Your right as there is no requirement to operate in True while in the tracks. The company I flew for operated in True at anytime we were in Class ll airspace...regardless of latitude. Since I have left I understand that they switched back to Mag in Class ll airspace. Go figure. I agree that True is a more honest navigation reference but policy is policy and it's hatf to convince many of the younger crowd what works best. Obviously switch back to Mag after leaving Class ll airspace in a signifcant event after a crossing and coasting in to the radar enviornment.
