A few aircraft that I fly, such as Archer III, have fold down sun-visors, that I find a great help when returning to runway 26, just before sunset.
These are similar to car sun-visors, but are made of see-through plastic, that is tinted like dark sun glasses. As far as I am aware, these are standard kit on new Pipers, so presumably approved by the CAA, for Public AoC aircraft.
So, question for our engineering guru,
Ghengis:-
Could similar sun-visors be retro fitted to all light aircraft, or would that require a CAA minor mod authorisation, and, of course a large cheque to the CAA?
