Emergency Locator Transmitters (ELTs) are radio beacons that are supplied on board aircraft and utilized in the event of a crash or other unprecedented incident. There are two main types of ELTs in service, those of which are the 406 MHz ELT and the 121.5 MHz ELT. To better understand the function of these ELT types, this blog will outline the purpose and function of ELTs.

A pilot’s main threat to a safe, smooth flight is turbulence moving the plane around. Air travel relies on the movement of air in atmospheric jet streams, which can be difficult for pilots and air control centers to track as they are invisible and can travel in any direction. In general, jet streams form in long, horizontal waves up to a thousand miles long, allowing pilots to save fuel by riding the current in a similar fashion to surfers riding a wave.  However, danger presents itself when jet streams traveling in multiple directions converge, forming turbulence.         

For the forward movement of an engine, the reciprocating motion of a piston must be converted into the rotation of the crankshaft. To perform this particular task, you need a connecting rod. A connecting rod is an integral part of the engine, forming the connection between the piston and crankshaft.
