Ferrari tester Giancarlo Fisichella gave the Scuderia's F-duct device its track debut at the weekend at Vairano.
The Italian also used the time to try out some other developments for the F10, which will be further evaluated by race drivers' Fernando Alonso and Felipe Massa on Friday, during practice for this Sunday's Spanish Grand Prix at Barcelona's Circuit de Catalunya.
"After a very busy week of testing on the bench and in the wind tunnel, this morning saw the on-track baptism of the management system for the blown rear wing," confirmed a statement on Ferrari's official website on Saturday.
"It was tested at Vairano by Giancarlo Fisichella as part of the four days of aerodynamic testing allowed in the testing agreement, as defined by the twelve teams.
"This was not the only new element evaluated by the Scuderia's third driver. The F10 was also fitted with the aero configuration that it is planned will be used at the Catalunya Circuit during next Friday's free practice for the Barcelona race, including a new position for the rear view mirrors which must now be located on the chassis.
"Track data acquired today will be analysed by the team over the next few days and then, also depending on how things go in the two free practice sessions on Friday, a decision will be taken as to whether or not to use all the updates for qualifying and the race."
