摘要: | 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 II~FMS combination is subject to problems that have affected the IIS at some airports, including frequency congestion and FM radio interference. |
