HOW TO USE THE GRAPHS

1. In addition to presenting the answer for a particular set of
conditions, the example on the graph also presents the
order in which the various scales on the graph should be
used. For instance, if the first item in the example is
OAT, then enter the graph at the known OAT and pro-
ceed to the remaining item(s) in the order given in the
example.
2. The reference lines indicate where to begin following the
guidelines. Always project to the reference line first, then
follow the guidelines to the next known item by maintain-
ing the same PROPORTIONAL DISTANCE between the
guideline above and guideline below the projected line.
For instance, if the projected line intersects the reference
line in the ratio of 30% down/70% up between the guide-
lines, then maintain this same 30%/70% relationship
between the guidelines all the way to the next known
item or answer.
3. The associated conditions define the specific conditions
from which performance parameters have been deter-
mined. They are not intended to be used as instructions;
however, performance values determined from charts
can only be achieved if the specified conditions exist.
4. Indicated airspeeds (IAS) were obtained by using the
AIRSPEED CALIBRATION-NORMAL SYSTEM graph.
5. The full amount of usable fuel is available for all
approved flight conditions.
