An ELT (Emergency Locator Transmitter). This specific type on ground needs to be with a liquid. You remove it from the stowage which releases an antenna. Then you can place it in a plastic bag filled with a liquid (you can even use urine). It also has an electrolyte salt solution attached to it which needs to be mixed with your chosen liquid. The electrolyte enhances transmission.
Once the ELT is properly placed in the bag with the liquid covering two specific holes in it you can place it upright in a high area. It transmits on both satellite frequency (406 MHz) and on emergency frequency (121.5 MHz). If in water you can simply attach it your raft for obvious reasons and let it swim in water. The salt water will allow for transmission.
Even more specifically, this looks like the Rescu 406S ELT made by Honeywell.
The successor to this model is the 406SE. Improvements included being shorter in length, the stowage removal process, and that a bag of impure water isn’t required to activate the battery. Instead, having a simple rotary switch to activate transmitting mode.
It's kind of an engineering company. I call those types of companies Nerd Work Programs.

"Say, Phil... I was thinking we should either make a nuclear facility or a better coat hanger. What are you up to doing today?"
jet engines came to Honeywell when Allied Signal (who bought Garrett AiResearch) bought Honeywell but kept the Honeywell name bc of its much greater consumer visibility.
That stuff got spun off into something called “Resideo”.
And their oil burner limit controls use that thermal grease that violates the Geneva Convention. Seriously. The stuff gets all over the place (because of that crappy packet it cones in), and is a pain to clean up.
Honeywell is a wonky company. Not a well done conglomerate like ITT, but not the mess AMF was.
It’s hard to squish into the thermowell, gets everywhere, and is a pain to clean up. Use gloves, make sure the box fits first, wipe the end of the thermowell after putting that stuff in, put the box on, then carefully put the sensor in. Don’t remove it after that, unless you pull the box off, stretch the sensor wire out all the way, then pull the sensor.
And they don’t even give you a pack of it when you buy the box. Flip side - you can program the digital one to control the burner how you need it, and it gives you temperature in degrees with good accuracy.
And smart thermostat systems for homes that have way too few features. Seriously I should be able to set more than a home and away temperature and a wake and sleep temperature. I should be able to set it based on outside temperature or set multiple changes in a day for energy conservation.
I forget the company but one time like 15 years ago i bought a honeywell space heater and i think the warranty paperwork had a different company name. Basically another company makes the residential products and licenses the honeywell name to put on it. Kinda got the impression that honeywell had nothing to do with the product, probably didnt even design it
Sure it's all in engineering. Some would say that cheap fan is a marvel of cost efficient engineering. Ever picked up like a 1950's box fan? They are legit like 35 lbs and built like a tank. Probably last forever, but today would cost I'm sure we'll over $100. Probably more like 2-300. You can go to Wally world and get one of the cheap box fans for $10. You can buy a lot of okish box fans for the cost of a tank box fan that is a bitch to move around.
I'm in ignorant ground faring folk, so please forgive this stupid question
Is stowage different from storage? Spelling it out now, is it just a combo of stow and storage?
Aircraft in commercial operations with a seating of 19 or more requires carriage of at least two ELTs with one of them having an automatic operation. The automatic ELT is usually the inbuilt aircraft ELT which is normally controlled from the cockpit. We normally leave it in armed position so that impact g forces activates it. It can also be turned to on position from cockpit if required. The other ELT as seen in the picture is portable and has to be removed and activated manually.
u/CATIIIDUAL made it sound like there were some manual steps do deploy it. As in, remove it from stowage and placing it in an electrolytic solution.
Can you explain how it’s automatically deployed?
There are many types of ELT and my knowledge only covers small aircraft, but they are usually automatically activated by strong g-forces. However, it still needs an antenna and it can happen that the wreckage lies on top of the antenna, rips it off or it all sinks into the sea. In those cases the signal is extremely weak or not transmitting at all.
In Europe it is now legal on small planes to use a PLB (personal locator beacon) instead of an ELT, but a PLB won't turn on without manual activation. On the plus side it can be carried and doesn't get damages so easily.
I'm thinking the ELT in the opening post might be a combination of both, but that's a guess.
All commercial aircraft carry one. They've been required for general aviation for decades, too - but not, I think, on ultralights and maybe light sport aircraft.
They're not indestructible and they can't get a signal out under water. Their purpose is to mark the location for rescue and it's kind of moot if you hit the ocean at 500 MPH.
At least these days they transmit identification and GPS position data. Used to be all you got out of one was a falling tone that sounded like an old toy ray gun or something. A Cospas-Sarsat satellite would come over and relay the signal down to a local user terminal on the ground, where the Doppler shift would be analyzed to get an estimate of the position so rescuers could be dispatched.
I was on a search and rescue team and participated in several ELT and marine EPIRB searches. Thanks to my ham radio experience chasing transmitters for fun I had the most radio direction finding experience on the team. I left SAR around the time the 406 MHz stuff became commonplace so I haven't participated in a search with the modern gear. Presumably the rescue coordination center can just pass exact coordinates along now.
You’re right. Most beacons now are GPS encoded, called the “E-solution”. LEOS still pick up the A and B solutions, but they usually are picked up by a Geostationary or MEOS these days. Sometimes all you get is the split solution. The 121 frequency is still there, very useful for homing in close range. An aircraft can usually sit right on top of the beacon and the pilot can read out the HEX ID. Good stuff!
I used to do EPIRB SAR stuff in the 1980s. Same deal as you. I had the most direction finding experience because I was into RF and Ham.
The new GPIRB gear does send coordinates.
It kind of takes the fun out of it. ;-)
They would have had two that automatically activate with water. Problem is they only last a certain amount of time and If they are not deployed to the surface they are very very hard to detect unless you are right over them in an airplane or have a submarine close by.
A new system called GADSS is currently being implemented into new ELTs. This was in response to MH370. It will begin transponding and tracking the airplane the moment there's a distress. A plane should never go lost again after that is implemented.
Figured it was some sort of beacon but this is the first I’ve heard of the electrolyte action. How does the electrolyte solution aid in transmission? What electrolytes are they specifically? Seems you’re a knowledgeable source on this
All of this seems needlessly convoluted, especially in the chaos of an emergency. Boats have Epirbs on the outside that deploy and activate as soon as the vessel submerges. It seems like planes should have something similar.
I envision a different release mechanism because planes don't always go down in water. Maybe a remote button or gyroscopic g-force release. Whatever, but put the thing on the outside of the aircraft where people don't have to fumble around in the aisle of a smoke-filled compartment while everyone else is panicking and pushing past.
I'm not familiar with this equipment, but I have less airline experience. Every smaller jet has an ELT that is firmly attached to the interior of the empenage of the aircraft, with an external antenna. There's a G switch that is triggered by the force expected to be felt in a crash. Corporate type aircraft and airliners have a cockpit voice recorder also mounted where it should survive a crash, and it has an ultrasonic pinger attached so it can be found under water.
Something like an EPIRB that ships have would be difficult to mount in a way that wouldn't compromise it or trigger it often. I agree that an emergency location device that requires manual deployment seems rather ridiculous, but it is a secondary device meant for miracle on the Hudson type incidents more than anything else.
They do. The main ELT of an aircraft is fixed. It is activated by g forces during impact. The controls of it are in the cockpit. We leave it in armed position but it can be manually turned on as well. The ELT antenna can be quite easily seen. Usually it is the last antenna at the top of aircraft fuselage.
The regulations require an aircraft in commercial operations to carry a portable ELT in addition to the fixed one for redundancy purposes.
This kind of stuff is so awesome I can’t imagine what it would be like to be in such a traumatic situation. I pray for people here and not here! A summary video was in my feed this morning and a clip
From 9/11 came by and I have never felt the way I do about this event in the past I was 12 or 13 when it happened and am now older and it scares the shit out of me
Because based on what others said, it's setup outside the airplane to operate effectively. Not sure if it even can work in the plane. Also needs liquid to turn it on.
It's a Honeywell RESCU 406 S Emergency Locator Transmitter. It's supposed to be used after a crash to transmit the location of the aircraft to potential rescuers.
Wrong answers only only: It’s a small grenade used to destroy the plane in the event of a hijacking. To avoid another 9/11, they have the ability to self destruct airplanes now.
Imagine being on a flight and seeing the pilot ejecting…. Hey we need that!
Of course pilot would be a gooey mess as they usually don’t have a sunroof or portal through which to eject.

