Overview
Nielsen Kellerman is developing the next generation of soaring instruments.  Their first product is the soon to be released ClearNav flight computer running ClearNavigator soaring flight software by Chip Garner.

Status of the ClearNav
The first "First Flight" units have been shipped to customers.  More First Flight units will ship in early July.  All 10 of my allocation of First Flight units have been sold.  The first production units will be available in mid to late August.  There is likely to be a backlog and long waiting list for the production units.  If you want to get a ClearNav soon I highly recommend that you place and order using the price list below.  Payment will not be due until the unit ships to you.

Great News
I am very excited to announce that I have been contracted to write the manual for the ClearNav.  It will be fun to be a part of this impressive team. 

First Impressions
I am extremely impressed with the hardware and software.  The display has a large and extremely bright screen without the overall dimensions being too large.  I didn't think I was going to like the lack of a touch-screen, but I find the remote to be easy to use and the software very intuitive.  The 3 software features that impress me the most are the way area tasks are supported, the "Glide Amoeba" glide range rings and the way it calculates estimated speed for the remainder of the task.  You can see some of those features in action in the screen captures below.

The Team
The team of people working on the product is very impressive. It includes:

• Richard Kellerman - Soaring Pilot (recent Hilton Cup Winner), businessman
• Dave Ellis - Soaring Pilot, Ran Cambridge Aero Instruments for 14 years, Driving force behind the Cambridge C-NAV, M-NAV, L-NAV, S-NAV, and the first IGC Approved Flight Recorder - the GPS-NAV. He also developed the Cambridge 302 and 303. In my opinion the Cambridge products were industry leaders in regard to ease-of-use.
• Chip Garner - World level soaring competition pilot, Software Engineer, developer of Glide Navigator and Glide Navigator II (originally Cambridge Pocket-NAV) soaring flight software. Big proponent of the "keep the instruments simple - keep your eyes out of the cockpit" instrument design philosophy.
• Phil Schlosser - Worked with Dave Ellis at Cambridge Aero Instruments for 14 years or so. Firmware developer for the Cambridge 302 and many other products.
• Rick Sheppe - Soaring Pilot, functional designer of the Cambridge S-NAV, L-NAV and GPS-NAV.
• Paul Remde - Writing the manual for the ClearNav and creating a cockpit quick reference card

ClearNav Overview
I have sold PDA systems for use in gliders for many years. I'm a fan of graphical moving map displays because they present key information to the glider pilot in a clear way so that one can glance at the display and get a quick overview of how you are doing. You know instantly which airports are within gliding range. That is powerful information and dramatically enhances safety. The problem is that currently available PDAs have small screens that are quite difficult to read in sunlight - they just are not bright enough. NK has designed what I consider to be a fantastic solution. It is a large display that really is easy to read in sunlight.

Key Features

• Large, extremely bright 5.5+" diagonal color LCD screen (the largest PDAs are 4" diagonal).
• The display is not a touchscreen - to maximize screen brightness
• Built-in GPS
• IGC Approved Flight Recorder (Working now, hoping for IGC Approval sometime in 2008)
• Optional pitot and static inputs for measuring airspeed to enhance wind speed and direction calculations. - Even better than the high quality sensors used in the Cambridge 302.
• Remote Keypad - Simple operator interface for operating the screen
• Moving map with selectable layers
• Comprehensive task optimization
• Glide "amoeba" (gliding range footprint) shows areas you can reach, taking wind, glider polar, and terrain into account
• New Method for Area Tasks - A blue arc shows where to turn in the turn area.
• Airmass history
• Airspace Monitor
• Landability status monitor
• Size: 4.25"w x 5.83"h x 1.22"d (108mm x 148mm x 31mm)
• Display Size: 3.39"w x 4.53"h (86mm x 115mm)
• Screen Resolution: 240 x 320 pixels
• Backlight: CCFL (Cold Cathode Fluorescent Lamp) backlight. Nominal luminance is 700 Candelas/m^2 (nits), achieved with a single lamp that goes around 3 sides of the LCD. NK provides lamp overdrive capability up to 1100 nits for severe ambient conditions such as flying into a hazy late afternoon sun. This increases battery drain, so the display is normally operated at its nominal luminance.
• Weight: ~1 lb (450 g)
• Operating System: Windows CE.NET
• Memory: 2 GB of internal memory for turnpoint, terrain, map and airspace information
• Data Transfer: USB Flash Drive and perhaps a built-in SD card reader
• Power Requirements: 9 to 16 VDC
• Power Consumption: 600 mA at full brightness, 300 mA at min. brightness, In power-save mode the backlight goes to full brightness when any key is pressed on the remote keypad. It backs down to min. brightness about 25 seconds after the last key press.
• Compatible with Cambridge 302 - The ClearNav can receive Vector Wind (speed and direction), Real Time Headwind and True Airspeed from the 302. The Vector Wind (speed and direction) and Real Time Headwind can be displayed. The Vector Wind is used for final glide (as the auto wind) if it is available. The True Airspeed is used for the total energy final glide calculation.

