A hybrid-duplex aeronautical communication system (HBD-ACS) consisting of a\nfull-duplex (FD) enabled ground station (GS), and two half-duplex (HD)\nair-stations (ASs) is proposed as a direct solution to the spectrum crunch\nfaced by the aviation industry. Closed-form outage probability and finite\nsignal-to-noise ratio (SNR) diversity gain expressions in aeronautical\ncommunications over Rician fading channels are derived for a successive\ninterference cancellation (SIC) detector. Similar expressions are also\npresented for an interference ignorant (II) detector and HD-equivalent modes at\nGS and ASs. Through outage and finite SNR diversity gain analysis conducted at\nthe nodes, and system level, residual SI and inter-AS interference are found to\nbe the primary limiting factors in the proposed HBD-ACS. Additional analysis\nalso revealed that the II and SIC detectors in the proposed HBD-ACS are\nsuitable for weak and strong interference scenarios, respectively. When\ncompared to HD-ACS, the proposed HBD-ACS achieves lower outage probability and\nhigher diversity gains at higher multiplexing gains when operating at low SNRs.\nFinite SNR analysis also showed the possibility of the proposed HBD-ACS being\nable to attain interference-free diversity gains through proper management of\nresidual SI. Hence, the proposed HBD-ACS is more reliable and can provide\nbetter throughput compared to existing HD-ACS at low-to-moderate SNRs.\n
