As previously confirmed, Felix Rosenqvist and Patric Armand will make up the Status line-up for Wednesday, while Jordan King and Sergey Sirotkin will link up at Racing Engineering.
Norman Nato will continue running for Arden, joined by Gustav Malja, while Nato's 2015 teammate Andre Negrao will test alongside GP3's most experienced driver Alex Fontana at Rapax.
GP3 runner-up Luca Ghiotto, who has been linked to the Red Bull Junior Team, will be alongside another GP3 frontrunner Jimmy Eriksson at Trident.
