Head Up Displays Flashcards
Adavatages
~incraese situation awerness
~improved accuracy of flying
~reduced suspeptibility to eneter a undersired a/c state
Disadvantages:
During high woorkload periods of fligght,where over looking it can distract
~ a computer to receive a/c data and generate display symbolgy
~an overhead unit to mout the cathode ray tube which projects the assemble image onto
~the transparent display screen called a COMBINER
~a control panel to allow selction by the pilot
~an annunciator panel
DGC (display guidance computer)
Generates the symbol imagenery for the HUD
provides the required flight instrumention and information selcted by the pilot
Display controller
~DECLUTTER is the pilots abilty to improve see through capabilty of the HUD
Combiner
Can be flat or concave ,has. A syntethic hologram coating allowing the display to appear clary whilst allowing the light from outside to pass throught it
~a built in ambient light sensor maintains the set brightness kevel
T
~decluttermode removes the baro alt ribbon and speen ribbon
~declutter can be automatic orselcted by the pilot
~flight paramenters are replaced by numerical values
Waring
Tcas
Confromal dsipaly data
~the boreseight or waterline symbol :reference symbol that shows where the nose of the a/c is actually pointing
~the flight path vector :a symbol which shows where the a/c is actually going
~runway symbol: on approach whe nbelow 325 agl the runway symbol appears on the display aligned to the actual runway
SVS/EVS
Sysnthetic/enhance visual syste,
~infared cameras ,uses temperature difference for image
~externa; sensors
