Cant see what use having an IR rated pilot would be ?
Well not if you are flying legally. the caa has put 600 AGL and 3KM vis as the minimums, as most of the stages are in the hills, if you can fly you within the CAA minimums there would be no need to
"This year, the CAA has created Restricted Areas (T) around the Rally sites, and only registered helicopters will have permission to enter. Please see AIC that will be issued shortly, and for AOC holders, FODCOM 29/2007. Weather limits inside the RA(T) will be a minimum of 600 ft agl cloudbase and 3 km visibility"
