to fig4 a flow chart illustrates the operation of the acif interface software object 20 and the core pod software object 25 this flowchart is described in the context of an exemplary 1553 physical interface it should be noted that other physical interfaces could be used in place of the 1553 physical interface the acif interface software object 20 provides a first auto detection layer 21 which is initiated with the execution of the start step 41 in step 42 the targeting pod 11 is powered on in step 43 the terminal address of the aircraft 10 is evaluated and in step 44 1553 messages are transmitted between the aircraft 10 and the targeting pod 11 in step 45 there is an interrogation of the 1553 message characteristics behaviors which completes the auto detection layer 21 the event completion within the auto detection layer 21 however will vary depending upon which type of aircraft 10 acts as the host in step 46 the software enters a dynamic instantiation layer 22 in which the matching acif object 20 corresponding to the host aircraft 10 is dynamically instantiated in object technology instantiate means to create an object of a specific class this is essentially a one time event in step 51 the software enters a translation layer 23 by capturing the currently received 1553 messages from the aircraft 10 in step 52 the received 1553 messages are translated to the targeting pod 11 in step 53 the targeting pod 11 responds to the translated messages in step 54 the pod status is translated to a 1553 message in step 55 the pod status is transmitted via a 1553 message to the aircraft 10 the steps 51 55 of the translation layer 23 are a continuous series of events which.
