Question 2

2. What is the input source/s for the command speed display on the PFD?

Answer 2

a. Airspeed set in the MCP IAS/Mach window

b. FMC computed speed when window is blank (AOM 10-2)

Question 3

3. What identifies the active way point on the ND?

Answer 3

a. It is named in the top right corner of the screen (AOM 10-64)

Question 4

4. The altitude range arc (‘green arc”) displays what information?

Answer 4

a. Position where MCP altitude will be reached based on vertical and ground speed (AOM 10-69)

Question 5

5. The WXR, STA, WPT, ARPT, DATA, POS, TERR switches on the EFIS control panel display what information when pushed (each individually)?

Answer 5

a. WXR - Powers radar transceivers selected on wx radar control panel
b. STA - Displays high/low VORs when ND range is in 40nm or less and High VORs when ND
range is over 40nm
c. WPT – In MAP and MAP CTR Modes displays waypoints when ND range selector is 40nm or less
d. ARPT - In MAP and MAP CTR Modes displays airports in all ranges that have runways at least 6000’.
e. DATA - In PLAN, MAP and MAP CTR Modes displays FMC ETA Altitude at each waypoint and altitude constraints at each waypoint
f. POS - In MAP/MAP CTR Modes – Displays your where the GPSs, IRUs, and turned VORs think you are located. Also tells you what your most accurate navigation source is. When collocated DME data is received, tick mark display at DME distance. Radial extends to edge of display if no valid DME data received.
g. TERR - Activates GPWS Look-Ahead terrain mode (AOM 10-29)

10. When will the G/S and LOC indicators/scales display and when will they fill to a solid
    magenta?

Answer 10

a. Both indicators display when frequency is tuned and fills in solid when within 2 1/3 dots from the center (AOM 10-9, 10)
