Should you desire to download a Certificate of Accomplishment if you pass, do not forget to fill your name (as you want it written on the Certificate), at the end of the quiz. Spark plugs receive their high tension supply from: the alternator. a magneto, independent of the A/C electrical system. a magneto supplied from the A/C electrical system.Induced Drag: is increased as airspeed increases is reduced as airspeed increases is not a factor of airspeed.Air density reduces with altitude because: the pressure falls. the temperature falls. of the fall in water vapour content.The type of gas that is stored in a small cylinder attached to a life jacket and used to inflate the life jacket is: helium air. carbon dioxide.The restrictive throat of a carburettor venturi changes the characteristics of the air that passes through it. These are: a drop in ambient pressure and velocity increase. a dynamic pressure decrease and a velocity increase. a dynamic pressure increase and a velocity decrease.The operation of a mechanically steered nose wheel is normally accomplished by: cables connected to the aileron control wheel. push-pull control rods and/or cables operated by the rudder pedals. the use of differential braking technique.The angle of attack of an aerofoil may be defined as: the angle subtended by the aerofoil chord line and the relative airflow. the angle subtended by the aerofoil chord line and the longitudinal axis. the angle subtended by the aerofoil mean chord line and the horizontal.Carbon monoxide gas is highly toxic. Should a leak occur in the exhaust/air heat exchanger allowing carbon monoxide to enter the aircraft cabin: it may be identified by its strong smell. it may be identified because of its grey colour. it cannot be detected because it is both odourless and colourless.Water based fire extinguishers are most effective when extinguishing burning electrical equipment and acids. fossil fuels and oils. paper and furnishing fabrics.Complete the following statement.
