The FIA has made provisions to eliminate the possibility of the Sunday's Chinese Grand Prix being cancelled for the same reasons that Friday practice was abandoned.
Track running was limited to just a handful of laps on Friday because the medical helicopter was unable to operate in the low-lying cloud at the FIA's designated hospital in Shanghai. Under its own sporting code, the FIA will not run a session if it cannot guarantee a transfer time of around 20 minutes to the nearest hospital with neurosurgery capabilities.
In China the closest qualifying hospital is the Huashan Hospital 38km away from the track, meaning a road transfer would take too long.
