During the exam the order of answers will be different.  \nReview questions:  \n1) Its good practice, when flying over large areas of water, that life jackets:  \na) Are worn, uninflated.  \nb) Should be carried under the pilots' seats.  \nc) Should be inspected periodically for leaks.  \nd) Are worn inflated.  \n2) A BCF fire extinguisher:  \na) Is quite safe to use in an enclosed cockpit if the cockpit is subsequently ventilated.  \nb) Gives off highly toxic fumes and should never be used in an enclosed cockpit  \nc) Is quite safe to use in an enclosed cockpit.  \nd) Is only suitable for wood or fabric fires and is, therefore, of no use in a cockpit  \n3) If you suspect carburettor icing when flying an aircraft whose engine is not fitted with a carburettor air-temperature gauge, the correct action would be:  \na) To always select full carburettor heat.  \nb) To select the appropriate amount of carburettor heat depending on the amount of icing suspected.  \nc) To always select full carburettor heat unless the engine starts to run roughly, at which point the carburettor heat should be selected to cold.  \nd) To open the throttle to make up for the lost power.  \n4) Aquaplaning speed:-  \na) Can be calculated, in knots, by multiplying the square root of the tyre pressure by nine.  \nb) Increases as the depth of tread on the tyres reduces.  \nc) Increases as the depth of water on the ground increases.  \nd) Is measured in miles per hour.  \n5) Connecting two 12 volt, 40 ampere-hour, capacity batteries in series will provide a battery of:  \na) 24 volts and 40 ampere-hours capacity.  \nb) 12 volts and 80 ampere-hours capacity.  \nc) 24 volts and 80 ampere-hours capacity.  \nd) 12 volts and 40 ampere hour’s capacity.  \n6) If a blockage occurs in the oil cooler of an aircraft engine while the aircraft is in flight, a by-pass valve allows the oil to by-pass the cooler. The by-pass functions on the principle of:  \na) Pressure dependence.  \nb) Temperature dependence.  \nc) Mechanical selection.  \nd) Hydraulic selection.  \nLatest information about the exam can be found [at](at www.cad.gov.rs/osoblje.php)[ ](at www.cad.gov.rs/osoblje.php)[www.cad.gov.rs/osoblje.php](at www.cad.gov.rs/osoblje.php) 2 / 27  \nPPL (A)– Aircraft general knowledge  \n7) A propeller blade is twisted along its length in order to:  \na) Maintain the optimal Angle of Attack from root to tip.  \nb) Give a progressively increasing blade angle from root to tip.  \nc) Give a progressively increasing pitch from root to tip.  \nd) Compensate for the decreasing linear speed of the blade from root to tip.  \n8) Magnetos are:  \na) Self contained, engine driven, electrical generators which produce high voltage sparks.  \nb) Generators, driven by the cam-shaft, used to supply electrical equipment  \nc) Used to generate low voltage sparks for the spark-plugs.  \nd) Fitted within the distributor, and fire in the same sequence as the spark-plugs.  \n9) Which of the following is an appropriate action to take if you have a carburettor fire on startup?  \na) Select mixture control to Idle Cut off (ICO) .  \nb) Deselect carburettor heat.  \nc) Turn the starter switch to \"Off\" .  \nd) AII of the above.  \n10) Tyre creep:-  \na) Can be recognised by the misalignment of markings painted on the tyre and the wheel.  \nb) Can be prevented by painting lines on the tyre and wheel.  \nc) Refers to the movement of an aircraft against the brakes.  \nd) Can be prevented with glue.  \n11) The diagram shows a light aircraft electrical power system. (See Fig. PPL AKG-1) In flight if the loadmeter reading drops to zero, the most probable cause is that the:  \na) Alternator has failed.  \nb) Battery has been fully charged.  \nc) Battery is flat.  \nd) Bus-bar is overloaded.  \n12) T","cbCaitLElrZSXES6","https://ap.wps.com/l/cbCaitLElrZSXES6","pdf",1881968,27,"English","# Review questions\n## Safety equipment and fire procedures\n## Engine and fuel/icing concepts\n## Aerodynamics and ground handling\n## Electrical systems and batteries\n## Propellers, ignition, and engine operation\n## Navigation, turning, and instruments","[{\"question\":\"What is the correct general knowledge action regarding life jackets when flying over large areas of water?\",\"answer\":\"Choose the option stating they are worn inflated (d).\"},{\"question\":\"How should carburettor icing be handled when there is no carburettor air-temperature gauge?\",\"answer\":\"Select the amount of carburettor heat based on the amount of icing suspected (b).\"},{\"question\":\"If the loadmeter reading drops to zero in flight on a light aircraft electrical power system, what is the most probable cause?\",\"answer\":\"The alternator has failed (a).\"}]","PPL (A) - Aircraft general knowledge | PDF",1790319528,68]
