11.5 use other deck Flashcards
what are the 5 types of aircraft instrumentation
pressure, gyroscopic, compasses, mechanical, electronic
what are the classifications of instruments by use
flight, engine, navigation, other
what are the primary flight instruments
attitude, altitude, airspeed, direction of flight
what instruments make up the BASIC T
airspeed, attitude, altimeter, horizontal situation indicator
what is pressure
force differential by two points
what is the pressure and temp of the atmosphere
1013.25 hPa at 15 degrees celcius
what are the basic ways of measuring pressure
absolute pressure, gauge pressure, differential pressure
what can atmospheric pressure be measured in
InHg, hPa, PSI
what is the most common type of used pressure
gauge pressure
what is differential pressure
comparison between 2 different pressures
what do pressure sensors ensure
correct pressure readings
what are the 3 types of sensor used to measure fluid pressure
bourdon tube, aneroid capsule or bellows, pressure transducer
what does GA stand for
general aviation
what does an aneroid capsule do
compare absolute pressure to other pressures
what does a pressure transducer do
converts pressure into an analogue electrical signal
what does LDVT stand for (bourbon tubes use them)
linear variable differential transformer
what does a strain gauge measure
strain of an object
what are the 2 most common strain gauges
foil, silicon-based
what do pitot static systems ensure
ensures safe, efficient flight
what items need static pressure for their readings
altimeter, ASI, vertical speed indicator
what does the pitot pressure system measure
total pressure
whats a danger about the pitot tubes
they can become very hot
if an aircraft is parked for a long time what must be done with its pitot tubes
covered
whats inside a pitot tube to prevent foreign objects entering the pressure line
baffle
pitot and static pressures are transmitted though what material
seamless, corrosion resistant metals
if the pitot tube becomes blocked what will happen to the ASI reading
will become inaccurate
if the static ports became blocked what would happen to the ASI reading
would still function but is highly likely to be inaccurate
what are the 3 altimeter settings
QNH, QFE, QNE
what does QNH altimeter setting mean
sea level pressure
what does QFE altimeter setting mean
nearby surface airport
what does QNE altimeter setting mean
standard flight levels
what does an altimeter measure
pressure of surrounding air
what is altitude measured in
feet
whats the most common used altimeter
barometric
