It is understood that the start time of the 2011 Australian Grand Prix could be moved forward by an hour following complaints from a number of drivers regarding the failing light during this year's event.

Ahead of this year's race, a number of drivers, including newly elected Grand Prix Drivers' Association chairman Nick Heidfeld, expressed concern, though, talking to Pitpass, the German was keen to make it clear that his opinion was his own and that he wasn't speaking officially on behalf of the drivers' union.

"Last year the sun was low which was a problem, particularly on certain parts of the track," he said. "Yesterday when it was very cloudy it was actually even worse. We would definitely like to have it earlier.

"Most of the other drivers have expressed similar feelings, that they don't like having to start at this time," he added. "Many people think it's dangerous."

Former GPDA chairman, Pedro de la Rosa, now driving for Sauber, shared the German's concern. "We are not comfortable with the fact that if it's wet there will be less light," he said.

Measurements taken during last weekend's Grand Prix by the FIA revealed light conditions fell below the minimum requirement, even for night racing conditions. Visibility was so bad for racing to continue in future at that time Albert Park would need lights.

The Australian Grand Prix Corporation has previously stated that lights were not an option for the temporary parkland circuit, meaning the only alternative is for the start time to be adjusted.

While no announcement has yet been made by the Australian Grand Prix Corporation, any change will also need the approval of the commercial rights holder, the very person responsible for pushing the start time back in the first place.

"In Australia it was certainly over the limit by the end of the race, it was certainly too dark," said Michael Schumacher, according to the Herald Sun. "I understand that the FIA has measured this and will take action for next year, sometimes you have to have the experience. There seem to be some guidelines now on what light you have to have as a minimum."

"It's risky," added Robert Kubica. "Like today if there were big clouds, heavy rain and a lot of spray it would just be too dark."

"After Australia we already complained twice," he continued. "I think the FIA did some measurements and it's clear that it's just too dark for the safety targets they've put, so I think it's a serious problem."

The Pole suggested that if the late race start is an attempt to maximise TV viewing figures in Europe - the sport's traditional heartland - F1 bosses might consider scheduling the race so that it is shown in Europe on Saturday evening.

However, the thought of having to show Formula One in place of Doctor Who, Over the Rainbow, The National Lottery: Who Dares Wins or Casualty, would surely send some BBC bosses apoplectic.
