CLEAR ALL DISCHARGE POINTS
Clearing the discharge points periodically while you are monitoring thun-
derstorms is a good way to determine if the storm is building or dissi-
pating. Discharge points in a building storm will reappear faster and in
larger numbers. Discharge points in a dissipating storm will appear
slower and in smaller numbers. To clear the discharge points, press the
CLEAR key on the KMD 150. Alternatively, if an optional remote clear
button has been fitted, press that.
SWITCH BETWEEN WEATHER VIEWS
The KMD 150 can display the Stormscope data in one of two views,
either all round (360°) or forward looking only (120°). To switch the dis-
play between weather views simply move the joystick up and down.
Note that when switching between weather views, the range remains
SWITCH BETWEEN WX DISPLAY MODES
As detailed in the introduction to this section, the KMD 150 can display
the Stormscope data in one of two modes, either Cell Mode or Strike
Mode. To switch the display between modes simply move the joystick
left and right. The currently selected weather display mode is indicated
on the top left of the screen and will toggle between CELL and STRIKE
with each press of the joystick. The mode selected here will remain in
effect until you change it, even if the unit is turned off and back on.
CHANGING DISPLAY RANGE
To change the displayed range of the Stormscope screen, press either
the Zoom In or the Zoom Out keys. With each press of the zoom keys,
the screen changes to display the electrical discharge activity detected
within the new range. The range indicator will also change to display the
numerical value of the new range (25, 50, 100, or 200 nm). This new
range corresponds to the distance from the aircraft to the outer range
ring on the screen.
Your KMD 150 stores electrical discharge information for all ranges
simultaneously to provide you
electrical discharge activity when you select a new range.
As you move from one range to the next, the 25 nm range is always indi-
cated by a solid ring to advise you of your close proximity to thunder-
storms. You may also notice that the discharge points are progressively
larger on the shorter ranges and smaller on the longer ranges. This
effect makes it easier to spot clusters of discharge points in any range.
