Hi
Some questions RE the CSU, preferably in a Cessna 172RG
1. How/can a pilot select a setting, ie: MAP, RPM, etc., that will provide the angle of attack which produces the best thrust/torque propeller ratio in a similar way to how an IAS is designated for the best lift/drag ratio, eg: the POH's performance charts?
2. Once the aircraft levels out in cruise, & a particular RPM is set, under what conditions (eg: climb, descent, other?) would the TAS increase or decrease significantly (thereby changing blade angle), for the purposes of proving to the textbook student that the prop's most efficient angle of attack is preserved?
3. From it's very definition, Constant Speed Unit, can you please confirm that it's the prop RPM & not engine RPM that's been maintained?
Sorry if the questions we're too confusing.
Cheers
Ben
