The Australian's last full world championship campaign was with Foggy Petronas in 2005, which he finished just 23rd in the points, before the 'Slide King' reappeared in MotoGP with Ilmor at the tail end of 2006.
McCoy was then overlooked in favour of Jeremy McWilliams and Andrew Pitt for Ilmor's ill-fated 2007 MotoGP campaign, but looks set to be back in world championship racing next season with the new Caracchi-run Triumph team.
On the first day of the Qatar test, McCoy put the 675 triple 3.7secs behind fastest man Broc Parkes on its WSS debut, with team-mate Paul Young a further five seconds slower.
