`The test program demonstrated that successful and rapid forwardto reversethrust transients can be
`performed without any significant engine operational limitations for fan blade pitch changes through either
`feather pitch or flat pitch. For throughfeatherpitch operation with a flight inlet, fan stall problems were
`encountered, and a fan blade overshoot technique was used to establish reverse thrust.
