Lufthansa Systems has announced is has received the Letter of Acceptance (LoA) Type 2 from the European Aviation Safety Agency (EASA) for its Lido/AMDB airport mapping database. This LoA certifies navigation data for delivery to end users. Lufthansa Systems supported the EASA significantly in developing the complex test procedure and is the first provider of airport mapping data to be certified by EASA.
The airport mapping database supports pilots during all taxiing procedures that could pose a challenge depending on the airport size and weather conditions. In order to ensure the safety of the passengers and crew, the Lido/AMDB data needs to be absolutely reliable.
In 2014, Lufthansa Systems received the LoA Type 1, which confirms that its processes for producing airport layout data comply with the conditions and quality standards required by EASA. In certain types of aircraft, such as the Airbus A350 and A380, these data are more closely tied to the aircrafts’ avionics systems and must therefore meet the special test requirements of the LoA Type 2 from EASA.
In the A350, for example, the Lido/AMDB data is used in calculations made by the Runway Overrun Prevention System (ROPS). The ROPS on the A350 is an additional function of the Brake to Vacate system (BTV), which calculates the necessary braking distance during the approach with the help of Lido/AMDB data. If there are deviations, the system supports pilots by alerting them if the available landing distance has been determined to be too short.
