Thanks Tu
The Mk-3 and Mk-4 Rules are very popular with FJ pilots and have been for 17 years. The Mk-2 is being redesigned for GA use in 1: 500,000 scale. It will be for planning on Jeppesen charts and for GPS equipped light aircraft. There will be no speed scales. just nautical miles, kilometers, cm and inches for Jepp charts. The Mk-1 is for quarter mil / UAS type flying for speeds from 80 to 150 knots. If anyone wants one or more info, email me direct on

PS: now knackered old fart flying rubber dogs**t from the far east.
