And do you know what these pilots say when questioned why they did that? 'No one taught us how to read the graphs'
Yes - they look really complicated!
Regardless of the training, any TRE who uses a training mode without knowing how it works or how to calculate the performance limitations, probably shouldn't be in that seat.
Out of interest Epiphany, as a TRE on type, how quickly does the system exit training mode once 87% is reached, and is the recomended recovery from a low Nr situation to keep pulling? On the EC-155 and S-76C+ (which do actually place an engine in idle rather than simulating it) once the Nr hits it's lower limit (320 rpm on the EC-155) it doesn't budge any lower. The idling engine simply spools up and helps the driving engine. It's seamless and simple, but the only downside is that trainees don't realise they've mishandled the aircraft, because all they see is a nice gentle touchdown!
