Cruise power setting tables are useful when planning cross-country
flights. The table gives the correct cruise power
settings, as well as the fuel .ow and airspeed performance
numbers at that altitude and airspeed.

Sample Problem 7
Pressure Altitude at Cruise................................6,000 feet
OAT..................................................36 °F above standard
Refer to Figure 10-27 for this sample problem. First, locate
the pressure altitude of 6,000 feet on the far left side of the
table. Follow that line across to the far right side of the table
under the 20 °C (or 36 °F) column. At 6,000 feet, the rpm
setting of 2,450 will maintain 65 percent continuous power
at 21.0 "Hg with a fuel .ow rate of 11.5 gallons per hour and
airspeed of 161 knots.

Another type of cruise chart is a best power mixture range
graph. This graph gives the best range based on power
setting and altitude. Using Figure 10-28, find the range at
65 percent power with and without a reserve based on the
provided conditions.

Sample Problem 8
OAT.................................................................... Standard
Pressure Altitude............................................... 5,000 feet
First, move up the left side of the graph to 5,000 feet and
standard temperature. Follow the line straight across the
graph until it intersects the 65 percent line under both the
reserve and no reserve categories. Draw a line straight down
from both intersections to the bottom of the graph. At 65
percent power with a reserve, the range is approximately
522 miles. At 65 percent power with no reserve, the range
should be 581 miles. The last cruise chart referenced is a cruise performance graph.
