Ferrari's main aim of testing the Halo cockpit protection was to check the visibility of the concept.
Kimi Raikkonen ran the proposed cockpit protection during his installation lap on the penultimate day of pre-season testing at the Circuit de Barcelona-Catalunya, with the design screwed in to the top of the chassis where cooling vents sit either side of the cockpit. The final design proposal would see it integrated in to the chassis itself with hinges.
While the prototype used on Thursday was made of carbon fibre and wider than Ferrari expects any final design to be, Raikkonen reported no problems with visibility while completing his first lap of the day.
Ferrari produced the prototype itself, but will not run it again during this week's test having had the initial feedback on its impact on visibility.
