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. In straight and level flight, the air flow over the wing's upper surface compared with the air flow unaffected by the wing Will have: the same velocity. a reduced velocity. a greater velocityWhen refuelling, to ensure that the correct type of fuel is used, both the fuel itself and tank labels are colour coded. The primary colour for all labels relating to 100ll is ….(i)… and the colour of the fuel itself should be …..(ii)….. i) blue ii) straw i) red ii) blue i) black ii) redWhat is the function of an idle cut off valve in a piston engined aeroplane? It inhibits fuel flow from the discharge nozzle in the carburettor when selected. It controls engine slow-running via the carburettor idle jet. changes fuel flow to the main jet from the idle jet when power is increased.When a magneto is selected OFF, the switch located in the primary circuit: is closed and the circuit is earthed is opened and the circuit is earthed is opened, breaking circuit continuity100 amp/hour battery will, in theory , supply 20 amps for up to: 5 hours. 3 hours. 4 hours.A VSI is a rate instrument that senses ...X... pressure which it then converts to a rate of change of ...Y... pressure, to indicate ...Z... speed. X : static Y : static Z : vertical X : total Y : pitot Z : vectorial X : pitot Y : pitot Z : verticalWhich of the following prevents excessive engine oil pressures? An oil pressure relief valve. A filter by-pass valve. A vernier thermAll aircraft have prescribed positive and negative 'G' load limits which form part of the Certificate of Airworthiness. If it is suspected that the positive 'G' load limit has been exceeded if only for a short period and by a small amount: no action is necessary as the maximum certificated loading limits are by design 20% below the value of structural failure. the aircraft commander should carry out a walk round inspection on landing and if satisfied with the structural integrity of the aircraft, take no further action primary structural damage or failure could have occurred and the aircraft must not be flown again until inspected by a qualified engineer.The percentage oxygen content of the atmosphere at higher altitudes compared to that at lower altitudes: decreases due to the decreased air pressure. falls, but since the quantity is adequate, the fall has little effect on the pilot at any altitude. remains constant, but the lower pressure makes it more difficult for the body to absorb oxygenA piston engine fuel/ air mixture ratio, ideally, should be in the region of: 1 :12 by weight. 1 :7 by weight. 1:9 by volume.Toxic carbon monoxide fumes that may enter a cockpit in the event of a heat exchanger malfunction: are not easily detected by either smell or sight ,as they are normally both odourless and colourless may be identified by their smoke-like appearance. may be identified by their strong pungent smell.After starting a cold engine, if the oil pressure gauge does not indicate within approximately 30 seconds: this may be ignored if the oil temperature is still low and the oil level was checked before start-up. the engine RPM should be increased and the oil pressure re-checked. the engine must be stopped immediately.you can go back for a final check or press SUBMIT to validate.
