The Low Frequency Underwater Locator Device (LF-ULD) is a self-powered device that provides an effective help in order to improve the search and recovery of submerged aircraft. The LF-ULD is not to be confused with the ULD, also known as Underwater Locator Beacon (ULB) that is installed on the Cockpit Voice Recorder (CVR) as well as the Flight Data Recorder (FDR) and emits ultrasonic impulses at 37.5 kHz. The LF-ULD will be mounted directly at the structure of the airframe and supplements the existing ULDs. Once the LF-ULD is emerged into water, it is being activated automatically and transmits at frequency of 8.80 kHz. Due to its lower frequency range the LF-ULD has a far longer detection range of at least 90 days after activation.

Automatic Dependent Surveillance- Broadcast (ADS-B) is the replacement and augmentation of RADAR-based aircraft surveillance technology. With ADS-B, the surveillance of aircraft does no longer rely on RADAR ground stations, but on aircraft based GPS receivers. Aircraft equipped with ADS-B broadcast their precise position and velocity data, as well as altitude and supportive information automatically and with no pilot or external input to ATC or to other aircraft.

The above listed EASA STC has been validated or approved by the following aviation authority agencies:

• FAA (ST04266NY, Date of issue: 2018/11/06)

• ANAC (2019S08-17, Date of issue: 2019/08/08)

The growth of aircraft systems operated by onboard loadable software and the extinction of 3,5” Floppy-Disks make common Airborne Data Loaders (ADL) / Multipurpose Disk Drive Units (MDDU) more and more inconvenient.

Lufthansa Technik (LHT) provides a plug and play Data Loader Connector Panel (DLP) for easy connection of any ARINC 615 Standard Portable Data Loader (PDL). Software Upload effort can be reduced remarkably with a modern Portable Data Loader connected to the Data Loader Connector Panel.
