Since it climbs 197 feet, simply add 197 to -244 to get <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=-244%2B197=-47 ALIGN=MIDDLE  ALT=\"-244%2B197=-47\"   DISABLED_style= \"max-width:90%; height:auto;\" >. So after climbing 197 feet, the plane is still down 47 feet (from it's original height). Since it \"drops another 190 feet\", just subtract 190 from -47 to get <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=-47-190=-237 ALIGN=MIDDLE  ALT=\"-47-190=-237\"   DISABLED_style= \"max-width:90%; height:auto;\" >\r<BR>\n" );
