All the above noted. I will do what I can to mitigate the shortcomings of the system on the 139 during training but as a sim instructor doing type ratings we don't normally get into the areas related to LOFT. When we do get around to doing recurrent training then we should get the opportunity to cover these problems and fully investigate the problem.
Nonetheless there will be some value in highlighting the best way of using the system and lessons learnt early on do tend to stick. (regrade switch etc).
I have to say that I have some serious issues with a set up that labels the rad alt test button "Decision Height" (the knob also changes the DH, shown on the PFD) and the associated radalt driven "Decision Height" visual cues on the Primary Flight Display. Can we get some movement on the evil concept that Rad Alt height can in any way be considered as a "Decision Height" - except when over water!
Meanwhile I sense a long road ahead for any changes.