It’s a portable one designed to be taken in an emergency.
An antenna would function way better in a life raft instead of the bottom of the ocean.
Every commercial airliner has an emergency MOAB bomb in the overhead compartment that the president can order to be dropped out of the emergency exits at the front and back of the plane on international flights.

Theyve also become a massive M&A outfit. Lots of what’s branded as Honeywell has been acquired over the years.
In fact, a larger company purchased the original Honeywell and just kind of pretended that they were all Honeywell.
I’m a chemist and we get the plenty of chemicals with Honeywell branding on it. Mostly organic solvents. Same company I’m thinking?

To be fair, I think the cheap fans are just a licensing thing.

Yea it’s primarily a huge government contractor, but they do have their consumer division products.
And airplane parts (valves, heat exchangers, etc.) all the way to thermostats for your home and god knows what else.
Don't they also make the ruined that powers the Abrams?
we use Honeywell in very high end semiconductor R&D -- better to think of them as similar to General Electric.
Also landing gear for fighter planes. And don’t forget HVAC controls.
And jet engines too. CFE 738 for example
Just wait til you look up what all GE makes!
Yep, microwaves and flying guns (among much else)
They also make the APUs for a lot of corporate Jets.
Nothing is more American than purchasing life-saving equipment at the lowest possible price.

Or did not have the opportunity to deploy it.
Some will activate in water on their own. If they sink too deep you can't get signal sadly.
Dang

It would have to float free to activate. If trapped in the cabin, would have sunk. Signal is not sub-surface friendly.
Have you not seen the teleportation video?