Interesting Details
I was very intrigued when I learned that the ClearNav will have a built-in GPS and IGC Approved flight recorder. That eliminates the need to connect it to an external GPS - which makes installation much easier. I imagine it will take several months to a year to get the IGC approval (just a guess).

Area Task Support - Brilliant!
When I first started playing with my ClearNav demo I was extremely impressed with the brilliant new way the ClearNav handles area tasks.  Competitive software requires that you move the turn point within the turn area.  That can be cumbersome and even dangerous to do in flight.  The ClearNav is much simpler and more intuitive.  There is no need to move or manipulate the turn location in any way.  A blue arc is show inside the turn area.  It is a locus of points within the turn area that lie along an ellipse such that making your turn at any point on the line will give you the same distance around the course.  The software places the blue arc automatically based on your estimated speed around the course and the task time.  Task course lines are drawn in fine black lines from the start point, to a point on the blue line and then on to the center of the next turn area.  If you are flying fast then blue arc moves to a point on the far edge of the turn area.  If you are flying slowly the blue arc moves to a point on the near side of the turn area.  When the blue arc reaches the far or near side of the area then the turnpoint in the next turn area moves away from the center of that area to compensate.  For example, if you are flying slowly then the blue arc will move to the near side of the turn area you are headed for and the turn point in the following turn area will move closer to the near edge of that area.  I think this way of handling turn areas is revolutionary and brilliant!  Congratulations Chip Garner on this innovation!  It is brilliant because you never need to move the turn point manually, you just glance at the screen and fly to a point on the blue arc.  That makes flying safer because you will keep your eyes out of the cockpit and it also makes you faster because you can focus your efforts on flying fast - not fiddling with the software.

Glide Amoebas
The glide amoebas show your gliding range graphically on the map.  They take into account the wind, glider polar, altitude and surrounding terrain.  Over flat terrain they look like circular rings.  Over mountainous terrain they look like, well... amoebas. A ridge shows up as a flat "impassable" line while long extended "fingers" show where it is possible to glide through mountain passes or down into valleys. In flat land soaring the footprint will be much more circular or ellipse shaped. This is a very powerful feature.  Past generations of soaring software highlighted reachable airports on the map - which is also nice, but in ClearNavigator you can see at a glance not just what airports are reachable (any airport inside the glide amoeba) but you also know how far you can glide over the ground - or down into a valley.  To me the most powerful feature of any soaring software is the ability to glance at the screen and know instantly whether or not you can make it to a nearby landing site. The Glide Amoebas makes that very clear and intuitive and easy to use in flight - Fantastic!

• The purple arc is the "Glide Amoeba" to a user specified arrival altitude over the terrain You can make it to the purple arc and still have enough altitude for a safe pattern and landing.  The arrival altitude is user adjustable (1000 feet AGL in these examples). The left example is over flat terrain. Note how the rings are shifted to compensate for the wind.  The right example is in mountainous terrain with a ridge in the lower right quadrant of the screen.
• The red arc is the "Glide Amoeba" to ground level.

Calculation of Estimated Speed for the Remainder of the Task - New - Powerful
The ClearNav has a very innovative and powerful algorithm for calculating the estimated speed for the remainder of the task - so that you can finish at the desired time.  The estimated speed is used to estimate how long it will take you to finish the task - and the total time on task.  In contest tasks top pilot do their best to arrive home as close to, but just after the minimum task time.  The reason for that is that the final glide will be a larger percentage of your total task time.  Since final glides are fast (no thermalling), your achieved speed is faster for the entire task when the final glide is as high a percentage as possible of the total task.  Since it is considered important to finish just at or just after the minimum task time, it is important for your soaring software to accurately calculate the estimated time on course.  All brands of soaring software do calculations for the approximate time on course.  In Glide Navigator II the pilot is required to enter his/her best estimate of the speed that will be achieved for the remainder of the task.  That is tough to do accurately because you have to take into account the remaining cross-country speed while thermalling and the speed on final glide.  Great contest pilots like Chip Garner have the experience to do that pretty accurately, but most contest pilots (myself included) have a hard time knowing what number to enter into Glide Navigator II for the estimated speed for the remainder of the task.  Other soaring software (SeeYou Mobile, WinPilot, etc.) have several options available for the calculation of the estimated speed for the remainder of the task.  Most pilots select the option to use the MacCready setting to calculate the estimated speed for the remainder of the task (taking into account thermalling and final glide phases).  They do a pretty good job but they are assuming that you don't find lift while gliding and don't work great when ridge running.  Chip Garner has designed a powerful new algorithm for the ClearNav that is better than all previous methods.  Before the start, it uses the MacCready setting. Once on course the speed is computed based on your climbing and gliding performance so far, predicted out and including the final glide. It includes the wind and a final glide at the current MacCready setting and altitude. If you exceed final glide height it switches to the MacCready glide speed corresponding to that height.  It is not very sensitive to the MacCready setting because it using actual calculated climb and glide data. The glide netto and average climb used in the calculation are shown on both the performance and task dialogs. The prediction works extremely well if conditions do not change appreciably, in which case you can adjust the speed. Chip Garner says he has been able to consistently finish within about 30 seconds of the minimum task time on area tasks using the ClearNav.  This is a very powerful and innovative tool for accurately arriving home at the desired time.

