The new LF-ULB
SID88 is a low frequency ULB for aviation, transmitting on a frequency of 8.8 kHz. The beacon is intended to be installed on the aircraft structure.
All aircraft with a maximum take-off mass of over 27,000 kg operating over oceanic areas are to be fitted with the low frequency ULB by January 1, 2018.
EASA issued Opinion No.1 in 2014 requiring all aircraft to switch to 90 days beacons meeting FAA‘s TSO-C121b as of January 1, 2018.
The 90 Days ULB
BLUE90 is an ULB with an operating time of 90 days after activation. The lithium content of the battery is less than 1 gram, so there is no restriction for transport.
The right periphery keeps your BLUE90 running. Quick and safe.
The Ulyser is a battery-powered receiver for acoustic signals with a frequency of 5 to 50 kHz.
