Navigation/Communication

Question 1

Describe the amplified procedure for Radios and Navaids set during the Before Start Check?

Answer 1

Set navigation and communication equipment for departure. Ensure navigation equipment is set in a manner that will allow a timely transition to conventional navigation methods in the event of an FMS malfunction.

Question 2

List the pages of the RMU?

Answer 2

PGE Menu allows for selection of the various RMU pages:
– Com Memory 
– Nav Memory 
– ATC/TCAS
– Navigation
– Engine
– Sys Select
– Maintenance
   • Ground only

Question 3

How can COM 3 be selected for communication?

Answer 3

RMU Pages - Sys Select, then choose pairing.

Question 4

What is the function of the EMER selection on the Digital Audio Panel (DAP)?

Answer 4

Disables the interphone and isolates the flightcrew by connecting the Captain directly to COM 1 and NAV 1 and the First Officer directly to COM 2 and NAV 2. ACM radio communication capability is lost.

Question 5

What is the purpose of the Tuning Backup Control Head (TBCH)?

Answer 5

Provides alternate means of tuning COM 2 and NAV 2.

Question 6

Will the Tuning Backup Control Head (TBCH) remain powered in essential power?

Answer 6

No, it is powered by DC Bus 2.

Question 7

How can the weather radar be brought out of FSBY on the ground?

Answer 7

The weather radar is in forced standby mode while on the ground. This forced standby mode may be overridden by pushing the STAB button 4 times in 3 seconds.

Question 8

What is the function of the GAIN knob?

Answer 8

The GIAIN knob can be used to vary the sensitivity of the receiver. This will also result in a variance of color intensity displayed for a radar return.

Question 9

What mode can be used to display areas where all radar energy has been attenuated?

Answer 9

The REACT, or Rain Echo Attenuation Compensation Technique mode changes the background field from black to cyan. Cyan areas should be avoided. Any target detected inside a cyan area should be considered very dangerous.

Question 10

Where does the standby airspeed indicator receive its pitot/static information from?

Answer 10

Pitot/Static 3 provides dynamic pressure to the standby airspeed indicator.

Question 11

What are the different phases of flight of the FMS lateral deviation scale?

Answer 11

There are three phases of flight pertaining to the lateral scale of the FMS:
- Approach(APP): within 2 NM of FAF (non-precision approaches)
- Terminal(TERM): within 30 NM of departure or destination points
- Enroute(no indication): beyond 30 NM of departure and
destination points

Question 12

What does the DR (Amber) annunciation on the FMS CDU mean?

Answer 12

DR (Dead Reckoning) illuminates when a loss of radio updating occurs, as well as other position sensors, for a period longer than 2 minutes.

Question 13

What does the DGRAD (Amber) annunciation on the FMS CDU mean?

Answer 13

DGRAD (Degrade) illuminates when the FMS cannot guarantee the position accuracy for the present phase of flight.

Question 14

How would you perform a Hold at Present Position using the FMZ-2000?

Answer 14

Aircraft must utilizing the FMS for navigation.
Depress the “DIR” function key, selecting “PATTERN”, then “HOLD” on the “PATTERN” page, and finally line-selecting “HOLD” (scratchpad) to the FROM waypoint will set up a standard holding pattern at the aircraft’s present position. Desired changes to the pattern can then be made.

Question 15

What happens to the VPI scale when transitioning to APP mode?

Answer 15

VPI scale changes from 250 feet per dot to 75 feet per dot.
