STATIC DISCHARGERS
As an aid in IFR flights, wick-type static dischargers are installed to
improve radio communications during flight through dust or various
forms of precipitation (rain, snow or ice crystals). Under precipitation
static (P-Static) conditions, the build-up and discharge of static
electricity from the trailing edges of the wings, rudder, elevator,
propeller tips, and radio antennas can result in loss of usable radio
signals on all communications and navigation radio equipment. Usually
the ADF is first to be affected and VHF communication equipment is the
last to be affected.
Installation of static dischargers reduces interference from P-Static, but
it is possible to encounter severe P-Static conditions which might cause
the loss of radio signals, even with static dischargers installed.
Whenever possible, avoid known severe precipitation areas to prevent
loss of dependable radio signals. If avoidance is impractical, minimize
airspeed and anticipate temporary loss of radio signals while in these
areas.
Static dischargers lose their effectiveness with age, and therefore,
should be checked periodically (at least at every annual inspection) by
qualified avionics technicians, etc. If testing equipment is not available,
it is recommended that the wicks be replaced every two years,
especially if the airplane is operated frequently in IFR conditions. The
discharger wicks are designed to unscrew from their mounting bases to
facilitate replacement.
12 VDC POWER OUTLET
A power converter, located below the copilot seat, reduces the
airplane's 28 VDC power to 12 VDC. This converter provides up to 10
amps of power to operate portable devices such as notebook computer
and audio players. The power output connector (POWER OUTLET
12V) is located on the center pedestal, refer to Figure 7-2, Instrument
Panel.
