For operation on a dry, grass runway, increase distances (both “ground roll” and “total to clear 50 ft obstacle”) by 20% of the “total to clear 50 ft obstacle” figure. a combined landing distance graph and allows compensation Stall Speed Performance Charts for temperature, weight, headwinds, tailwinds, and varying Stall speed performance charts are designed to give an obstacle height. Begin by finding the correct OAT on the understanding of the speed at which the aircraft stalls in scale on the left side of the chart. Move up in a straight a given configuration. This type of chart typically takes line to the correct pressure altitude of 4,000 feet. From this into account the angle of bank, the position of the gear and intersection, move straight across to the first dark reference flaps, and the throttle position. Use Figure 11-34 and the line. Follow the lines in the same diagonal fashion until the accompanying conditions to find the speed at which the correct landing weight is reached. At 2,400 pounds, continue airplane stalls. in a straight line across to the second dark reference line. Once again, draw a line in a diagonal manner to the correct Sample Problem 13 wind component and then straight across to the third dark Power........................................................................

From this point, draw a line in two separate directions: one straight across to figure the ground roll and Flaps.......................................................................

First, locate the correct flap and gear configuration. The bottom half of the chart should be used since the gear and
