    limiters

    im beginning to familiarize myself with the limiters. Im currently looking at the maximum engine output limiter. it has the 5 engine states on the rows and rpms on the columns. Im under the impression the 5 engine states are.

    0- transition
    1- low density
    2- low/med density
    3- med/high density
    4- high density

    is this correct?

    Basically looking at this map for example lets say 2000 rpm@ state 4 the maximum commanded fuel rate my engine will receive will be 125mm3, assuming their isn't another lower limiter.

    Reverse your 1-4 and you got it.

    0 - transient
    1 - high air density
    2 - med/high air density
    3 - med/low air density
    4 - low air density

    I was looking at my log and noticed I had a limiter pulling back some of my timing. And all it said was combustion manager. Any idea what direction I should look ?
