Manifold Pressure Values?????
in 912iS Technical Questions
9 years ago
I note that Rotax has released updated installation and operations manuals for the 912 IS and IS Sport.
However in the Performance section of the operators manual, unless I am mistaken, there is still no table of manifold pressures corresponding to recommended power settings at various rpm that would allow me to correctly set MP for my constant speed propeller.
I am required by law to refer to manifold pressures to set acceptable power levels.
While it may be possible to infer a power level from the supplied fuel consumption/manifold pressure graphs by assuming a g/kw relationship, this is not ideal and would not be approved data from a regulators perspective, nor does it indicate what operating rpm/manifold pressure ranges are desirable or permissible for the same power level.
Is this matter going to be addressed by Rotax?
