purely CRM ... I fully agree with previous posts, now if the aircraft is single pilot just look on the top of your MFD
It just means ALT was not engaged, if it would have been engaged then they would have heard "ALTITUDE, ALTITUDE"
When ever you hear the chime, have a look if the mode is engaged (reverse video or not), Agusta should change the chime to 2 different chimes when engaged (or acquired) or disengaged, let's hope that will be part of the next software upgrade
The 139 is not that complex
, but if one organisation can afford a 139 but can't afford for 2 pilots to fly it then they have to think twice on what they want
