Jules Bianchi says he is not fazed by switching from Marussia to Ferrari for the second day of the third in-season test at Silverstone.
Bianchi, who conducted tyre testing in the MR-03 on Tuesday morning, ended the day in fifth position, although his 108 lap programme came to an end due to a small fire.
The Frenchman will replace Kimi Raikkonen at Ferrari for the second day of testing on Wednesday, as the Finn continues to rest following his accident in Sunday's British Grand Prix.
"I did it already in 2012 when jumping from Ferrari to Force India, [I] will do it again so it’s good, good experience and this is what I need to grow up and I’m pleased with that."
Raikkonen is expected to be fit in time for the German Grand Prix but Bianchi says he would be ready if Ferrari came calling.
"Of course, in Formula 1 you have to be ready for everything," he said. "At the moment I am racing with Marussia and want to do my job with them, happy with what we are doing at the moment.
Bianchi also believes that Marussia will face a tough job to retain ninth in the Constructors' championship although insists that simply beating Caterham remains their target.
"At the moment they [Sauber] are quicker than us, we are trying to catch them but it is not easy," he said.
"We are still in front in the championship and our target is to be in front of Caterham, if we are in front of Sauber it’s good but that’s not our target."
