Abstract: The link operation modes are closely related to system performance, capacity and redundancy of air ground VHF data link. The effects of two existing different link operation modes (CAT A and CAT B) on performance of VHF data link are presented. The analysis is based on embedded Markov chain model. Simulation examples are given and compared. A new and effective link operation mode is proposed.

Key words: VHF data link, air-ground communicat ion, link operat ion mode
