Robert Kubica has completed a private one-day Formula 1 test in the Williams FW36 as planned.
The Polish driver has been away from F1 since 2010 when he suffered a horrific rallying crash at the start of 2011 and was left with only partial use of his right arm.
Kubica, who has competed in WRC and a handful of sportscar outings since recovering, is eager for an F1 return having enjoyed three tests with Renault before being passed over by the French manufacturer who opted to take Carlos Sainz Jr on a one-year loan from Red Bull.
