During the flight, you observe that what you saw as one return on your AWR screen, has now turned into two separate echoes. Which of the following statements is correct?
  • A
    The AWR is malfunctioning and the information cannot be trusted.
  • B
    This is a function that shows areas of CAT.
  • C
    This is due to unwanted returns from contamination on the radome.
  • D
    This is normal since with decreasing range the beam width azimuth will also decrease.

Refer to figure.

Airborne Weather Radar

For efficient target resolution, the beamwidth must be as narrow as possible, and with decreasing range the beam width azimuth will also decrease. As a result, two distant clouds might appear as one large return until, at a closer range, they are displayed correctly as separate entities.
