Based on the above quote from the ANO, it seems to revolve arround the necessity of having a chart on a particular flight. Taking that at face value, one could argue that when operating a VFR flight over well known territory, no chart would be required.
However, the actual ICAO requirement to which the UK has no difference is that the aircraft shall carry - "current and suitable charts for the route of the proposed flight and all routes along which it is reasonably expected that the flight may be diverted."
This seems to make it much clearer as under the ICAO requirement there is no situation where the pilot can fly with no chart.
But, a scribbled pencil drawing of the local area on the back of a fag packet could be just as up to date and useful as a full colour map.....perhaps even more so if required frequencies and procedures are included.
Overall, I don't think that anyone would drag someone over the coals for flying the circuit with no 1:500,000 chart provided that they had all the airfield information required to make a safe flight.
Flying cross country (legally more than 3nm from the field) is a different matter.
