Hello. I am an IFR student (near the end- Last stage check of a Part
141).
I have a question about a DP.

The GATEWAY FOUR DP from CPS (E. St. Louis) has a note "For Turbojet
aircraft only".

Can this DP be used (voluntarily) for piston a/c? On this particular DP,
the
altitudes only call "Climb/Maintain 2500 or assigned. EFC to filed in 10
min." There are no similar DP for piston a/c.

I had been taught that if there is a DP that you can comply with, you
should
file it (i.e. GATWY4.BIB V12 ..etc).

Opinions?
