Aw139 sar modes
G'day all
We have been utilizing the sar modes fairly extensively for about a year or so and a few little gremlins seem to pop up occasionally across all of our machines. A couple of examples:
1. When TU is engaged, the aircraft just "waffles" up and doesn't really accelerate. Normally, momentarily reengaging HOV (via the force trim release or trim switch) and then reselecting TU fixes the problem.
2. When passing through the fhaf on a mot and soon after path and decel are engaged, the fd occasionally just disconnects all modes without warning allowing the aircraft to continue to descend if left unchecked. The radalts both appear to remain functioning during this as well.
Usually these aren't too much of a big deal as long as things are being
monitored adequately but they certainly aren't ideal traits.
Has anyone had similar issues or is there something floating around addressing
similar issues? Thanks in advance.
