406-MHz ELT required to meet JAA/ICAO standards
As reported last month in AIN, under FAA requirements civil jets must be equipped with ELTs starting this month.

As reported last month in AIN, under FAA requirements civil jets must be equipped with ELTs starting this month. U.S. operators have been advised to consider installing 406-MHz units because satellite monitoring of 121.5-MHz units is scheduled to end in 2009.

But AIN recently discovered that 406-MHz units will be required for some operators much sooner. Under a little-known JAA requirement and separate ICAO standard, starting next January 1, most large civil airplanes operating internationally must be equipped with at least one 406-MHz ELT.
