Another example of quality training on that big cessna 172!
This really frustrates me as it's not hard to train people correctly and give them the tools to do a good job!
The moving red line is called the "dynamic red line" this is the maximum tq for take off up until 16000ft and then max climb power above that. The blue bug is Maximum cruise tq as per the cruise tq table in the POH. This cannot be relied on and needs to be confirmed by the PIC using the chart in the POH.
Max climb Tq is much much lower than take off tq and should be determined using the chart in the POH. Check out max tq for take off at 32'c sea level and then max climb tq at 32'c sea level and you will see what I mean.
The pt6-140 is not as forgiving as the pt6-114 and operators are going to have major problems if they do not follow these limits.
