Thankyou everyone for the feedback

Use the scale at about halfway along from the latitude scale next to the 10w

mad_jock, can you please elaborate a little bit. If I have understood correctly then measuring from 60N along 10W meridian halfway (till 62.5N) is about 6.cm.

That means 6cm for 2.5deg or 150nm. 1cm = 23nm

Ingo to SUM = 21.5cm

23 x 21.5 = 494 (quite precise)

Is it just a fluke or that's what u mean. For measuring distances on other parts of the charts, at which point do you establish the scale?

Regards
