As a bit of a Luddite myself, I still prefer to do things the old fashioned way - map, protractor, ruler etc. However, there is no doubt that SD is an impressive piece of kit which has a place in todays GA environment. All that being said, I see too many pilots spending too much time with 'heads in' rather than 'heads out'. The ideal solution I guess is for the occupant of the left hand or forward seat to fly the aeroplane whilst a colleague alongside or behind looks after SkyDemon - in my day they used to be called navigators !
