Regulator Trim
Regulator Trim
(OP)
Really basic question here: can someone please explain what "trim" refers to with regards to regulators? And, is it the same as the percent capacity?

RE: Regulator Trim
Can you give examples of what these goodies are tho? & does this mean that it DOES affect the capacity & therefore is also expressed as %capacity (instead of % trim)?

RE: Regulator Trim
so how is the capacity determined from using different internals? that is, how do you determine the trim level (70%,80% or 100%) if you replace a part with a different part?? or how is that trim level number determined in the first place??

RE: Regulator Trim
trim level = %trim = %capacity
check out this spec sheet for a mooney regulator:

in the bottom right corner are varying Cg's based on the level of trim or %capacity. does anyone know how this level is determined?

If you look at the little graph,
htt
you will see that there is one of two springs that you can select. Since each spring has a different spring constant, the percent open would be different for each spring at the same capacity, therefore (apparently) it made more sense for them to relate Cv to %Capacity rather than to %O. The typical method of showing Cv to %O would require two graphs, one for each spring.
