1. INTRODUCTION
This section contains instructions and data for testing engines after maintenance to determine engine flight
readiness, using mobile trailer assembly.
a. Graph Reading. To read any of the graphs presented in this section, locate the applicable unit at the
bottom of the graph, project vertically from this unit to the level that intercepts the required curve line;
then read the results given at the left. Definitions for curves on the graphs are:
(1) Maximum Power is the maximum power the engine will consistently deliver at specified ground or
flight conditions for an incremental duration of 10 minutes.
(2) Intermediate Power is the highest power which the engine will consistently deliver at specific ground
or flight conditions for an incremental duration of at least 30 minutes, and a total duration as specified
for demonstration during qualification tests or preliminary flight rating tests.
