Abstract:

All three alternative systems under development can potentially provide greater precision landing capabilities than the 11. For example, all three systems allow curved approaches to the airport, which enhance its capacity because more aircraft can approach an airport at the same time. However, the IIFMS combination is subject to problems that have affected the IIS at some airports, including frequency congestion and FM radio interference.
