Pocket-NAV User’s Manual 1.0 Introduction The Pocket-NAV was developed by Cambridge Aero Instruments (CAI) to enhance the GPS-NAV secure flight data recorder, the L-NAV, and the S-NAV glide computers, and the 302 variometer and secure data recorder, by providing a simple graphical user interface. The powerful, low cost, high-resolution graphics capability allows moving map navigation and reduces the number of screens required to present the pilot with necessary information.
2.1 Changes in Pocket-NAV Version 5.0 Beta 2 since Version 4.4 This section lists the changes since version 4.4 for pilots who are upgrading. There is only one version of Pocket-NAV 5.0, Starter, Standard and Plus versions are no longer relevant. There are differences in how the software behaves when connected to different equipment. For example, if you are using a 302 or an L-NAV air data is available to Pocket-NAV and it displays a more accurate vector wind result. Version 5 will run on the Compaq iPaq.
Bug Fixes: Fixed the IGC file to correctly show GTY and GID. SUA base altitude lists are now displayed in meters if meters is selected for SUA altitudes. The last waypoint selection error is corrected. Fixed the “W” attribute bug. An indexing problem affected the US start gate only, the gate used the wrong point. A bug was fixed that showed altitudes and widths incorrectly for some UK airways. The 302, GPS-NAV, L-NAV and Pocket-NAV use unsigned integers for altitudes.
Program Buttons Pocket-PCs have program buttons, four along the bottom and one or two along the left side, that run the builtin programs, “Contacts”, “Calendar” etc. These can be a problem because you usually don’t want to see your calendar during a glider flight. You can set the buttons to activate various programs (including the PocketNAV program) by selecting Start, Settings, and Buttons.
2.1 Hardware Set Up The Pocket-NAV works on the Compaq Palm-PCs and Pocket-PCs including the iPaq. Pocket-PC batteries are not adequate for flying for several hours, and power is provided to the Pocket-PC through your 302 or GPS-NAV using the cable or mounting system provided by Cambridge. The Pocket-NAV software should be purchased from your Cambridge dealer. If you wish, you can acquire the Pocket-PC elsewhere, in which case you will need only the software and cable from Cambridge.
(The Cassiopeia E-10 and E-11 do not provide for easy data transfer to and from a compact flash card, so the cards are not as useful with these units.) Downloading flight logs from the GPS-NAV can eventually fill up the memory on your Pocket-PC. If a compact flash card is present, flights will be stored on the card and will not use Pocket-PC memory. If you are using a Pocket-PC or a newer Palm-PC, an alternative (and easier) method of loading the PocketNAV software is to use a compact flash card.
extremely grateful, as instrument manufacturers and as pilots, to those who have created, contributed to, and maintained this effort. Special use airspace (SUA), roads, rivers, borders and start/finish gates can be entered for display on the map. SUAs include restricted airspace, wave windows, control zones and any other airspace that requires the pilot to understand boundaries. Examples and instructions for entering SUAs are given in Appendix B.
program that is using it, or push the reset button on the back of the Pocket-PC.) If the program has been running with a connection to a GPS you must exit, disconnect the GPS, and re-start the program to use the simulator. (To exit, press the distance box in the upper right, press Quit Pocket-NAV, and press Yes). The message “GPS Wait” will appear if the GPS does not have a valid satellite fix, as when the GPS is initializing.
The Pocket-NAV always loads waypoint and SUA data files that were used the last time the program was run, if the files are available in the ”My Documents” directory, the “My Documents\SUAsandWPs” subdirectory or on a compact flash “Storage Card” in the Pocket-NAV. Files on a compact flash card must be in the “My Documents” subdirectory or the “SUAsandWPs” subdirectory on the card. It then reads the waypoint data, if any, from the GPS-NAV.
Note that, unless you elect to replace the GPS-NAV waypoints, you can always start again by selecting the distance box, Configure and SUA, WP Files from the main screen. (See Sections 3.3.1 Waypoint and SUA Files and 4.8.3 SUA, WP Files.) 3.2 Running the Simulator Starting the Simulator If a GPS is not connected, the program will run the simulator when started as described above.
3.3 Running the Program 3.3.1 Waypoint and SUA Files If a GPS-NAV is connected, waypoints can be transferred to the Pocket-NAV. (Section 3.1 Choosing Waypoint files in the Pocket-NAV, 302 and GPS-NAV explains the options depending on what has been loaded into the GPS-NAV and Pocket-NAV.) If no waypoint files were used on the Pocket-NAV the last time it was run, the waypoint/SUA selection screen shown in Figure 3 will appear.
Figure 4. The Main Flying Screen 3.3.2 The Main Flying Screen Figure 4 show a typical flying screen. The selected waypoint, Luke 2, turnpoint 56, is shown near the top of the screen. The distance to it is at the upper right. The glide altitude required to reach Luke 2, 5,597 feet, as shown at the upper left, and the MacCready setting is in the center. The differential glide altitude, the difference between the altitude required and your current altitude, can alternatively be displayed.
