do you know what engine type is in those DA-40s? If it's a Thielert or Austro Diesel, you can abuse those throttles all day long as the FADEC will manage a lot of things including the acceleration of the engine.
Yes, this was a Lycoming powered DA-40 (I know the plane), so it was direct abuse. With the RED A-03 powered DHC-s Beaver I was test flying, jamming the power lever was one test element. Having more power than the P&W being replaced, I was not sure how the plane would handle the additional torque (which is also backwards). I sat on the grass, all set, both hands on the control wheel, and had a pilot friend I trust jam the power lever all the way up (knowing that I might tell him to urgently pull it off again), but it was fine, and the FADEC did limit engine acceleration. That said, I was witnessing fuel supply cut testing at the RED factory in May. We were testing (the previously untested) situation of the low pressure fuel is cut to one bank of the engine. The engine continued to run on the other bank during this test as per my test plan. When the fuel was returned to the deprived bank of the engine, it accelerated 500 RPM to max RPM (governed by FADEC) in 0.2 seconds - so brutally fast! We only did that test three times, for fear of damaging the dynomometer drive. The engine was okay with it, and MT propeller confirmed that if the engine had done it with a prop, the prop would survive. But, my RED A-03 power lever jamming is done!
on the old engines, there was the added potential entertainment value of a "rich cut" which would have been very embarrassing when starting to go-around after a PFL into some farmer's field or even on a standard go-around!
Yup! I was lent a Piper J2 on straight skis to do circuits on the frozen lake. I was warned to be easy on the throttle going around. I was not easy enough, so land back on the ice, and hand prop it out in the middle of the lake - outside the plane, by myself, standing on ice, with no way to secure the plane. I'm sure that the guys watching me from shore were very amused watching me learn a lesson!
When I was new right seat in the Cheyenne, my Captain admonished me a few times that the people in the back were paying a lot for the ride, make it smooth for them. After that, I aspired to fly silky smooth at all times.....
