(a) Idle Test
Using the air turbine starter (about 60. HZ'? at
369000 -,38#000 rpm) developed at Zavod No.2, it
took 80-90 seconds to bring the engine up to the
idle point of 3500 rpmo All the, instruments were
checked; noises, vibrations and any leaks were
noted. The fuel. was then turned aef and the ?follow-
