PC24 Engine ‘APU mode’

Anyone have more information on this unusual
system ?


I understand this Pilatus doesn’t have a dedicated
APU but one engine has been modified to
operate continuously at, I believe a different
idle speed supplying electrical and pneumatic?
power


I know some turboprops have this feature
but I’ve never seen it on a jet

It would seem an advantage to not have to carry
around the weight of a separate APU not to mention the lower
cost but does it do the same job and what about the extra hours
you are putting on that engine ?
