    Altitude loss in a turn

    Rob,
    I have noticied I lose 100 ft or more while in a turn and once wings level altitude corrrects. Is this an adjustment for this?

    The Static Lag adjsutment in the AP can make this worse, you might try lowering it.

    Increasing the EFIS ALT gain should also help, if it gets too high it will overshoot when moving to the altitude bug.

    Rob,
    ALT GAIN currently set to 5.0 Static Lag set to 2
    What numbers do you suggest?

    Your only choice for the static lag is 0,1, or 2

    Did the static lag make any difference?

    How much are you losing?

    Do you have autotrim?

    Alan, what version of software do you have in the AP? What kind of bank angle are you seeing during turns?
