1-107 TEST ENGINE (AVIM) (Continued)
In the following step, SH!P required and % N2 were determined
in previous steps a. and b.
c. Using formula, Torque = (SHP required X 411), determine torque required.
d. Advance N1 master hydronic control until torque determined in preceding step c. is obtained.
e. Using water in master hydronic control, adjust load on engine until required N2 speed (step b.) is
f. Maintain maximum continuous power for 10 minutes. After 5 minutes have elapsed, take a full
g. Compare SHP and Wf recorded in step f. with SHP and Wf calculated in step a.
Actual SHP recorded in step f. shall compare with SHP calculated
in step a. within +50/ -0 SHP. Wf recorded in step f. shall not ex-
ceed Wf calculated in step a.
h. Retard N1 master hydronic control to ground idle (10 to 15 degrees).
i. Allow temperatures to stabilize; then shut down engine (Ref. Paragraph 21).
