GWX 68 Installation Manual

Preliminary Revision 1

GENERAL PRECAUTIONS

Airborne weather radar should be operated on the ground only by qualified personnel.

Installed airborne radar should not be operated while the aircraft is in a hanger or other enclosure unless
the radar transmitter is not operating, or the energy is directed toward an absorption shield which
dissipates the radio frequency energy.  Otherwise, radiation within the enclosure can be reflected
throughout the area.

BODY DAMAGE

To prevent possible human body damage, the following precautions should be taken:

1.

 

Personnel should never stand nearby and in front of a radar antenna which is transmitting.  When the
antenna is not scanning, the danger increases.

2.

 

The recommended safe distance which is established above should be followed.  The distance from
any person to the radar should be greater than that distance.

3.

 

Personnel should be advised to avoid the end of an open waveguide unless the radar is turned off.

4.

 

Personnel should be advised to avoid looking into a waveguide, or into the open end of a coaxial
connector or line connector to a radar transmitter output, as severe eye damage may result.

5.

 

Personnel should be advised that when high power radar transmitters are operated out of their
protective cases, X-rays may be emitted.  Stray X-rays may emanate from the glass envelope type
pulser, oscillator, clipper, or rectifier tubes, as well as magnetrons.

COMBUSTIBLE MATERIALS

To prevent possible fuel ignition, an installed airborne weather radar should not be operated while an
aircraft is being refueled or defueled.
