GKN Fokker Services has delivered its 500th
Underwater Locator Device (ULD) modification package, in just one
Controlling the location of aircraft
flying a long-range over oceanic areas has become increasingly
important to air traffic control authorities. This has led to new
requirements, including the introduction of a stand-alone,
long-range ULD. Multiple countries now mandate fitting the ULD on
aircraft for long-range over-water flights.
The ULD will transmit an 8.8 kHz acoustic signal
(pinger) for a minimum of 90 days. Its low frequency ensures an
increased detection range of 13-22 km (7-12 NM) over the standard
ULBs as installed on Flight Data Recorders and Cockpit Voice
The ULD is installed on the airframe and the
maximum operational depth is 6,100 m (20,000 ft) when activated
upon immersion in both salt and fresh water. The battery is a
single-cell type with a six-year life.
Erik Lous, Product Manager ULD at GKN Fokker
Services said, "We are happy to reach this milestone of delivering
500 ULD modification kits, only one year after supplying the first
unit in October 2017."
The modification package has been developed for
a wide range of aircraft including the Airbus A320 Family, A330,
A340, Boeing 737 through 787, Bombardier Q400, Embraer E-Jets and
the Fokker 70 and Fokker 100.
The GKN Fokker Servicesí solution offers a
complete package including the engineering bulletin, aircraft
documentation, the ULD hardware, installation kit and a tester.
Thus far, the ULD modifications have been
supplied to twenty-five customers in twenty countries.
