| The halo, which is fixed to the cockpit at three points 
				including a central pillar right in front of the driver, made 
				its debut in Spain earlier this month.
 F1 outfit Red Bull, whose team principal Christian Horner has 
				expressed misgivings over the halo's design, are developing a 
				separate device but Whiting said it was unlikely to be ready in 
				time for 2017.
 
 "I think (the halo's) going pretty well," Whiting told reporters 
				at the Australian Grand Prix in Melbourne.
 
 "It's been tested quite extensively now, and I think it will 
				offer very good protection for a flying wheel, for example, 
				that's the main way it's been tested so far.
 
 "We need to do a thorough risk assessment on it, we need to look 
				at a number of other related things like extrication. We've got 
				to talk to the medical crews about it. But I think it's going 
				quite well."
 
 Improving head protection became a priority after the deaths 
				last year of Briton Justin Wilson, a former F1 racer who 
				suffered head injuries from debris in an IndyCar crash, and 
				Frenchman Jules Bianchi.
 
 A working group led by Mercedes and Ferrari hoped to set 
				standard specifications for the halo by the end of May to allow 
				teams to incorporate it into their designs for next year's cars, 
				Whiting said.
 
 Most drivers favor the halo, but some have reservations about 
				how quickly they could get out of their cars after an accident.
 
 Whiting had few concerns about that, though, pointing to 
				Ferrari's test of the device in Spain.
 
 "One team did put a halo on their car, and did get the driver to 
				see how quickly they could get out, and it looked perfectly 
				simple, and arguably easier, because the driver can get hold of 
				this thing and lift himself out much easier," he said.
 
 "It looked very simple, I must say."
