In this paper future aeronautical application areas of high speed optical communication terminals have been introduced. Aspects which influence the terminal design have been discussed. Decisions on the link-design depend on the application scenario. Nevertheless it has been pointed out that OOK (On/Off Keying) modulation at 1550 nm is preferable for avionic free-space optical (AFSO) communication. Terminals which are used for satellite- or HAP (High Altitude Platform)-up/downlink are simple to design as one can work with fixed wavelength in these asymmetric scenarios. Simplex and half-duplex transmission schemes can easily be implemented for symmetric links but bear some drawbacks concerning throughput and PAT (Pointing Acquisition Tracking)-performance which again reduces communication performance. More complex designs allowing arbitrary connectivity would be needed for a real MANET (Mobile Ad-Hoc Network) allowing the connection of all potential avionic communication partners.
