I was thinking that transient jumps in the radio nav would be rejected
when compared to the INS.  But, since the DC-10 is an old analog system,
maybe there is no comparison or filtering of the radio nav and INS as
they go into the autopilot.  There might be just a simple switch that
selects INS for over water and radio nav for land.  In this case, it is
possible (but highly improbable) that a CD player could effect the radio
nav (which is forward and under the cockpit).
