument in the center of the Synthetic Vision view. In an emergency situation, you’ve got a backup glass cockpit on your iPad.

Dual band ADS-B traffic

TrafficStratus 2S includes a dual band (978 MHz and 1090 MHz) ADS-B receiver so it can display traffic information right on the ForeFlight Maps page. See relative altitude, climb/descent rate and projected track. Picks up all aircraft equipped with ADS-B Out as well as some aircraft equipped with Mode C transponders. Note: ADS-B traffic is limited unless your aircraft has ADS-B Out installed in the panel.

WAAS GPS Powers track up and terrain

TerrainWith the built-in WAAS GPS receiver, Stratus allows you to view moving maps, track up displays and high resolution terrain maps in ForeFlight. The smart GPS locks on fast and typically provides 1 meter accuracy. Replaces the need for a separate GPS receiver--Stratus has it all!

Built-in AHRS for backup attitude

Built-in AHRSStratus includes a complete Attitude Heading Reference System (AHRS) for backup attitude information in the cockpit. It aligns itself automatically, so you can just turn it on and fly. Now you can view a backup attitude indicator, GPS groundspeed and altitude on your iPad--in a beautiful split screen mode right in ForeFlight. (Not to be used for primary reference.)

Automatic flight data recorder

Flight data recorderStratus is the first ADS-B receiver to offer a complete flight data recorder system. When this is enabled, Stratus automatically records your flight--complete with GPS position, altitude speed and attitude. Flight logs are saved in ForeFlight, and can be viewed online, in Google Earth or in the CloudAhoy app. Ideal for proficiency flights and CFIs.

Pressure altitude sensor

AltitudeWith its built-in barometric pressure sensor, Stratus 2S allows ForeFlight to display both pressure altitude and GPS altitude. Plus, ForeFlight’s automatic Cabin Pressure Advisor alerts you when you might need oxygen by flashing a message anytime cabin altitude exceeds 12,000 or 25,000 ft.

The Stratus Platform

Seamless integration with ForeFlight mobile

ForeFlight integrationStratus is the only ADS-B receiver that works with ForeFlight, aviation’s most popular app. That’s because Stratus was designed from the ground up to integrate with the app, so you can view complete status information right from the moving map page. Stratus simply works the right way.

Works with Apple watch

Apple WatchWith a Stratus on board and connected to iPhone, ADS-B weather is delivered right to ForeFlight for Apple Watch. Easily view current METARs for airports in your recents and favorites lists. A customizable dashboard of flight instruments is also available, which helps you keep track of information like ETE, ETA, distance to destination, track, ground speed, GPS altitude, and more.

Designed to work with the Stratus ESG transponder

ADS-B outGet a complete traffic picture when you add Stratus ESG - the only ADS-B Out transponder made specifically for Stratus. This all-in-one solution, which includes a built-in WAAS GPS, meets the 2020 FAA mandate, and offers improved reception and full-time power for your Stratus portable. Certification planned for early 2016.

From the Press

"The standby instrument presentations on a tablet (at least an iPad and ForeFlight) have reached a level of sophistication that, in my opinion, allow a high-performance single-engine piston airplane to be safely flown to VFR conditions in an emergency. It's far easier than partial panel flight using a turn coordinator."

- Rick Durden, The Aviation Consumer

"We flew with the Stratus 2S portable ADS-B receiver for over a year to see how it would hold up. It proved solidly reliable in virtually all weather."

Brian Knight | 11/22/2016
Worth it!


Every time someone sees my Foreflight and the Stratus is on, I think I've sold both items. I bought this as a present and backup after I passed my instrument ride in May. Flying in a busy airspace like DFW, it's invaluable, but also in the rural areas, if they have ADSB, you can see their call sign and ask them there intentions.
The stratus makes foreflight function just like you were on the ground. You can instantly get METARS, favorable winds, and see yourself on the approach chart as you fly the approach.
If you don't have XM weather, this is the solution. I compare the two, which are frequently subtly different.
I could go on and it. You won't regret it.

for your GA aircraft this should be it. I use it with my iPad in rental aircraft and it's wonderful. Stratus provides me with weather, ADS-B in, and great situational awareness when I couple it with ForeFlight. This is a must-have.

