Ferrari says Kimi Raikkonen reported visibility was "OK" on his solitary lap testing the Halo safety concept in Barcelona.
On Thursday morning Raikkonen took to the track with a cockpit protection device fitted to his Ferrari SF16-H. The Finn completed an installation lap before returning to the pits, where he told the team visibility "was OK".
The team confirmed to the media it was a temporary carbon fibre structure designed by Ferrari to test visibility. Ferrari said it was "pretty close" to what it expects a final design to look like, albeit slightly wider, and added it did not have a hinge for easier driver extraction because it was a prototype intended for a single lap.
The FIA continues to conduct research into cockpit protection, something it is keen to implement from 2017 onwards, with the blessing of the Grand Prix Drivers' Association. The recent meeting of the F1 Commission pushed back the final decision on cockpit protection until the end of April, with two possible concepts in the running.