Pitot and Static Inputs
Another very interesting feature is the optional pitot and static inputs for measuring airspeed. However, these will not be available when for a while.  Until they are available I recommend using a Cambridge 302 Variometer/GPS Flight Recorder with the ClearNav because the ClearNav can receive airspeed and wind data from the 302.  When the ClearNav pitot and static input module is available it will allow the ClearNav to calculate wind speed and direction not only when thermalling, but also when cruising. I have been told that the software will not use the inputs to calculate speed-to-fly or variometer functions. It would seem to me that those features would be possible in the long run, but they may be avoiding it in order to keep the operator interface as simple and clean as possible - just speculation. Adding push-pull arrows and a vario needle could make the screen a bit cluttered.


Remote Control
A small remote control is used to control the software.  It includes Arrow Keys (Left, Right, Up, Down), Enter, Zoom In, Zoom Out, Focus (yellow), and Menu buttons.  The operation of the buttons is quite intuitive.  The yellow Focus button changes the focus of the software between the user selectable data shown on the bottom of the screen and a black rectangle in on the moving map.  The rectangle can be used to pan the map to view regions outside the current view, or to select items inside the rectangle.  For example, you can use the Arrow Keys to move the rectangle over airports or airspace on the map. Then press the enter key and you can view airport or airspace data or make an airport in the rectangle the active waypoint so you can fly directly to it.  The Ribbon key is used to display and hide the pop-up menu icons.  They are shown and described below. They appear near the top of the screen.

Ribbon Icons (from left to right)

• Change active waypoint (sorted by distance from current location or by name)
• Bugs (polar degradation)
• Water Ballast
• Map Orientation (North Up or Track Up)
• Screen Brightness
• Task Edit
• Map Settings
• Simulator Settings (speed, turn rate, altitude)
• Settings Menu
• Ribbon Options

Waypoint and Airspace File Compatibility
The ClearNav comes loaded with maps and elevation data for the entire world.  It supports waypoint files in either the Cambridge (Glide Navigator II) ".dat" format or the SeeYou ".cup" format.  It supports airspace files in the Tim Newport-Peace ".sua" format.  Soaring site data is readily available on the internet at the Worldwide Soaring Turnpoint Exchange.  I often use SeeYou or StrePla to import the latest FAA database of public and private airports and then export a subset of local airports to a Cambridge or SeeYou waypoint file.

What Vario to Use with It?
In the long run NK has plans to manufacture a complete line of soaring instruments, but I don't expect any other new products until 2009 at the earliest. Many potential customers have asked me what vario would be the best option for use with the ClearNav. That is tough to say at this point as it is unclear what functions will be supported by the ClearNav in the long run. At the very least most pilots will want a good speed-to-fly variometer. The best option is a Cambridge 302 because the ClearNav can accept airspeed data from the 302 - eliminating the need for the optional Airspeed Sensor option.  Many will probably use a Cambridge 302 because it offers many features in a small box. The IGC Approved flight recorder in the 302 will be redundant in the long run, but who knows how long it will take NK to get IGC Approval for the ClearNav - it could take a year. If so, then a 302 is a great companion product. Once the ClearNav has IGC approval then the 302 would be a great back-up logger. Other units worth considering include the LX1600 and Borgelt B500. If you don't need a speed-to-fly vario then a Tasman V1000, Borgelt B400 or LX16 would work fine.  My guess is that most customers will use Cambridge 302 units with the ClearNav.

Price
The price is $2800.  Details on the included items are included in the price list below. I think it is a great value at that price. There are many glider pilots that are dying to replace their iPAQs with a larger and easier to read (brighter) display.  Keep in mind that this product is much more than a bright and large PDA replacement.  It also has a built-in GPS and IGC Approved Flight Recorder.