Equipment failure


I was borrowing a plane to make some trips, and on the 4th leg the vacuum pump just quit. Fortunately I had the stratus 2 antenna coupled with foreflight pro, I was able to complete the trip using the synthetic vision. It was critical to maintain course because I was flying near a TFR, and I didn't want my own air show.

Great device


Very easy to use and the data displayed is incredible. Battery lasts for a long time and you can put it almost anywhere… Just so it's in the direction of flight.

Nice unit but what's up with the case?


I received my new 2s today, as I upgraded from the Stratus generation 1, so this is a very nice improvement. The white case, the smaller and more solid feeling package, etc. seems very nice. I only rated the categories that I could since I've only had this one day, but as long as it performs like the generation 1, I'm sure I'll be happy (albeit a little expensive). However, the reason for my review is that the case, which appears totally custom designed for this unit and it's accessories, does not fit the RAM mount! There's an area in the case for the mount, and it has an indented cylinder presumably for the RAM suction cup, but it won't fit. No matter how I puzzle the RAM mount, it will not nicely fit in the case, and to keep it in the case, you need to smush it in there which will probably ruin the RAM suction cup. Any way that you place the mount in the designated spot, you have to subject the mount to deformation of some sort. For almost a thousand bucks and what appears to be a totally tricked out custom case, I am disappointed in the "misfit" of this item. Anyone else with the same problem?

"Damaged" Product


Received the Stratus quickly from Sporty's Pilot Shop. I opened the package......everything was packaged just fine except for the Stratus unit itself. When I pulled the unit out of its pocket, I noticed the unit had dirt on it and after examining it more closely, I noticed many small scuffs all over it and also a red "crayon-like" marking on the side. I called Sporty's customer service line under the assumption that the Stratus unit I received was either used or "refurbished" (not what I had paid for or expected). The associate on the line was friendly to me, but when I told her that I wanted to return the product due to it being scuffed and possibly "used", she quickly informed me that this was a normal occurrence and that the product should work just fine, regardless of its exterior condition. Apparently, other consumers had received their Stratus from the manufacturer with similar "scuff marks" on it and the customer service associate informed me that the padded case the unit came in was the cause of these scuff marks. I find this extremely hard to believe, as the interior of the case had no sharp edges and the Stratus unit fit snugly in its designated spot with absolutely no free movement. I tried repeatedly to plead my case with the customer service associate, but she seemed to be more concerned with defending the manufacturer than with actually listening to my concern. She told me that the unit should work totally fine as advertised regardless of the scuffs and scratches on its exterior. To this argument, I replied with the example of a customer going to buy a "new" car from a dealer, only to discover that their $40,000 brand new car had scratches and scuffs on the paint. I asked her how she would feel if the salesperson told her: "Well, the car should run totally fine....we have a lot of new cars come from the manufacturer with these types of exterior issues". I was met with a reply of silence. Bottom line: I paid almost $1,000 for this product and I do not believe it is unreasonable to expect it to be in pristine, "brand new" condition when it arrives from the manufacturer. I will go ahead and use the product under the expectation that it will work as advertised, BUT if any Sporty's employee is reading this review, PLEASE NOTIFY THE MANUFACTURER and tell them that this is not an acceptable business practice.

Will this work on an original iPad or do I need a newer one?
Terry D on Jul 6, 2016
BEST ANSWER: Gen 1 iPad 16 gig mini w/cellular - no problems (cellular not needed or running when connected to Stratus 2
There is a note that says " Note: ADS-B traffic is limited unless your aircraft has ADS-B Out installed in the panel." What are these limitations? I'm purchasing to use in rental aircraft that are not likely to have ADS-B OUT
Don H on Jul 16, 2016
BEST ANSWER: Here's a good summary of the ADS-B traffic issue:
Can this unit pair and run 2 iPads at the same time?
A shopper on Aug 3, 2016
BEST ANSWER: Yes. It puts out a wifi signal, and should connect to as many units that are in the area.
Are the external antennas for the 2s required? How well does it work without them?
Greg M on Aug 21, 2016
BEST ANSWER: I mounted mine behind the panel, so I used the external GPS antenna and hooked the ADS antenna up to an unused belly mounted transponder antenna. It all works excellent. I have many friends that mount their 2s on the on top of the glare shield without external antennas and they say it works perfectly too, although the ADS doesn't pick up as many stations.
Will it charge ok from a 28V DC cigarette lighter connection using the usb cable? Or is it only 12 v tolerant?
Paul B on Aug 29, 2016
BEST ANSWER: I have never had to charge in flight. The battery is good for at least 6-7 hours. It has a USB charging cord so with a suitable cigarette lighter adapter, it should charge.

