Salut,
"""There’s change in the air…
As an aircraft owner, the new date you have to be aware of is January 31, 2009—yes, 2009. But itʼs never too early to start planning. On that date, all aircraft with ELTs will be required to be equipped with a digital ELT operating
on the 406 megahertz frequency.
And this means you.
Why? Because that is when the emergency 121.5 analog frequency will no longer be monitored
by the COSPAS-SARSAT search and rescue satellites"""""
