I have a unique issue…when i takeoff and say put my VS at 1400 (any random number), the next thing I do is try to set the cruising altitude. At this point most often than not, my plane makes a sudden dip (around 300-400VS) before returning to 1400 (or any VS set). Mostly this happens below FL100 and the effect reduces when I set it after FL110+
Am I missing something here?
Any help would be appreciated.
