Original file (2,474 × 1,940 pixels, file size: 1.73 MB, MIME type: image/jpeg)
A depiction of the Mark III IFF system. The sharp upward points on this A-scope presentation represent the target return pips. The IFF response shows as a downward deflection immediately following the target pip. The transponder in the airplane could be set before a mission to return a sequence of three coded IFF responses a few seconds apart. Each response could be either a narrow or a wide response. There were six combinations for the coded responses that could be used to represent a prearranged code of the day, or to represent aircraft on different missions. The pilot could also throw a switch that caused a very wide response meaning an emergency condition. From RADEIGHT p. 64, Figure 53
