Humble aplogies to all, of course its mounted by the #1 EGT gauge (ANOTHER senior moment on my part). The RCICS, Reheat Capabilty Indication Control Sub-system (Oh OK then, I just made that up
) was fiitted in the very early days of Concorde operation. It looked at first sight a belated April Folls joke, but as was said (much) earlier prior to this
amazing piece of technology the #3 INS CDU waypoint thumbwheel was used as the reheat GO/NO-GO indicator.
And NB2A, no apologies needed from you sir. A great link to the video starring Dave Rowland and Roger Bricknell (sorry Les).
Best regards to all