My aircraft is 24 volt and I use dual amperage (10 amp/ 21 amp adapter) to charge my I pad if necessary and works well. I found the adapter at Amazon for a couple of dollars but I believe Sportys would have something comporable. To be sure, I would call Stratus and pose the question. Best from the horses mouth.
Good luck. Best device I ever purchased.
How much memory on iipad is needed to run forefight mobile ?
Curtis N on Jul 28, 2016
BEST ANSWER: AMAP. Depends on how you fly.
If you stay within a couple states...less. On a 16gig foreflight dedicated iPad mini - flying about SoCal, Colorado, Idaho, Wyo, UT, NMex, AZ, there's still plenty room for all that is needed including FARs, approaches, etc..

Some music, photos etc too.
Does this provide real time weather to Foreflight while in flight?
John L on Sep 29, 2016
BEST ANSWER: The short answer is "no". I bought mine to use as a strategtic tool for a VFR flight from Connecticut to Alabama and back. At times it seemed real time but this was due to the nature of the pop up thunderstorms which "popped up" as the term implies, but then just stayed in one place as opposed to moving rapidly as they do in the northeast. That said, it was a great tool to have to help decide when it was time to get on the ground as every afternoon it definitely got tricky. For real time tactical information you would need weather radar or a Stormscope as the info on the Stratus could be many minutes old by the time it is displayed for the first time.
Let me get this straight. Stratus II will give me pitch, bank, air speed, altitude, an HSI, synthetic vision, weather, and traffic (in) on my IPad as long as the batteries last for $900?
Darrell S on Oct 25, 2016
BEST ANSWER: Yeah, you got that right. It's good for about 7 hours of flight time on battery power alone. If you plug in to a USB cigarrette lighter adapter it's good indefinitely. You may lose the weather and traffic links on occasion if there are no towers availble within line of sight but it works well in general. I'm running with 2 Ipads with Foreflight and get solid nav data. Have even flown several practice approaches stricly using the Stratus GPS data and it will put you right over the runway. The attitude data can be a little flaky. Not rock solid, but good enough to save your bacon in a no gyro situation.
Will this work with iPhone 6?
Patrick. M on Aug 31, 2016
BEST ANSWER: It works with my IPhone 6, my IPad and my instructors droid cell which runs a different software. I haven't had any problems.
how well does it work for IFR flight? also, where does a person go to get an external antenna and will the system charge off of one of those reserve battery backup chargers?
A shopper on Oct 9, 2016
BEST ANSWER: You sure can fly IFR. I've litterally flown coast to coast with more than a few hours IMC running on the Stratus with Forelight as my only charting info. Better nav than my certified on-board GPS. Certainly esier to use. I got a little USB power adapter for the cigarrette lighter port for power. One line feeds the Stratus and the other the Ipad. Have flown 9 hour days with no problems. I se no need for an external antenna. As long as the Stratus has a good view of the sky it seems rock solid.
Is the update rate slow? If I am using this for GPS guidance with Foreflight and will it be slow to update on my iPad Pro. I have used a cellular signal and that is too slow.
Brett F on Aug 29, 2016
BEST ANSWER: Brett, the Stratus 2S receiver is excellent for VFR use and it is extremely accurate and fast. I've never noticed any lag time as far as GPS position goes. Also, the backup AHRS system and synthetic vision is excellent and extremely responsive. I'd highly recommend buying it. I also use it with iPad pro... Good luck...pedro
Does the stratu have synthetic vision?
A shopper on Oct 18, 2016
BEST ANSWER: The Stratus 2 does not in itself offer synthetic vision. It provides the necessary feed to ForeFlight Pro that gives you synthetic vision. You have to have ForeFlight pro and not the lesser version to get synthetic vision. The Stratus provides ADS/B reception on both channels as well as GPS WAAS,attitude output to ForeFlight pro, and a number of other items to Fore Flight, but only ForeFlight pro gives you synthetic vision when using the Stratus 2 as the feed.
