Figure 11-25.  Fuel, time, and distance climb chart.  First, find the information for the departing airport. Find the  OAT for the departing airport along the bottom, left side of the  graph. Follow the line from 25 °C straight up until it intersects  the line corresponding to the pressure altitude of 6,000 feet.  Continue this line straight across until it intersects all three  lines for fuel, time, and distance. Draw a line straight down  from the intersection of altitude and fuel, altitude and time, and  a third line at altitude and distance. It should read three and  one-half gallons of fuel, 6 minutes of time, and nine NM. Next,  repeat the steps to find the information for the cruise altitude.  It should read six gallons of fuel, 10.5 minutes of time, and  15 NM. Take each set of numbers for fuel, time, and distance  and subtract them from one another (6.0 – 3.5 = 2.5 gallons of  fuel). It takes two and one-half gallons of fuel and 4 minutes  of time to climb to 10,000 feet. During that climb, the distance  covered is six NM. Remember, according to the notes at the  top of the chart, these numbers do not take into account wind,  and it is assumed maximum continuous power is being used.  The next example is a fuel, time, and distance-to-climb table.  For this table, use the same basic criteria as for the previous  chart. However, it is necessary to figure the information in a  different manner. Refer to  Figure 11-26  to work the following  sample problem.  To begin, find the given weight of 3,400 in the first column of  the chart. Move across to the pressure altitude column to find  the sea level altitude numbers. At sea level, the numbers read  zero. Next, read the line that corresponds with the cruising  altitude of 8,000 feet. Normally, a pilot would subtract these  Figure 11-26.
