Personal Locator Beacons (PLBs) are becoming cheaper and more reliable.  Why would a pilot need a PLB if they already have an onboard ELT?  How would a PLB help a pilot in an emergency?  What is a PLB anyway?

San Carlos Flight Center invites Chief Pilot Herb Patten to explain the critical differences between PLBs and ELTs.  In this seminar, he will review the history of the emergence of regulations on ELTs, review accident data that highlights the problems and challenges of the original ELT design, describe the enhancements offered in the new 406-MHz ELT and how they function and provide an update on the proposed regulations for ELT requirements.

Most pilots are aware of the onboard Emergency Locator Transmitter (ELT) in their personal or rented airplanes.  Most know that the older models transmitted a distress signal on 121.5-MHz in the event of a hard landing.  But how many know what frequency the new models transmit on?  How does an ELT differ from a PLB?  Do you know the differences in who receives your distress signal and how quickly?

Don’t miss this seminar if you want to be prepared in post-emergency landing situations, and how you can increase your chances of surviving through the use of ELT’s and PLB’s.
