Does my memory serve me correctly?  Can you not produce a form of Mercator chart based on any Great Circle, namely the Oblique Mercator?  Have I not seen this produced for a frequently used route by an organisation, e.g. a pilot’s Enroute Chart for the route between Akrotiri (Cyprus) to Brize Norton (UK)?  So long as you’re not intending to wander far off track, and you’re not expecting to do much plotting (which might give you neck ache), might such a projection have all of the qualities of the ‘ideal chart’ in this limited application?  Or are my memories playing tricks on me?  DaveP
