PPL - Aircraft General Knowledge The test consists of 12 questions. You are given 25 minutes to complete. To pass you need to score 75% Login or personal details are not required. 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. When compared with perfectly dry air at the same temperature and pressure, air which contains a maximum amount of water vapour will have a similar density lower density greater densityWheel spats that have become heavily contaminated with soil and grass: are designed to be cleared by wheel rotation. must be removed, cleaned and freed of all contamination and re-fitted before the next flight. must be discarded before the next flight.The use of take-off flap will result in: greater acceleration. icreased rate of climb to transition altitude. a shorter take-off run.An aircraft that has been overstressed: must be inspected by a qualified engineer before the next flight. must be inspected by the pilot in command and if no defect is found, s/he will not be required to make an appropriate entry in the aircraft technical log. must be inspected by at least two pilots licensed on the type, one of whom must be the pilot in command.The International Standard atmosphere assumes that the ambient temperature: increases with increase in height above the Earth will decrease with height only if an inversion layer is present. decreases with increase in height above the Earth.A piston engine fuel/ air mixture ratio, ideally, should be in the region of: 1 :7 by weight. 1:9 by volume. 1 :12 by weight.If the appropriate manual or check list is not available to deal with an engine fire during flight, you should: make a May Day call, slip the aircraft to keep the fumes away from the cabin, then attempt to put the fire out using the cabin fire extinguisher. close the throttle, turn the fuel off and close the cabin air intake. close the throttle, switch off the ignition, then set up for a forced landing.Two 12 volt 40 ampere-hour capacity batteries connected in series would result in a total capacity of: 20 ampere-hours at 24 volts. 80 ampere-hours at 12 volts. 40 ampere-hours at 24 volts.A stalling angle of attack is increased by 'slots' because: they dump positive pressure airflow from under the wing. they delay the break up of the smooth airflow over the wing. they increase the effective wing area at the leading edge.A flying Control lock: locks controls in flight to neutralise aerodynamic loads and ease the physical load on the pilot. locks the trim tabs once straight and level cruise is established. locks controls on the ground! to prevent damage in windy conditions.High cylinder head temperatures can be reduced by: reducing power and airspeed. closing the cowl flaps which will increase the cooling airflow over the engine. enriching the fuel/ air mixture to reduce combustion chamber temperature.The centre of pressure by design is behind the aircraft centre of gravity which is balanced in straight and level flight by: the tail plane producing an upward force. the tail plane producing a downward force. neither an upward or down ward tail plane force as the aircraft will be in equilibriumyou can go back for a final check or press SUBMIT to validate.
