Tailerons?? On a Jaguar.. Please don't dirty the aeroplane with that Tornado terminology
Perhaps my memory is playing tricks but I'm sure we called them "Tailerons" on the Jaguar long before the MRCA took to the skies. I agree that the "system" was known as differential tail plane but I thought we referred to the individual controls as "Tailerons". It was a long time ago though and I did later work on Tornado.
