Narrative:
While on approach to runway 17 at evy, I had to deviate from my approach because a cessna was approaching from base at a steep angle and didn't appear to have me in sight. He was about 200 ft to my left and about 100 ft higher and didn't appear to have us in sight and was making no move to change his flight path. He was performing a high overhead simulated engine failure and I don't think his descent angle ever exposed our position. I was flying a heavy helicopter and if he had landed behind me our rotor wash would have caused control problems for him, so I deviated to another runway.
