WARNING
Radar Energy is Potentially Hazardous
Aircraft weather radar is specifically designed to emit a concentrated
beam of microwave energy at potentially hazardous power levels.
These hazards include the possibility of injury to ground personnel,
ignition of flammable materials, including fuel, and damage to
sensitive electronic devices. The pilot in command is responsible for
management of the radar system.
The FAA has published an Advisory Circular, AC 20-68B,
Recommended Radiation Safety Precautions for Airborne Weather
Radar, with basic guidelines for safe radar operation.
U.S. Government standards for human exposure to microwave
radiation permit a maximum level of 10mW per square centimeter.
When the radar is operating, this level may be exceeded within the
area indicated in the figure below. According to information
published by the radar manufacturer, strict observance of this
boundary whenever the radar is operating should provide adequate
protection.
Exposure of ground personnel or other aircraft occupants to
microwave energy emitted at positions within the MPEL boundary
depicted below may be hazardous. Be aware that the MPEL
boundary is determined with respect to the antenna, not the radome
or any other aircraft structure. The MPEL boundary shown below
applies only to units specifically approved for use with the AeroNav.
The MPEL boundary shown below does not guarantee protection
against ignition of flammable materials or damage to sensitive
electronic equipment exposed to microwave energy from your radar.
