Avionics - Navigation & Communications

Question 1

What pilot actions are required to initialize the FMS?

Answer 1

It is not necessary to initialize manually. The FMS self-initializes when a valid GNSS signal is
received.
If manual initialization is necessary, press the LOAD softkey to the right of the desired
navigation sensor or LAT/LONG indication.

Note: This practice is highly discouraged due to the errors induced in the system if the aircraft is not in the specific location.

Question 2

What information is displayed on the FMS INIT page?

Answer 2

Time and date (synchronized with GPS)
Navigation database status
Databases and part numbers
Sensor status/position

Question 3

How does the crew inhibit the terrain awareness alerting when landing at an airport not in the navigation database?

Answer 3

Select the TAWS TERRAIN PBA to OFF

Note: there is no written procedure for landing outside the FMS data base.

Question 4

How does the pilot change radio frequency spacing (8.33 or 25kHz)?

Answer 4

Via the CTP or CNS on the VHF Control Mode page

Question 5

How is DME hold activated?

Answer 5

Via the CTP NAV Control Mode page or via the CNS checkbox

Question 6

When GNSS data is not available, what does the FMS revert to for position computations? FMS Ops Guide

Answer 6

The FMS reverts to DME/DME
If 2 suitable DME stations are not in range, the FMS reverts to VOR information (radial & DME)
If no ground-based navigation aid is available, the system will revert to IRS.
Switching between modes is automated

Note: If operating in DME/DME, selecting “AUTO TUNING” will cause the system to operate
in DME/DME/DME which is more accurate.

Question 7

From the audio panel, how does the pilot enable the hot mic?

Answer 7

VOX button is unlatched (raised position)

Question 8

What does turning the VOX button on the audio control panel do?

Answer 8

Adjusts the microphone sensitivity

Question 9

What does turning the ST button on the audio control panel do?

Answer 9

Adjusts the sidetone audible feedback level for transmissions

Question 10

What is the meaning of a black FMS MSG soft key at the bottom of a MAP or FMS format?

Answer 10

Message(s) have been read

Note: A gray MSG means no FMS messages; an amber or white MSG indicates the color of
the most urgent unread message

Question 11

What color will manually entered V-speeds be on the airspeed tape?

Answer 11

Cyan

Question 12

Where are manual adjustments to Vref made?

Answer 12

On the VNAV-THRST page ARR tab

Note: the dialog box is limited to corrections of +10kt or less

Question 13

What does changing the RWY ID on the ARR PERF page 1 accomplish?

Answer 13

Changes the runway used for calculating landing distances and crosswinds
It only changes the runway for the performance data and doesn’t change any navigation functions

Note: Typically used for circle-to-land

Question 14

What page in the FMS can climb gradient calculations be made?

Answer 14

DEP PERF page 2

Question 15

When will takeoff V-speeds post to the airspeed tape?

Answer 15

When the actual airplane configuration matches the settings selected for takeoff and
An altitude is set in the ASEL and
The data is sent
