What does the term permeability mean with respect to magnestism? - all answers
The most common type of pump used to power the flight instruments (attitude indicator
and heading indicator) in the modern general aviation aircraft today is the wet vacuum
pump. - FALSE
The de-ice fluid by airlines, which one is the most expensive but has the longest hold-
over times. - Type IV
The most commonly used de-ice fluid by airlines and the least expensive. - Type I
In a situation where the engine power is set for takeoff, on a constant speed propeller
powered aircraft the air through the intake system is moving at high velocity, creating
friction and drag as it also encounters the bends and skin friction of the intake system. A
typical engine intake system will lose 7-8 inches of ambient pressure at take-off RMP
and full throttle. - FALSE
Most normally aspirated reciprocating engines in general aviation are designed to
produce continuous power with economical operations and promote long engine life at
continuous cruise settings of 90% of their sea level rated power. - False
To avoid momentary high cylinder head pressures and internal stresses, the pilot should
always keep RPM higher when reducing power, by reducing MAP first. - TRUE
When making power increases in aircraft with MAP and RPM controls, the pilot. first
moves the RPM higher than the MAP. A good habit to get into is to work from right to
left across the power quadrant when increasing power. - TRUE
Aircraft magnetos provide a good hot spark at idle, cruise and at high speeds, but some
provision must be made for getting a hot spark when the engine first turns over slowly
while starting. This spark is provided by the impulse-coupler. - TRUE
When the throttle (constant speed prop/normally aspirated engine) is opened fully for
takeoff, the large pressure drop across the throttle is removed, so MAP will rise to
nearly equal the ambient pressure minus any friction and other losses within the intake
manifold. - TRUE
, Superchargers are usually built internally within the engine and are powered by
mechanical gears driven off the crankshaft. Supercharger installations are most often
found in high horse power radial engines. - TRUE
Turbochargers are designed to deliver compressed air to the inlet of the carburetor or
fuel/air control unit of an engine. They derive their power from the energy of engine
exhaust gases directed against some of the turbines. - TRUE
The waste gate valve of the turbocharger, controls the volume of the exhaust gas that is
directed onto the turbine rotor and thereby regulates the speed of the turbine rotor and
the speed of the compressor/impeller and thus the increase in induction pressure to the
engine. - TRUE
According to our textbook, manual waste gate control on turbocharged engines is
normally found on general aviation aircraft manufactured as original equipment on new
aircraft direct from the factory. - FALSE
The main purpose of supercharging/turbocharging an aircraft engine is to increase MAP
above the pressure of the atmosphere in order to provide maximum high power for
takeoff and sustain maximum power during climb and cruise at higher altitude. - TRUE
Regarding turbochargers, when the waste gate it completely closed, critical altitude for a
particular MAP setting has been reached. Further climb will result in a reduction of MAP
as the turbocharger isn't able to produce enough boost differential pressure. from the
thin air above critical altitude. - TRUE
In regards to turbocharger systems, the differential pressure controller regulates the
position of the wastegate valve to maintain. a setting which prevents/limits the deck
pressure within the aircraft induction manifold, to prevent overboosting, because of
excessive MAP. - FALSe
Today's modern automatic turbocharger systems usually utilize a density controller and
a differential pressure controller to regulate the wastegate positions between the full
open and closed. - TRUE
An overshoot is a condition which manifold pressure far exceeds the limits for a given
RPM prescribed for a particular engine operation and can cause serious damage to the
turbocharged engine - FALSE
Air in certain turbocharged inductions systems is cooled by an intercooler, co called
because it cools the air after compression thus making it denser. without decreasing
pressure and eliminating problems associated with too hot a fuel/air mixture - TRUE
Static discharge wicks found on aircraft structures such as the wing and tail surfaces
are designed to prevent the aircraft from being stuck by lightning strikes. - False
