Max Verstappen set the pace on a cold and grey Friday morning in Shanghai in a practice that was red flagged twice because the medical helicopter was unable to fly in the conditions.
The session was red flagged after five minutes with the FIA reporting “session stopped, medical helicopter not able to operate.”
As dense cloud covered Shanghai on a cold and grey morning, visibility deteriorated meaning the helicopter was “not able to land at the designated hospital” and therefore the cars were not permitted to run.

The session remained red flagged until 10:47 local time leaving the drivers with just under half of FP1 to run.
Kevin Magnussen and Romain Grosjean had spins at Turn 9, Felipe Massa cut the grass as he slid off the track, Carlos Sainz lost the back end of his STR under braking and Max Verstappen set the early pace – a 1:50.491.
The Virtual Safety Car came out when Nico Hulkenberg spun and beached his Renault in the kitty litter at Turn 3.

Minutes later the session was red flagged for the second time due to medical helicopter “not able to operate” again. The FIA revealed that the “weather conditions have forced the closure of the local airport.”
FP1 did not resume with Verstappen finishing P1, 1.595s up on Felipe Massa while Lance Stroll was third, a further four-tenths off the pace.
Sebastian Vettel, Lewis Hamilton, Kimi Raikkonen, Sergio Perez, Esteban Ocon and Jolyon Palmer did not set times.
