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."

Michael R Adelman | 4/17/2017
Works as advertised with foreflight


Last year I purchased a skypro GPS 160 which sometimes would be dropped by my ipad. But most of the time it worked well. But I wanted to obtain current weather stations and w/o making my iPhone a hotspot, (iPad wasn't cellular) I was unable. Now I get current "everything" and the ADS-B IN worked great. Alerted me of a/c before I could see them (although this isn't a cure for looking for a/c).

Stratus 2S


Recently purchased the stratus 2S and have been pleased with its functions. The ability to see ADS/B traffic on my iPad before I can physically see it is an excellent SA builder. The accuracy of the WAAS GPS is spot on. Haven't had to use the wx and AHRS features too much but I'm sure they'll prove themselves very useful in due time. Overall I really like the stratus 2S and am happy I purchased it.

Awesome technology coupled with simplicity and ease of use!


I ordered my Stratus 2 after seeing a fellow pilot with one in the FBO that I fly out of in Lousiana. I did the research and realized this was an awesome piece to add to my flight bag. I've been flying with it for almost a year now, but I was hooked after the first day of using mine because of how simple it was to use and because of how it enhanced my situational awareness. My cross country flights have been less stressful and much more enjoyable just because of this added piece of ( essential ) equipment on board. Thanks Sporty's for always making my purchases easy, fast, and right on course!

Great product but has Achilles heel


99% of this product is terrific and it is a terrific value (in the context of aviation). It is very reliable. It has a long battery life, and the AHRS system gives great attitude reference provided that you firmly mount the unit somewhere. BUT... Guys - don't let the electrical engineers specify the external connectors. If you don't have one then contract with a mechanical engineer for this purpose and have that person design you a cannon plug connection. The early units used a micro USB which in my case vibrated its way loose in about 1 year and made the unit impossible to charge. The newer units have at least a better choice (USB Type C) but I will be surprised if it lasts two much longer. It really needs some type of positive locking connector - even a 4P4C phone jack would be an improvement over what it has.

Thank you for the review. We've had great success with the reinforced USB Type-C connector on the Stratus 1S and 2S. These units have been in service for almost 2 years and we've had terrific durability results.

GPS Technology at its BEST!


The Stratus 2 w/ a Mini iPad is a great combination for enhanced safety in General Aviation. I've had the system for several years now, and the added value to Alaska flying is unquestionable. I fly in an area where many of the airports have no navigational equipment, nor weather reporting stations, ... the Stratus 2 takes care of the voids in a high tech fashion. The synthetic vision really stands out when flying near mountains and also the shorelines, rivers, obstacles, etc.. Flying is fun, this makes it even better!

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:
We are using this equipment in a hospital; multiple patient usage. What do you recommend for cleaning between use?
A shopper on Nov 4, 2016
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.
Can this unit pair and run 2 iPads at the same time?
A shopper on Aug 3, 2016
BEST ANSWER: I usually run my mini iPad along with my iPhone on the yoke mount. Great combination, I use the iPad for mainly glass panel nav and the iPhone for airport info and weather info. iPhone info slightly less limited than the iPad, but still works like a charm. I also pack an extra iPad for back up.
Will Stratus work in Canada?
Alex G on Jan 8, 2017
BEST ANSWER: The GPS and the AHRS will work in Canada, so you'd have moving map and backup attitude. ADS-B traffic works but is limited in Canada. ADS-B weather does not work in Canada.
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.
I use jeppesen don't use forflight, can this app still work?
Cynthia C on Dec 19, 2016
BEST ANSWER: Appareo Stratus and Foreflight are essentially made for each other and only each's a shame that they don't open source it for better flexibility for ADS-B transceiver/Receiver options like other EFB and/or ADS-B manufacturers do....there is another EFB company that states on their website that their product will work with Stratus, but I believe that it is only with certain models of Stratus, and that there are glitches that interfere with smooth operation.
Does it come with a mount?
A shopper on Jul 6, 2016
BEST ANSWER: Yes it does - it includes a suction cup mount for use on a side window.
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.
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 G Force Suction Mount work with Stratus? RAM mount fell off the side window twice on my last trip. RAM mount seems weaker than when we first got it 2 years ago.
Doug O on Dec 29, 2016
BEST ANSWER: it has worked great for me so far. I have mounted in several places and it has stayed stuck on every bumpy cross country flight on my cessna 150
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 work in Hawaii?
A shopper on Sep 27, 2016
BEST ANSWER: Yes. It was recently purchased, and the Stratus 2S is being used in a Beechcraft BE-58, Honolulu International Airport. Very accurate. Excellent display. Good supplement to any aircraft.
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
does it have the ability to couple and fly an ILS approach?
dallin152 on Apr 26, 2017
BEST ANSWER: The Stratus does not have the ability to couple and fly an approach.
What about an extra battery or battery backup for this?
Jeff Annis on Apr 24, 2017
BEST ANSWER: This is not an extra or back battery for the Stratus. The unit is cable of being charged or power by a usb port while in flight.
Can the unit be mounted upside down using the suction cup, I fly an L-19 with skylight, and work?
Richard W on Apr 16, 2017
BEST ANSWER: Yes, just make sure the lights are pointed towards the tail. You mail also need to calibrate the unit with foreflight. See our videos at
Did It cover Saudi Arabia?
A shopper on Apr 11, 2017
BEST ANSWER: The GPS will work world wide. The Weather and traffic is only available in the United States.
Does this work with FlyQ EFB?
A shopper on Apr 4, 2017
BEST ANSWER: The Stratus 2s is exclusive for Foreflight.
Will there be a NEW version of the 2S to be released in the near future or will the company offer firmware updates to get you the latest and greatest features? And, if so, is there a published price for a firmware upgrade?
Barry G on Mar 28, 2017
BEST ANSWER: We are unaware of a new version of the Stratus. The firmware are contained in Foreflight and are included in the subscription price for Foreflight.
Does the stratus come with the suction mount?
A shopper on Mar 26, 2017
BEST ANSWER: Yes it does.
How do i configure this to my aircraft call sign for other aircraft ot identify me? Is there a nav. database for India?
Lalljee A on Mar 13, 2017
BEST ANSWER: You can not configure this for the aircraft call sign. The GPS will work world wide but the weather and traffic data is only available in the USA.
Is this antenna compatible with the Garmin G5 electronic flight instrument also? The Garmin site says that the instrument needs a certified WAAS GPS source.
jaytferg on Mar 7, 2017
BEST ANSWER: No it is not compatible. The WAAS GPS source for the G5 must be and installed unit. I.E the garmin 430W or 530W or other WAAS gps.
Is sgtratus 2 ads- receiver in and out capable?
A shopper on Feb 9, 2017
BEST ANSWER: The Stratus 2S ADS-B receiver is only ADS-B in. For the complete solution you would also need the Stratus ESG Transponder.