will this unit work with the latest Ipad mini 4 ?
dave c on Aug 29, 2016
Will stratus work with iPad mini without any problems if I also have Garmin gdl39 in use in same aircraft?
A shopper on Jul 27, 2016
BEST ANSWER: I would think that as long as you have Wi-Fi on your i-Pad mini and you get the Foreflight app / subscription, then it should work. I use a regular i-Pad and absolutely love the Stratus . I had the stratus 1 for 3-4 years, but it got to where it would not pick up any of the ground antennas and thus would not give me weather/storm radar on the i-Pad. The Stratus 2 is working great. Hope this helps
Will it work with iFly?
Pete E on Nov 30, 2016
BEST ANSWER: No, only ForeFlight at this time.
Does this work with the Garmin Pilot?
A shopper on Nov 30, 2016
BEST ANSWER: No, only ForeFlight at this time.
Does it come with an external antenna? I understand it can be mounted remotely (glove box of my Baron) with the antenna on the glare shield and have the radio shop hardline the power to it.
Darrell S on Nov 29, 2016
will stratus 2s work in south Africa?
Nikola P on Nov 28, 2016
BEST ANSWER: The GPS and AHRS will work, so you'll have moving map and backup attitude. The ADS-B traffic will work, but it will be spotty - you'll only see other airplanes with ADS-B Out installed. The ADS-B weather will not work - that's limited to the US only.
Does Stratus only work with Foreflight? Would it work with other programs such as Garmin Pilot?
A shopper on Nov 18, 2016
BEST ANSWER: Only ForeFlight.
Does stratus 2 s show lighting?
A shopper on Nov 17, 2016
BEST ANSWER: No, lightning is not transmitted via ADS-B at this time, but it's coming sometime in late 2017 or early 2018.
I have an iPad mini without cellular. Will it work?
Dominic C on Nov 16, 2016
BEST ANSWER: Yes it will - no problem.
Works with iPhone 7 plus?
Julian P on Nov 14, 2016
BEST ANSWER: Yes it does.
Does the Stratus 2s come with a warranty?
Rocky B on Nov 6, 2016
BEST ANSWER: Yes, it has a 1 year manufacturer warranty.
Can it be use for International flights?
A shopper on Nov 1, 2016
BEST ANSWER: The GPS and AHRS are self-contained, so they work anywhere in the world. That means you'll have attitude and moving map. The traffic is limited outside the US, so you'll only see other airplanes that are equipped with ADS-B Out. Weather only works in the US at this time.
I am planning to fly in Europe. Which features will work in Europe and which ones won't?
Aviator on Oct 24, 2016
BEST ANSWER: The GPS and AHRS will both work, so moving map and backup attitude. The traffic will work but only ADS-B Out equipped airplanes will show up. The weather will not work in Europe.
Will the Stratus 2S support the FAA's planned updates to FIS-B capabilities? The new weather products to become available via FIS-B in 2017 include information on lightning strikes, cloud tops, icing (current and forecast), and turbulence. The FAA is also studying uplinking one-minute automated weather observation station (AWOS) observations or center weather advisory (CWA) and graphical airmet (G-Airmet) products.
Collin A on Oct 18, 2016
BEST ANSWER: Yes, we plan to support all the new weather products when they become available.
How may get a digital copy of my stratus 2s operating manual?
Thomas J on Oct 14, 2016
Does this particular model work with the synthetic vision of ForeFlight to give attitude information? I've noticed there are two of the same Stratus; one being $200 more that says for ForeFlight Pro Plus. Wondering if the cheaper of the two still gives attitude information?
Justin R on Oct 13, 2016
BEST ANSWER: This will do SV. The other one simply bundles a ForeFlight subscription with it.
Is there a Bluetooth option for the data transfer? We have Wifi in our plane (that automatically quits getting data below 10k) and I would like to be connected to our WiFi and the Stratus.
A shopper on Oct 8, 2016
BEST ANSWER: It is only Wifi unfortunately.
Would stratus 2s work in Brazil?
Apolo on Oct 6, 2016
BEST ANSWER: The GPS and AHRS (for moving map position and backup attitude) will work in Brazil. Traffic will work partially, but the reception will be quite spotty. ADS-B weather will not work anywhere outside the US.