If a task is entered, it is shown with dotted lines. Airspace zones are filled with gray. (Part of the Sky Harbor airspace surrounding Phoenix, Arizona is shown in Figure 4.) Airports are indicated by a horizontal and an angled line suggesting crossed runways. Table 1 shows the waypoint symbols. Attribute symbols for waypoints are set in the waypoint data files. Multiple attribute symbols are combined; for example turnpoint 25 in Figure 4 is a turnpoint and an airport.
Figure 5. Reset Pan appears at the upper right of the map if it has been panned. Note that the plane icon has moved off screen. Figure 6. The arrival radius is shown when approaching a selected waypoint. Arrival Radius and FAI Sector The arrival radius is displayed on the map when headed to the selected waypoint. If the Show FAI Sector box has been checked on the Task Configuration screen, the FAI sector will show at task turnpoints when a task has been entered.
6.) Points logged by the GPS-NAV are marked on the map behind the glider. At small scales the logged points are marked with X’s as in Figure 6. If you see an X within the arrival circle or FAI sector, you have made the turnpoint. The most recent 5000 points are shown on the map. This feature can be shut off by touching the distance box, Configure, More Configure and Tracks On. (See the configure screens below.) Airspace Airspace areas are filled with gray on the map.
selecting the current task turnpoint, the previous task turnpoint, the next task turnpoint in the task list, or the last active waypoint (which may not have been a task point). Figure 8. After touching the active waypoint at the top left of the screen, one of these screens will appear (depending on whether or not you have entered a task) allowing changing to a new active waypoint. Touch the desired waypoint on the map, or select it from those in the boxes. Figure 9.
Turning SUAs off Touching an SUA will show information about it at the top of the screen, and will also make the Off and List buttons appear. (See Figure 9.) These allow you to shut the currently selected airspace off for 12 hours, and to access the list of currently shut off airspaces to view them and to turn them back on. If you inadvertently shut off an airspace, touch another airspace on the map, touch List, touch the airspace name in the list, and touch On. (See Section 4.8.4 12 Hour Off List.
Vector Wind The vector wind (wind speed and direction) is depicted at the lower left. The arrow points in the direction that the wind is traveling with respect to the ground. This is opposite to the direction number set by the pilot; a wind of 5 knots and 180 degrees is from the South, and the arrow will therefore point North. The wind speed and direction can be set by touching the wind icon and the up and down arrows for speed and direction (Figure 11).
GPS-NAV, a screen will appear asking if you wish to send the points to the GPS-NAV. If you answer yes, the points in the task will be transferred to the GPS-NAV, and the task will be declared and verified. If there is not enough space left out of the 250 points in the GPS-NAV, the last points will be overwritten with the task points.
We recommend that you use the Pocket-NAV as your final glide computer and leave the L or S-NAV on one page throughout the flight. The Pocket-NAV does not require as much changing of pages, and pages do not look similar. This reduces the workload and the possibility of confusion. Using both the Pocket-NAV and the L/S-NAV final glide computers can be tempting, but provides little or no useful information and increases eyes in the cockpit time.
4.0 Main Menu Touching the distance button in the upper right corner will show the main menu. Figure 12. Main Menu (Touch distance box at the upper right of the screen.) 4.1 OK The OK button returns you to the main screen. Pushing any OK button in the Pocket-NAV program returns to the main flying screen. 4.2 Edit Task The Pocket-NAV allows you to easily enter and save a task.
Push Edit Task and a task entering and editing screen will appear (Figure 13). The available turnpoints are to the lower right and task turnpoints, when added (Insert or Replc for replace), are to the upper left. Select the turnpoint on the right and where you want to insert, replace or Del (delete) on the left. Done saves the task and returns you to the main screen. The task is shown as dotted lines on the map.
4.3 Show Task Selecting "Show Task" from the main menu shows the task legs, distances, speeds and times. Figure 14 shows the screen for a task that has been started (at 8:58:41). Touching the Estimate Speed box (72 in the figure) allows setting the speed manually to provide an estimate of the remaining time to complete the task and the arrival time (ETA). Figure 14. The Show Task screen. This screen is useful for verifying tasks entered and on pilot option or cat’s cradle tasks. See Section 3.3.
4.6 Select Waypoint This presents a scrollable, alphabetic list of all the waypoints. To search turnpoints only, choose Edit Task. (A task can contain only one turnpoint if desired.) 4.7 Quit Pocket-NAV This exits the Pocket-NAV program. Information in Show Task is erased. You must quit the program and re-start it to change from simulating to running with a GPS-NAV, or vice versa. 4.
4.8.2 Tracks Tracks are the trail of points left behind the glider on the map. Selecting Tracks allows turning the track feature off or on (up to 300 points) and erasing the tracks accumulated so far. 4.8.3 SUA, WP Files Touching SUA, WP Files allows selecting different waypoint and Special Use Airspace data files. This screen also appears when the program is started and no waypoint data is available. See Figure 3 above in Section 3.3.1 Waypoint and SUA Files. This feature is not often used in flight.
