  • What is the history of Navtech Navigation Data?

    In 1956 an advertisement appeared in "Flight" depicting "The Decca* Navigator". Based on technology developed over the previous 15 years this was a ‘moving map display' from which all FMS capability was designed. Since then, Flight Management Systems have developed into technology that not only navigates, but controls and warns as well. Navtech has been at the forefront of all these milestones developing a database of more than 1.75 million records detailing all major airports and airways. Today, the careful processing of the vast volume of information that comes from states and customers worldwide keeps alive the story told in that 50 year old advertisement.

    *Decca is a reference to The Decca Company who was responsible for the Decca Navigator System which produced low frequency radio signals during WWII to help pilots achieve accurate landings.  The Decca Company was purchased in 1979 by Racal Electronics who in January 2000 was bought by Thomson-CSF and which later became The Thales Group.

  • How does Navtech Navigation Data meet IOSA requirements?

    IOSA auditors require a demonstration of a verifiable source of information to feed the FMS. EU OPS, FAR and also require that data comes from an authentic source and that the information is traceable, accurate and current. Navtech has a library of AIP from all member states converted into an electronic format for use across the company. Augmented by NOTAM and supplement subscriptions, the state information is transcribed into chart, or FMS data in ARINC 424 format for subsequent passage to FMS manufacturers where it is converted and packed for use on the aircraft. For standard data no other sources are used. For tailored procedures, the operator provides the requirement and procedure design with a waiver accepting responsibility for the data. As per relevant standards such as ED-76, the chain is unbroken from state to aircraft and the Quality System employed to guarantee its integrity meets ISO 9001 and EASA/FAA Letter of Acceptance Type 1 requirements. In this way, an IOSA auditor can be satisfied that all data obtained from Navtech meet the stringent demands of traceability and integrity.

  • How does Navtech Navigation Data meet EU OPS 1.873 requirements?

    Operators are required to use data which is provided by a supplier holding a Letter of Acceptance Type 2. Type 2 suppliers pack data into formats which conform to the proprietary requirements of their FMS equipment. This is a process which requires data from a reliable and verifiable source. Holders of a Type 1 Letter of Acceptance are such providers and, as described above, meet the stringent requirements of EASA and FAA regulators to submit data transcribed from source documents into ARINC 424 format for subsequent processing. Some FMS manufacturers  present the data directly to the operator; others send it back to Navtech for distribution. In all cases, the data comes from a Type 2. provider. In some cases Navtech acts as a distributor and will contract with an operator to supply data to the FMS manufacturer and distribute to the operator. What is certain is that contracting Navtech to provide source data is a wise move and Navtech ensures the integrity and traceability expected by regulators, manufacturers and operators.
