===== In Air ATO Exec Order Cx, why do I see an "InvalidatedInstruction" which later launches? =====

InvalidatedInstruction means the ATO instruction is no longer valid, since the target is no longer active or is not a valid target (i.e. is in a no-fire zone), or the ADP controller which is launching the Flight has determined that the intercept is no longer valid (ex. target Flight changed course).  It is possible for an alert DCA Flight to cancel several times in this instrument (due to invalid intercepts), but then later launch on a valid intercept.  This is the only case in this instrument where the order cancellation is not necessarily "permanent".  

Note:  If the Flight has no controller at this point (autonomous), it will launch%%--%%not knowing that the intercept is not valid

For a complete description of all the reasons for cancellation shown in this instrument, see the separate file "JAS Misc Instrumentation Explanation.doc"
