exm Flashcards
what axis is pitch controlled around
lateral axis
whats the purpose of vortex generators
re-energise a slow moving boundary layer
what are flaps used for
increase lift production during low speeds such as take off and landing
what does extending the trailing edge of the wing do
increases the camber to raise the lift co-efficient
what happens to the initial transonic shock wave when during transonic flight
moved all the way to the rear and has affixed to the aircrafts trailing edge
what are the advantages of using titanium on aircraft fuselages
titanium alloy can withstand higher temps whilst maintaining strength and shape
briefly describe semi monocoque (stressed skin) construction
skin reinforced by longitudinal members, also known as stressed skin structure
what are engine nacelles and their use
streamlined enclosures used primarily to house the engine and its components
what are the wing spars
principal structural members of the wing
before entering fuel tanks what must happen
fuel emptied and safety procedures must be followed
where are the ailerons attached
to the wing rear spar
what are spoilers attached using
bolts and bushes
where is pressurised air taken from in the engine
the entire compressor stage
what is the APU used for in the cabin
used to supply bleed air for air conditioning in the cabin
whats the function of the air conditioning system
maintain comfortable air temperature inside the aircraft
what temperature range is the cabin kept at
21-17 degrees celcius
what altitude does the cabin pressurisation help produce
8000ft or less
what is hypoxia
long periods at high altitudes causing fatigue and sickness
insufficient what causes hypoxia
oxygen
if the cabin altitude increases what happens to cabin pressure
cabin pressure decreases
what is in the basic T
airspeed indicator, attitude director indicator, altimeter, horizontal situation indicator
encoding altimeter
servo assisted altimeter
where are strainers in the reservoirs
in the filler neck
