F1 has provided an update to the running schedule ahead of qualifying for the Russian Grand Prix and revealed any running is dependent on the local airport being able to open.
The plan is now dependent on the medical helicopter being able to being operational in order to allow running to get underway as conditions improve.
An FIA statement read: “An updated timetable has been issued with the next session being F1 qualifying at the originally scheduled time.
"While the conditions at the track have improved, there is still inclement weather in the local area that is affecting the airport and road network.
"This is why there won’t be any running between now and F1 qualifying, by which time we expect the local airport to reopen so that our medical helicopter can return to being operational and the session can go ahead as planned.”
