AIRPLANE
&
SYSTEMS
DESCRIPTIONS
-
The
airplane
is
delivered
from
the factory with corrosion preventive
oil
in the engine. This
oil
allows
fast
ring seating
and
should not
be
used
any
longer than
25
hours.
If
during the
first
25
hours
oil
must
be
added,
use only aviation grade
straight
mineral
oil
conforming to Specification
MIL-L-6082.
Refer to Section 8 for additional
oil
servicing information.
TURBO-SYSTEM
Each
engine
is
equipped with a turbocharger
and
related
components
to
allow takeoff
and
engine inoperative
power
to 12,000
feet
and
maximum
normal
operations
power
to 16,000
feet.
The
engines
work
and
act
just
like
any
normally aspirated engines;
how-
ever,
because the engines
are
turbocharged,
some
of the engine character-
istics
are different.
The
intent of
this
section
is
to point out
some
of
the items
that
are affected
by
turbocharging,
and
outline
the
correct
procedures to
be
followed.
For
a
better
understanding of the Turbo-System,
let
us
follow the induc-
tion
air
through the engine
until
it
is
expelled as exhaust gases. Refer-
ence should
be
made
to
the Turbo-System Schematic
shown
in Figure 7-23
when
reading
through
the following steps.