Figure 16. SUA Warnings Figure 17. SUA warning message for the Bayreuth Class D airspace.
Figure 18. Setting “Ignore SUAs above” and “SUA warning margin” altitudes. Horizontal Warning Margin Touching SUA Horiz. Margin allows setting the lateral distance from airspace at which the alarm will activate. This should be set large enough (e.g. 500 to 1000 meters) to allow time to consider what the alarm is for and to make a turn. 12 Hour Off List Selecting 12 Hour Off List displays the list of SUAs that are currently shut off for twelve hours.
Figure 19. List of SUAs that are currently shut off. 4.8.5 Task Configuration The Task Configuration screen is shown in Figure 20. Four options can be selected based on pilot preference. Auto Switch TPs causes the turnpoint to switch to the next turnpoint in the task when the glider enters the arrival radius of the current turnpoint. The navigation point and distance change, making it obvious that the current turnpoint has been reached.
Figure 20. Task Configuration Screen 4.8.6 Final Glide Final Glide Info On turns the final glide computer on and off. Total Energy FG includes the current true airspeed, from the L/S-NAV, to be used in the final glide computation. If no L/S-NAV is connected this option has no effect. The total energy height is normalized to the best L/D speed at the current flying weight. If you are flying above the best L/D speed, the additional energy is added to your height.
Figure 21. Final Glide Configure. 4.9 More Configure 4.9.1 Start Gates Two start gates are available. The perpendicular start gate is a line perpendicular to the first task leg. The cylindrical, or US, start gate is a cylinder of limited height around the task start point. Use an SUA data file to create other start gate shapes (see Appendix A). The start gates only appear if a task has been entered.
Figure 22. Select the Start Gate Type. The task can include a variable length start line perpendicular to the first leg. A zero length setting shuts this feature off. Changing the perpendicular gate length (Start Gates) requires using the stylus keyboard, a small keyboard that appears at the bottom of the Pocket-PC screen. The keyboard is variously called the “SIP” or the “Input Panel” on Palm or Pocket-PCs. See Section 2.0 Setting up the Pocket-PC. Figure 23.
Figure 24. US or cylindrical start gate set up. Selecting US Gate On and entering a radius and height will cause the start cylinder to appear around the first point in a task. Be sure that “Ignore SUAs above:” altitude is set to an altitude above the start height. See Section 4.8.4 SUA Warnings above. Set the GPS pressure altitude to the field elevation before takeoff. (Section 4.8.6) 4.9.
Figure 25. Setting the arrival radius. 4.9.3 Polar Data These screens (there are two screens) allow setting the polar data for the sailplane for final glide computations. Set the numbers using the up and down buttons. The first screen shows maximum ballast, empty weight (including pilot, no ballast), and best glide ratio.
Figure 26. Selecting operating units for the Pocket-NAV. 4.9.4 Units Select the desired units on the Units page as in Figure 26. 4.9.5 Preferences This page allows setting various options to show on the map display. Selecting several items will result in a cluttered screen. These are easily experimented with by running the simulator. Other waypoints are all waypoints other than turnpoints, indicated by a “T” in the waypoint files.
Figure 27. Preferences. Selecting More under Preferences allows turning off the two way exchange of data between the Pocket-NAV and the 302 or GPS-NAV and L/S-NAV. Display on the main screen of bearing, track and numeric wind direction can also be turned on or off here. See Figure XX. Active waypoint exchange is not relevant to the 302.
Figure 28. More Preferences 4.9.6 GPS-NAV Data This screen is for the GPS-NAV only, and does not appear if you are using a 302. This screen allows transferring flight logs from the GPS-NAV to the Pocket-PC, transferring pilot information to and from the GPS-NAV, and sending waypoints from the Pocket-PC to the GPS-NAV. Figure 29.
Get Flight Log Files allows selecting and transferring flight logs. The files are put into a “Flights” directory within the “My Documents” directory on the Pocket-PC, and into a “Flights” directory on the compact flash card, if a card is present. The directories will be created if they do not exist already. Flights are saved as both secure “.cai” files and IGC format text files. Pilot Information provides a means of viewing and changing the pilot information in the GPS-NAV. Figure 30.
Appendix A Waypoint files The Pocket-NAV imports waypoint files in the same format as the GPS-NAV files. An example is given below. The last field in each line is an optional comment field. The fourth field contains the elevation, and the fifth contains a designator that can be blank, or any combination of the following: A T L H S F R W airport turnpoint landpoint home start finish restricted waypoint Lines beginning with “**” are comments and are ignored.
Appendix B Airspace, gate, road, river and border data files. The Pocket-NAV reads SUA data files in a format developed by Tim Newport-Peace for airspace in the UK. User files can be created in that format. Airspace for most of continental Europe is provided by Hans Trautenberg and is available from Cambridge Aero Instruments at no charge. The “Europe.sua” file contains this data. (The “Europe.sua” file is in a special, binary format.
