PUDSUC – 口訣 : pitot static blockages
August 4, 2024
Reference: Instrument failure: the test of trust | Flight Safety Australia PUDSUC A pitot blockage will cause airspeed to underread on descent (vice versa on climb). A static blockage will cause airspeed to underread on climb (vice versa on descent).
[GA piston engine] What’s full throttle height?
August 3, 2024
Full throttle height – Depending on the power setting, as an aircraft climbs (fitted with a fixed-pitch propeller), a height is reached eventually where the throttle will be fully open to maintain that power setting. Important concept: An aicraft can have various power setting! Each power setting has a full-throttle height! Read more
[GA Piston Engine] Effect of Increasing Height on Power Output
August 3, 2024
(On a ‘standard’ day) Aicraft climbs / fly high –> output of the engine decreases for two reasons: decrease in atmospheric pressure – reduces the manifold pressure and thus the flow of air into the cylinders (a similar effect to closing the throttle) – can be compensated for by progressively opening the throttle decrease in
Too lean, Too rich, CCM, Best power, Best economy
August 3, 2024
Notes: The carburettor measures the weight of air passing through the induction manifold and uses this measurement to regulate the amount of fuel discharged into the air stream (according to a predetermined schedule). What’s rich, lean and CCM? Rich: 1:8 Chemically Correct fuel/air Mixture (CCM): 1:15 Lean: 1:20 In theory, the ‘correct’ quantity

Static wick Static wicks, also called static dischargers or static discharge wicks, are devices used to remove static electricity from aircraft in flight. They take the form of small sticks pointing backwards from the wings, and are fitted on almost all civilian aircraft.
