Louis Deletraz has ended the only practice session of the Formula 2 weekend on top of the timesheets as he posted a time of 1:14.782.
Ghiotto had the biggest scare of any driver during the session as in the middle sector, he skipped through the gravel after correcting the car when entering Turn 6.
Drivers settled down in the latter stages of the session as they focused on their race stints and conserving the tyres, which are set to provide difficulties in the hot temperatures.
Three drivers made their first appearances of the year in the session, with Arjun Maini returning to the series with Campos.
The Indian driver was 16th in the timesheets, ahead of Patricio O'Ward and Ryan Tveter, who make their first ever starts int the Formula 2 championship this weekend.
