addition transmitter 15 and receiver 20 are replaced in fig2 a by transmitting receiving t r device 41 and transmitter 19 and receiver 16 are replaced in fig2 a by transmitting receiving t r device 44 within aircraft control apparatus 43 decisions may be made by 40 using algorithms stored therein decisions may be based on a aircraft identification communicated by 18 to 44 to 41 to 40 b other aircraft telemetry signals as discussed hereinabove and communicated by the same path as the aircraft id hereinabove and c previously stored landing parameter information as discussed hereinabove along the path 9 within 3 to 44 to 41 to 40 40 may be one computer a group of computers a part of one computer or a part of multiple computational devices 42 may be a ground station an airborne station a water based station a space based station in addition 42 may be located on one or more controlled aircraft as shown in fig9 hereinbelow in such a case 41 would link 40 to units 44 and to the elements coupled to 44 on other aircraft but 40 would not need an rf link in order to exchange signals with 3 and or 18 on its particular aircraft u2014 i e the on aircraft connection between 40 and 3 and between 40 and 18 could be hard wired in one embodiment of the invention a supervisor would over read the decisions of 40 if desired the supervisor could negate them or provide alternative decisions the apparatus for such a hybrid control station would require the hardware that comprises 42 as well as elements 13 and preferably 21 of element 11 in fig1 a in addition switching means not shown in the figure under.
