I am wondering if one could print A3 tiles of SD charts and use them to meet the legal requirement to carry a chart. Digital & paper copies of UK CAA charts alone is around £150/yr. Waterprooof, foldable A3 inkjet paper is around £1/sheet (toughprint & weatherjet) and say another 50p for the ink. Also makes huge sense for the odd trip to France, Ireland etc. Not sure what happens re "drawing line on map". Perhaps one can use chinagraph  .. cleaning line with meths wd doubtless clean the chart off as well!

Anyone more clued up than me re the regulations?

David

Have done a bit more digging. Regulations say as follows:

Further to our recent conversation the carriage of charts is a grey area; however Section 1, Schedule 4, Page 17 of the Air Navigation Order (CAP 393) states that aircraft equipment should include “Maps, charts, codes and other documents and navigational equipment necessary, in addition to any other equipment required under this Order, for the intended flight of the aircraft including any diversion which may reasonably be expected.”

For Tim

What we now need to be able to do is print SD charts as contiguous tiles in A3 format at a designated scale (1/2 mill is my preference).

Tim  .. how about it?
