NTS
On the 331 after shop visit a test is required to check the NTS RPM. This done to ensure the engine windmills above 28%. The target is 32% as I recall. This done by shutting off the fuel and watching the the NTS set the prop pitch to an angle that result in 32%. NTS does not govern or controlled at any speed just puts the prop in compromise position. To reduce drag until the pilots secures the engine. The test is conducted at ~6000 MSL and 160 kts.
