I am dyslexic and yes I had real problems coming to grips with NDB and VOR tracking (because I would 'lose the plot'), although I also feel the lack of explanation from instructors did not help...
Eventually I made myself models of a beacon and a plane and explained it to myself and broke it down into into simple understandable/repeatable chunks/actions/methodology which I still used to the day I stopped flying...
The real knack with dyslexia is exactly that...learn to work around it and devise your own methods/systems to do so...and most important never be rushed into an action as you will inevitably make an error...so you take 5 secs longer than your colleague to work out a bearing/heading etc. so what at least you have thought it through and it will be right
