The history and future of landing systems

Share

The lecture will go through the history of aircraft approach and landing systems, from the early aviation times. The basic principles for Instrument Landing System (ILS), unchanged since 1947, will be described.



Significant technical improvements over the 70 years have resulted in a much longer life for ILS than expected. ILS is still by far the most used landing system, despite ICAO’s standards for new concepts. The reasons new concepts were not successful, are twofold: Difficulties to show financial benefits over costs for individual operators, and con- certed action with all involved stakeholders. This has resulted in, up to now, far less implementation of satellite-based landing systems than expected. Hence, ILS might celebrate its centennial before such systems take over as the preferred aircraft landing system.

The history and future of landing systems

Significant technical improvements over the 70 years have resulted in a much longer life for ILS than expected. ILS is still by far the most used landing system, despite ICAO’s standards for new concepts.

Hence, ILS might celebrate its centennial before such systems take over as the pre- ferred aircraft landing system.

Biography:

Dr. Thor Breien has been with Indra Navia, Oslo, from 1979 to 2020. From 1970 to 1978, he was research scientist at The Norwegian Institute of Technology. He got his diploma and PhD in telecommunications and electromagnetics in 1970 and 1978, respectively.
Dr. Breien has held different technical management positions in the company above, including director R&D. His main research has been within computer assisted modeling and assessment of the terrain’s effect on signal performance for Instrument Landing Systems (ILS). He has presented papers at several international conferences, including ICAO, plus has written a book in Norwegian titled “The history of the Norwegian ILS”.
