same
line,
one
of
which
has
a
large
static
reservoir.
A
simple
remedy
for
this
problem
if
it
occurs
is
a
tee-‐fitting
near
the
static
port,
and
a
dedicated
line
to
the
instrument.
Obviously,
an
insufficiently-‐large
orifice
coupled
with
large
static
reservoirs
can
aggravate
the
problems
associated
with
lag.
The
pitot

MUST
be
connected
to
the

for
proper
operation.
RFI/EMI Considerations
The
instrument
is
shielded
and
does
not
generate
any
appreciable
level
of
electromagnetic
interference.
It
has
a
low-‐current
draw
and
cannot
contribute
to
RF
interference.
The
solid-‐
state
gyros
used
in
the
instrument
are
susceptible
to
outside
stray
RFI.
Be
sure
all
COM
antennas
are
properly
installed,
tuned,
and
grounded
as
stray
RFI
can
cause
unreliable
attitude
information.
