| The antenna tilt shall be adjusted in order to receive the most significant echoes (generally received from an altitude of approximately 30000 ft). |
| Accurate assessment of the weather ahead of the aircraft might be hampered due to the attenuation of the radar echoes by heavy rain. |
| The most significant echoes will be received due to lightning discharges near the freezing level. |
| The radar reflectivity echoes are much more determined by the number of reflecting particles than by the particle size. |
