5-Which statement regarding aircraft and lightning is correct?

050 4267 Flight Hazards

An aircraft made by metal has a certain capacity to attract a lightning, but the lightning will follow the surface and therefore no damage will be caused. An aircraft has in the atmosphere the same qualities as a "Faradays cage", which means that struck of lightning seldom occurs. But if it happens, the result will be an occasional engine failure. The crew may get a shock. Aircraft made by composite material can't conduct a lightning and will therefore very seldom be struck. Aircraft made by composite material may get severe damage, the crew may be blinded and temporarily lose the hearing.

35-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.

48-Mark the statement most reasonable regarding a valley inversion.

050 16284 Flight Hazards

If the incident solar radiation is non-uniform because of orographic conditions, the development of a valley inversion is very likely during daytime. Small scale density variations due to turbulent mixing (mainly caused by the roughness of rocks) are a significant prerequisite for the formation of valley inversions. Provided that the lee side winds are able to displace the air at the bottom of the basin, the Foehn effect is the predominant factor in the development of a valley inversion. Over night, cool dense air as a result of radiation cooling will descend along the mountain slopes into the basin and lead to the development of a valley inversion.

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.

94-Mark the correct statement concerning the flight through an inversion caused by subsidence.

050 15859 Flight Hazards

During climb, the reduced air density above the inversion layer will cause a certain decrease in the aircraft performance (i.e. lift and thrust) and the pilot will experience a sudden improvement of visibility. The pilot of an aircraft probably will experience a gradual increase of the cross wind component and a gradual improvement of flight visibility when breaking through the base of the inversion layer during descent. During climb, the pilot of an aircraft probably will experience a slight deterioration of flight visibility when breaking through the top of the inversion layer and the general aircraft performance will decrease. During climb, the increased air density above the inversion layer will cause a certain increase in the aircraft performance (i.e. lift and thrust) and the pilot will experience a gradual change of the cross wind component.
