The second helicopter (Helimed 98, registration G-CEMS) was originally based at Sheffield City Airport but moved in March 2012 to RAF Topcliffe near Thirsk. A spokesman for the charity commented: "What we're looking to do is provide the very best coverage for the whole of Yorkshire, for the five million population. The people of Yorkshire are better served with an aircraft at Thirsk and one at Leeds Bradford." In 2016, the second helicopter was replaced by G-YOAA as part of the air ambulance's fleet renewal programme.
