How The Emergency Locator Transmitter Works In Plane?

There are companies that manufacture the design and all sensor types. Select Controls Inc provides the acceleration, impact, disturbance and tilt switches. They have the complete and independent engineering tool to cater to all client’s needs. They specialize in rapid prototyping of custom designs for unique applications. The company has many sensor products of different applications, including emergency locating transmitters.

What’s with Emergency Locator Transmitter?

Emergency locator transmitters (ELT) are essential pieces of equipment mounted in the plane. This device activates upon impact or manual use of the remote switch. This can be a control panel indicator in the cockpit. Most of the times its activation triggers an audio alert and send GPS position for search and rescue. This device is compact and kept on board for the safety of pilot, passengers, and crew.

How It Works?

The ELT sends out an automatic emergency alert beacon in the event of a crash or other emergency. This will help in the search and rescue crews to locate the craft. The model that can broadcast at 121.5 MHz or 406 MHz emergency locator beacon is the ideal types. The ELTs with a rod antenna works with your plane and normal route. There are also personal locator beacon types in the market. These are compact devices that carry on a lanyard which are usually worn by an individual. Having this device will help the rescue workers to find you after the crashed plane. This useful device will keep you safe, even in the most difficult types of situations. Most models will float on water and include integrated GPS devices for added safety.

The Ideal ELTs

Getting the ideal ELTS is best for aviation use. It is vital to make sure the plane is properly equipped with the latest models of ELT. Mount this device in the airplane to fly strong and safe. It is important to inspect this every once in a while. Replace the battery after one hour of continuous use, or after reaching 50 percent of its useful life. Test your 121.5 MHz ELT switching it on and listening on the frequency. This is to make sure that you are using a functional device before on-boarding.

The Proper Testing

Emergency locator transmitters are usually small in size and battery-powered device. This will broadcast a distinct sound on a dedicated emergency frequency. The newer models broadcast on 406 MHz. This will listen for signals captured by satellites and then sent to a command center. Test the device to ensure that the system will work properly. Begin by transmitting signals and then someone must be listening. Accelerometers will activate the emergency signal once a certain force threshold is reached. The newer models are much more reliable. This works more than 80 percent of the time and sends a signal that is much easier to pinpoint. A unit with GPS is ideal in determining your position can even more exactly.
