CNv - XC Features Addendum
On-Line XC User Manual (5-14-2014)
CNVario Manual Addendum – Release 3.5.4089 (7-9-2016) 

This page explains how to use the additional screens that are available in the CNv XC version. The XC version contains all the screens and functions described in the CNv Club User Manual (link above) - plus the following additional Navigation and Tool screens and functions.

CNv XC Encoder Functions
CNV
Red

Top Left (TL) Encoder

  • Fast CW rotation shows Screens Select Menu
  • Fast CCW spin always takes you to Home (Cruise or Climb) Screen
Green

Bottom Right (BR) Encoder

  • Rotation highlights options, waypoints, etc.
  • Push / Click selects displayed option, waypoint or function.

The CNv XC Navigation and Tool screens are very easy to use and can be easily learned in a few minutes using the CNv on the ground before a flight.

The XC version checks for GPS satellites at startup and will display an altitude screen ... or a message indicating a satellite search is in progress.

When at the ALT screen, one TL encoder right click shows OAT screen (if no OAT probe) where OAT may be entered if desired.

A TL right fast twist will bring up the ribbon menu - and 'Navigation' or 'Tools' can be selected to access the XC screens.

The pilot can access six Navigation Screen options:

  1. Recent (the list of recently selected waypoints - newest to oldest)
  2. Active Task
  3. Turnpoints by Number (US) or Spell ID (UK)
  4. Landpoints by Distance
  5. All Waypoints by Type / Name
  6. Task Editor

Note: the CNv will automatically display option 2 (Turnpoints by Number) or 5 (Spell ID) based on the type of turnpoint file loaded. US pilots will typically use Turnpoints by Number ... UK pilots will typically use Spell ID. So a pilot will actually only have four screen options in practice.

The Tools - Waypoint function will display the name of the current loaded waypoint file - and the list of the waypoint files that are available - loaded using the thumb drive. The pilot can keep the current loaded waypoints, or select a different file to load a new set. Only one file can be loaded at a time.

The following presents the Navigation and Tool screens that a pilot will see while using the XC version. The order of the presentation may differ and some screens will not display - depending on the type of waypoint file loaded. In addition, the CNv will display some interim status screens that are not displayed below.

Task Edit
TaskTPs
Cancel

Navigation - Task Editor

The TASK EDITOR is entered by turning the TL encoder one click to the left - from the Navigation ribbon menu. or by scrolling all the way to the right.

The last-entered active task will be displayed ... or a 'No Task' message will be displayed.

The BR encoder is used at his point to perform ALL task edit functions.

New Task Setup

1/ Press the BR encoder to display the list of turnpoints. The bottom highlighted row of the list will be '<<end>>'

2/ Press the BR encoder again to start new task creation.

3/ The initial task screen will display '**NoTask**' to indicate no turnpoints have been selected for this new task setup.

4/ Press the BR encoder to display the turnpoint list.

5/ Scroll down the list with the BR encoder to select a Start point. The first turnpoint selected is always assumed to be the start point and has the prefix 'S:' in the task display.

6/ The task will display the Start at the top of the list and '<<end>>' will be highlighted on the last line.

7/ Press BR encoder to display turnpoints. BR encoder will scroll through the list. Press the BR encoder to add the highlighted turnpoint to the task.

8/ The task will be display with the Start ... and the last selected turnpoint as Finish. The '<<end>>' will be highlighted.

10/ Continue add turnpoints to the bottom of the task using the BR encoder to scroll and select. The last selected turnpoint is always considered the Finish.

11/ When task construction is completed, depress and hold the BR encoder to display the save options.

  • 'Cancel' discards the task. The CNv will revert to the last entered task.
  • 'Declare - No' saves the task ... but does not initialize the declaration.
  • 'Declare - Yes' saves the task ... and does initialize the declaration.

12/ When 'Declare - Yes' or 'Declare - No' is selected, the Start turnpoint becomes the active waypoint.

Active Task Edit

1/ Existing tasks can be edited by changing an existing turnpoint ... or by deleting all turnpoints at a certain point in the task turnpoint list.

2/ Highlight an existing task turnpoint and press the BR encoder to select a replacement from the turnpoint list.

3/ Highlight an existing turnpoint and press the BR encoder to select the turnpoint list. Selecting '<<end>>' at the top of the list will erase that turnpoint and all following. New turnpoints may be selected for the deleted turnpoints to specify the revised task.

 
Tools

Tools - Ribbon Menu

Tools is the last function on the ribbon menu.

Tools - Download Flights (Loading Waypoints)

Insert a USB drive into the ADC USB port.

A list of available log files will be displayed. Select the required log with the BR encoder and push the BR encoder to begin the download to the USB drive.

 
Log

Tools - Log Interval

The flight log record creation rate is adjusted using the BR encoder. The settings will result in creation of log records every 1, 2, 4, 8 or 12 seconds.

 

 
Waypoint

Tools - Waypoint Data (Loading Waypoints)

The Database Information screen allows you to load the CNv with waypoints required for your flight.

1/ Put your waypoint file(s) on a thumb drive and insert into the ADC.

2/ Spin the TL encoder briskly clockwise to bring up the ribbon menu.

3/ Scroll up/down through the ribbon menu with the BR encoder to select Tools.

4/ Scroll clockwise with the TL encoder to the Database Info screen. The CNV will display the name of the current loaded waypoint file - and the number of waypoints. (BGA_2013.STX is displayed in the example on the left.)

5/ Push/click the BR encoder to see the list of waypoint files on the USB thumb drive.

6/ Scroll through the list with the BR encoder and highlight the desired waypoint file. (HOBBS_13.STX is highlighted in the example on the left.)

7/ Push/click the BR encoder to load the waypoints in that file. The CNv will display loading messages and status - then will display a finished message with the file name and the number of waypoints loaded. (HOBBS_13.STX is displayed with 159 waypoints in the example on the left.)

8/ Push/click the BR encoder to bring up the main navigation page. Profile Home is the default.

9/ Select a new navigation waypoint using any of the waypoint selection screens explained in the following sections.

Profile

Tools - Profile

This screen allows profile selection from multiple available to provide different CNv defaults / setups for different pilots or configurations.

The profiles are loaded on a USB drive and are typically selected prior to takeoff.

 
License

Tools - License

This screen allows the pilot to select and install a license from a usb memory stick. Installation is only required once - the CNv will retain the license information.

 
Pilot Event

Tools - Pilot Event

This screen allows the pilot to records pilot event. The time of the last event is displayed.

 

 
OAT

Tools - OAT Manual Adjust

If no temperature probe is fitted the pilot can enter a temperature (or forecast temperature) for the current altitude and the instrument will use that to approximate the temperature with varying altitude.  An estimate within a few degrees will provide good IAS/TAS correction and wind calculations. 

Note: at present we use the standard atmosphere lapse rate.  We may switch to using an adiabatic lapse rate.

OAT probes are available here.
