1In the U.S. 80% of tonadoes are produced by?
supercell thunderstorms
2The decrease of the intensity of energy within the radar beam due to absorption or scattering of the energy from precipitation particles. Because of this distant targets (i.e., precipitation) behind of nearer target may not be displayed on a radar image. This is called as:
precipitation attenuation,
3BL Which is recommended procedures when if a pilot entered in an embedded thunderstorm unintentionally?
Attempt to maintain a level flight attitude and set power for recommended turbulence penetration airspeed (VB)
4Select the radar abnormalities that reflect lesser energy
liquid cloud-sized particles
5Anomalous Progagation (AP) is?
When ducting occurs, the radar beam will hit the surface of the Earth, causing some of the beam's energy to backscatter.
6BL if the aircraft weather radar shows intensive thunderstorm echoes, this echoes should be circumnavigated by maintaining a minimum distance of
20 miles
7Select correct statement
Ground radar has more power output which allows for better detection of low reflectivity (small) targets in the atmosphere, such as clouds, dust, insects, etc.
8the ability of the radar to identify targets separately (large ground radar is better at the same range) is called:
Beam resolution
9How the weather radar (either ground or airborne - not a doppler radar) detect a target?
by sensing reflective energy.
10BL If a cumulonimbus cell is located on your route of flight, a pilot should
A. circumnavigate the cell keeping the distance laterally by at least 20 NM.
