The power off case would require more tail down force for same AOA. So, yes, like you say (this makes the plane "heavier"), higher IAS for same AOA. | |

| Apr 21, 2019 at 13:58 | comment | added | MikeY | You are talking about a Buckeye, correct? Saw your post on another forum. | |
| Apr 21, 2019 at 13:57 | comment | added | MikeY | Well then my swag would be that the Buckeye has a thrustline below the CG, so for the same speed but different thrust you have a different trim condition. Adding power leads to nosedown trim, and pulling it does the opposite. This would be an effect particular to the aircraft, not a general property. | |
| Apr 21, 2019 at 13:52 | comment | added | viper | Actual flight. Normally i execute the Slow Floght exercise at FL140, sometimes FL130. The numbers are a fact. I was prompted by the instructor to see the speed when climbing and diving. And explain to him why this happens. | |
| Apr 21, 2019 at 13:50 | comment | added | MikeY | Ok, are you actually in a real airplane, or a simulator? I’ve got a 1000 hours in Buckeyes, and you should see the same IAS for your cases. | |
| Apr 21, 2019 at 13:48 | comment | added | viper | i edited the original post trying to clear things up. Thank you for your help. | |
