So, I've been noticing a weird behavior in the Mi-8. Often when at high speed, high power, and high-G maneuvers, I get a weird chirping sound, and then lose power to the radio altimeter, airspeed indicator, and gunsight. There may be other things losing problems, but these are the ones I see. The power comes back after a few seconds, but I'm wondering what I'm doing to cause these failures. I've tried checking to make sure my icing systems are off, to make sure I'm not drawing too much electrical power, but that doesn't seem to make a difference.
Also, on the icing panel, is up or down on? I haven't found a good explanation in the manual, though I haven't yet had time to read all of it.
