The three races would join Australia, Monaco and France on F1’s “officially cancelled” list.
The conditional schedule kicks off with a double-header in Austria as planned and would conclude in Abu Dhabi on December 13.
Belgium and Hungary appear on the list despite bans on public events that will be in force in both countries at their respective race dates.
Hockenheim is also listed as a possible replacement for the British Grand Prix at Silverstone.
Scheduling events is the easy part for Formula 1 but reaching commercial agreements that make financial sense for the sport and each promoter will be a challenging task.
Most race organisers – like Silverstone – have demanded that Liberty Media assume all costs of putting on a race. But fly-way events are expected to contribute a significantly reduced fee.
Insurance considerations linked to race cancellation triggered by the pandemic are also likely to factor in to the organisers decisions to host or not an event.
