What is EFIS?

Electronic flight information systems

2

Data concentrator
Display Manager
Symbol generator
Display unit
Ambient light sensor

Make up?

Functional elements of an EFIS system

3

What are the 3 main EFIS displays?

PFD
ND
Engine and systems displays

4

What is PFD?

Primary flight display (PFD) replaces all primary flight instruments with a single combined display.


Shows:
ASI
VSI
HDG
Height
Attitude
Slip

5

What is ND?

Navigation display (ND)

Shows:
Moving map
Plan view of A/C's horizontal nav situation


Can be overlaid with many diff types of info such as
Wx
Radio beacons
Terrain
Waypoints
Aerodromes

6

What do engine and systems displays show?

Engine parameters
Status of all A/C systems (on some A/C)

7

What is SID?

Standard Instrument dept (SID)

8

What is STAR?

Std terminal arrival (STAR)

These are predetermined arrival and departure routes

9

What's in Perf DB?

123

10

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.

11

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

12

The FMS is approved to provide guidance for the following approaches:

Non precision approaches only

13

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

14

Concerning FMS, entering a cost index of zero results in?

Max range airspeed

15

The purpose of the ND is to display what info?

Flight plan
Wx radar
Terrain map
TCAS symbols