My Impressions
As stated above, I am very impressed with the product. I am a big fan of Dave Ellis and Chip Garner's "keep it simple - keep it safe" philosophy and the unit seems to keep to that principle well. I love the Glide Amoebas and the Area Task support.  I like that the screen is not overly cluttered and it is easy to hide the terrain data if you want to see only airports, airspace and "culture" data such as rivers, lakes, cities and roads.  The fonts are large and easy to read.

I must admit that 2 design items surprised me at first. I was surprised that the unit is not a touch-screen because I have long been a fan of the simplicity possible with touch-screens. However, I have been told that this compromise was necessary to ensure maximum screen brightness. Touch-screens consist of plastic layers placed between the LCD screen and the operator and they reduce the amount of light that gets to the pilot's eyes. Another reason to do without the touch-screen is that touch-screens are not ideal for use in a glider cockpit - while bumping along in ridge lift. A handheld or stick mounted keypad is a much better option for use in a glider. I am confident that the keypad solution will be an easy-to-use and intuitive alternative to a touch-screen. A nice side-benefit to the use of a keypad rather than a touch-screen is that there is no need to mount the screen in a location where it is reachable. Often PDAs are mounted on gooseneck or RAM arms to get them closer to the pilot - within reach. That is not necessary with the ClearNav - just mount the keypad within reach.

I was also surprised to learn that the screen resolution is only 1/4 VGA (240 x 320 pixels). Most PDAs use that resolution, so it is not a problem (it is what most soaring pilots are used to), but I have become used to the 480 x 640 resolution on my iPAQ hx4700 Pocket PC. It can be argued that the higher resolution is not an advantage because you don't want to display small text on the screen anyway - you wouldn't be able to read it while bumping along in a glider. I'm sure that is true, but the higher resolution of the hx4700 does make even large text slightly sharper and easier to read. Again, the modest resolution of the ClearNav was necessary to enable maximum screen brightness - which I must agree is a reasonable compromise.

Clearly these 2 complaints are very minor ones. I agree completely that PDAs are not easy to read in sunlight and the ClearNav is much better solution for use in a glider. I am not trying to pick apart the product, but I do feel it is important to mention the compromises up front - so there are no surprises when the customer receives his expensive new soaring toy.

Mounting Options
Several mounting options will be available for the ClearNav. It can be mounted to the front (pilot) side of the instrument panel, or recessed into the panel, or mounted on an optional articulated RAM arm that is attached to the instrument panel.

Second Seat Installation
The same mounting options and components are used when installing the ClearNav in the second seat in a 2 -seat glider. Two ClearNav systems installed in one glider will operate completely independently as they each contain a GPS and full functionality. If one ClearNav is connected to a Cambridge 302 for airspeed data, a CANbus extension cable may be used to connect the two Nexus Boards to enable sharing of the airspeed data. Additional data and function sharing may be available in the future.

Available in the Future

• Optional Airspeed Sensor Module - This module will have pitot and static input to allow the ClearNav to calculate wind while cruising.  Cambridge 302 users will not need this module because the ClearNav can accept airspeed data from the 302 through an RJ connector on the Nexus Wiring Board.  When a 302 or Airspeed Sensor module is not used, the ClearNav will calculate wind speed using wind drift while circling.  The estimated price for this module is $200.

Conclusions
This is going to be an extremely popular flight computer system.

NK-0630	ClearNav In-Panel Mounting Kit Aluminum bezel, standoffs, support bracket and template for mounting ClearNav display recessed into the panel. In the photos at right I used the yellow template as a stand-in for the instrument panel - to clarify which parts are on each side of the panel. Note: The SD card reader slot is mounted on the side of the ClearNav Display and is not accessible from the pilot side of the panel when the ClearNav In-Panel Mounting Kit is used. That should not be a problem because a USB Flash Drive can be used for transferring files through the panel mounted CAN/USB Extension cable.		$65	In Stock
NK-0632	ClearNav RAM Mount Kit In some gliders it is preferable to mount the display on a mounting arm that is attached to the instrument panel.  This is the case when there is not enough room in the panel to mount the unit on the panel.  When mounted on a mounting arm, the unit takes-up less panel real estate.  It is sometimes acceptable to partially block some instruments.  However, I think most customers will find that mounting the ClearNav directly on the instrument panel makes for a cleaner and classier installation than the RAM arm option, but those that prefer the RAM arm option will find that it is a rugged and reliable option. A nice feature of the RAM Mount Kit is that the panel adapter is designed to fit the screw hole pattern for a standard small 57 mm (2 1/4 inch) instrument hole.  That makes it easy to attach through existing holes in a small panel hole, or to a hole reducer in a large 80 mm (3 1/8 in) hole. The kit includes: Short RAM "B" size arm with 1" balls and metal bases.  Same arm as the RAM-B-Arm-Short-MBase found on my RAM page.  If you want a longer arm you can add a RAP-B-201 standard length arm or RAM-B-201-C long arm to use with the included bases.
