A thalweg is ? Test > UAV An area of lower atmospheric pressure than surrounding regions. On a weather chart a Low a depression is represented by ? On a weather chart a low a depression represented Closed isobars with pressure values increasing from center to outside. A so called 'ridge' is ? A so called 'ridge' A ridge of high pressure. A front a Narrow transition zone between two air masses. A cold front Moves faster than a warm front. In northern hemisphere winds blow Clockwise around a high pressure area counter clockwise around a low pressure area. During passage of a cold front Warm air lifted as colder air pushes under it. Question 52-8 The following sequence of clouds observed at an airport cirrus altostratus nimbostratus the observer should expect The passage of a warm front. Question 52-9 The part of a frontal system along which cold air retreating called The passage of a warm front. Question 52-10 Name front associated with progression of following clouds cirrus cirrostratus altostratus and nimbostratus The passage of a warm front. Question 52-11 What the term that best describes high pressure The passage of a warm front. Question 52-12 Airframe icing results in A loss of aerodynamic performance of aircraft. Question 52-13 Airframe icing in flight Can be a potentially very dangerous phenomenon. Question 52-14 One of possible consequences of airframe icing The degradation of aerodynamic profiles. Question 52-15 If ice has accumulated on an aerofoil in flight stalling speed will Increase in all flight conditions. Exclusive rights reserved.
