7-Which of the following statements regarding the development of valley inversions is correct?

050 15032 Flight Hazards

The predominant factor in the development process of valley inversions is the non-uniformity of incident solar radiation due to orographic conditions in combination with density variations within the air. The most important prerequisite for the development of valley inversions is warm air ascending along the mountain slope, thus leaving cooler air behind in the bottom of the valley. Usually a valley inversion is initiated by radiation cooling and anabatic winds which are due to orographic conditions. Valley inversions often are a result of radiation cooling in combination with gravity, both affecting the air at the surface of a mountain slope.

23-Which of the following statements regarding an aircraft being struck by lightning is true?

050 16788 Flight Hazards

The crew of an aircraft made of conductive material (e.g. metal) will generally suffer greater adverse effects due to lightning discharge than the crew of an aircraft made of non-conductive composite material. The dimension of the damage caused by the lightning stroke is reciprocally proportional to the strength of the electric field the aircraft intruded. The flight crew might have temporary difficulties in determining the current attitude of flight. Though flying through an electric field, the aircraft itself is not a charge carrier and therefore it cannot initiate a lightning discharge.

050 14897 Meteorological Information

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.

95-While using the airborne weather radar in order to circumnavigate thunderstorms, the radar scope is clear between heavy echoes.
Which of the following interpretations of the scope is correct?

050 16778 Flight Hazards

The clear area indicates an area from which no echoes are received because the number of cloud droplets is too small to generate a significant echo. Thus, the pilot will have a good visual sight of the thunderstorm clouds. The clear area indicates an area from which no echoes are received. An aircraft flying in this area will be in VMC due to the absence of precipitation drops. This is a typical radar scope from which the region of clear air turbulence between thunderstorm clouds can be detected. The clear area indicates an area from which no echoes are received. However, this radar scope provides no assurance of being in VMC while flying in this area.
