             FRONT SIDE ...

    FLIGHT-TIME: Place the ACRYL-TIPS of the NAVIMAT to START
    and GOAL on the MAP. Read DISTANCE in Kilometer on (A) or on
    (B) Nautical Miles. Under (C), refering to your Velocity,
    read FLIGHT-TIME.

    VELOCITY-OVER-GROUND: Between 2 remarkable Points on
    Ground, TAKE your FLIGHT-TIME. Set the ACRYL-TIPS of NAVIMAT
    to this 2 Points on Map. Find with the TAKEN-FLIGHT-TIME your
    VELOCITY-OVER-GROUND under (C).

             BACK SIDE ...

    COURSE: Put the ACRYL-ANGLE with PLANE (D) so on the Map,
    that the PLANE shows in the Course-Direction. TURN the OTHER
    ACRYL-ANGLE so, that its MIDDLE-LINE (E) is PARALLEL to a
    MAP's MEDIAN  A N D  the DEGREE-Figures are UPRIDE READABLE.
    Read on (F) the COURSE.

             BACK SIDE ...

    CALCULATION of VELOCITY-OVER-GROUND and LUV-ANGLE:
    Place the ACRYL-DIAGRAM with the PLANE-SYMBOL (H) ON COURSE.
    Place the WIND-ARROW-LAYER in WIND-DIRECTION. SLIDE the ACRYL-
    DIAGRAM in the COURSE-DIRECTION so, that VELOCITY (I) comes
    under the WIND-VELOCITY (J). Read on the same CROSS-POINT (K),
    the LUV-ANGLE. Over the MIDDLE-POINT of NAVIMAT read (L), your
    VELOCITY-OVER-GROUND.
