Glen: Aircraft Specification No. A-787 lists the following speeds for the
415-D:
Maneuvering 108
m.p.h (94 knots) True Ind.
Max structural
cruising 114
m.p.h. (99 knots) True Ind.
Never
exceed 144
m.p.h. (125 knots) True Ind.
This would put the yellow from 99 knots to 125
knots, with the red line at 125 knots. If you have the true D model
configuration (9 degrees up elevator), I personally would not put the green arc
any lower than 70 knots. If you have the C or CD configuration (13 degrees up
elevator), the green arc could go down to 60 knots. And if you have the E and
later configuration, I would say the green arc could go as low as 53
knots.
These green arc configurations are my personal
opinion, based on my experience flying the different models.
