Flashcards in EFIS Deck (15):
What is EFIS?
Electronic flight information systems
Ambient light sensor
Functional elements of an EFIS system
What are the 3 main EFIS displays?
Engine and systems displays
What is PFD?
Primary flight display (PFD) replaces all primary flight instruments with a single combined display.
What is ND?
Navigation display (ND)
Plan view of A/C's horizontal nav situation
Can be overlaid with many diff types of info such as
What do engine and systems displays show?
Status of all A/C systems (on some A/C)
What is SID?
Standard Instrument dept (SID)
What is STAR?
Std terminal arrival (STAR)
These are predetermined arrival and departure routes
What's in Perf DB?
EFIS display architecture, what is the difference between dumb (1st gen), semi smart and integrated display architecture?
Dumb display use 2 sets of EFIS systems, with 1 additional stystem for back up.
Semi smart incorporated a graphics processor in each DU.
Integrated uses 1 EFIS system to supply data to the 2 sets of ND, PFD and Engine systems.
Some FMS have a nav mode called Dead Reckoning (DR), computing airspeed, HDG, wind data, GS and time. This mode is....
A back up nav mode to compute a FMS position when the other nav sensors are no longer operating.
DR mode is the default mode in the event of failure of the nav data input to some FMS
The FMS is approved to provide guidance for the following approaches:
Non precision approaches only
What is the source of magnetic variation info in a FMS system?
Mag variation in for is stored in each IRS memory it is applied to the ˚T HDG calculated by the respective IRS
Concerning FMS, entering a cost index of zero results in?
Max range airspeed
