IO540,
Agreed, the moving map situation could well be a solution, particularly if something like the CAA charts (1:500,000, 1:250,000 and 1:50,000) are used as the data source and regularly updated (even better, use the MOD military charts which are up dated more often). But the £100 camping GPS can also be used PROVIDING the user takes the time to put in a proper route which considers all the NOTAMs and current charts. As can more traditional methods, but again with the appropriate training in their use.
I would challenge your argument that situational awareness is best provided by moving map GPS, although I think it rather depends on the type of flying you are doing. Sure IFR flight SA is adequately fulfilled by moving map. In our situation of low level VFR navigation, a 1:250,000 chart suplimented by the appropriate 1:50,000 OS Map as required gives better SA than the current breed of moving map GPS units (at least those available to the consumer market). Having said that it depends on the map reading skills we have been taught and maintain.
I personally believe that the infringement issue will only be solved when pilots learn how to navigate and plan properly. How people choose to navigate is largely upto themselves and what sort of flying they do. But however they do it, they must understand how to do it properly, be able to gross error check their progress and have a plan B when the seagull chooses to poo on their wings. I don't think it is necessary to mandate the use of moving map GPS, but I do think that a wider use of 1:250,000 charts would help.
