Overview
Flight computer systems are the ultimate stage of functionality.  They include everything you may desire for cross-country soaring flight (see list of features below).  They are designed to help you go faster and farther than you would without a flight computer.  They also reduce your workload by presenting the information you need at a glance so you can enjoy your flight.  Safety is another important factor.  A soaring flight computer can help you decide quickly whether you can make it to your desired destination, or that it is time to make the safe decision and land out.

Improved Safety
Pilots that haven't flown with a soaring flight computer system think that they will decrease safety because the pilot will be staring at the computer rather than keeping their eyes out of the cockpit.  It is my opinion that soaring flight computer systems greatly improve safety because the pilot can glance at the display and know instantly whether he/she is within gliding distance of nearby airports. 

With or Without a PDA
Some of the systems below include a Pocket PC or Palm computer.  I like using PDAs in the cockpit because they offer a lot of power in small package along with a color display and intuitive touchscreen user interface.  It is great to be able to glance down at the moving map on the PDA and see reachable airports highlighted on the screen.  If you want more information you can simply touch the airport you are interested in.  However, the first time you use a PDA in sunlight you will probably be disappointed by the brightness and contrast of the display.  They contrast is not very good in sunlight.  However, many pilots have found that the low contrast is acceptable due to the amazing features available in the soaring flight software that runs on the PDA.  Another nice feature of PDAs is that they are small enough to be mounted closer to the pilot on a gooseneck or articulated arm.  That is nice for pilots that have a tough time reaching the instrument panel. 

Some pilots feel that PDAs do not offer enough contrast for use in sunlight.  Those pilots will prefer soaring systems that feature navigation displays that can be built into the instrument panel (such as the ILEC SN-10 and LX7000.  The user interface is generally not quite as intuitive on those devices, but they are extremely easy to view in sunlight and offer all the functionality found in the PDA soaring flight software accessible through the use of knobs and pushbuttons. 

The decision whether or not to use a PDA in the cockpit comes down to personal preference.  Hopefully future PDAs will offer better sunlight readable displays and panel mounted instruments may eventually feature graphical touchscreen user interfaces.

Building Blocks or Complete Solutions
Some of the systems below are popular because they can be purchased as components and eventually assembled into the complete systems you see below.  For example, the LX1600 and Borgelt B50 are very nice Speed-to-fly variometers that can eventually be upgraded to full featured soaring flight computers systems by adding an IGC approved flight recorder and a PDA running soaring flight software.  Also, the LX160 can be used as a simple speed-to-fly variometer and final glide computer with manual "distance to go" entry and can later be upgraded to accept "distance to go" data from a GPS and can even send flight data to a PDA for use with soaring flight software.  These "modular" or "upgradeable" systems are nice because you can buy the components over time as you can afford them.  However, as popular as these systems are, there is a minor trade-off.  The downside to this modular upgrade approach is that the final system is not as clean as a system that is purchased as an integrated or "all in one" flight computer system.  There are generally more cables and switches necessary and the ultimate reliability is therefore lower because cables fail when you don't want them to.

What Flight Computer Systems Can Do What Flight Computer Systems Can't Do
  • Variometer with audio and averager
  • Speed-to-fly director
  • Wind speed and direction calculated using airspeed and GPS data while circling or cruising
  • Use GPS Position and Pressure Altitude

  • Final Glide Calculations
  • Reachable Airports Highlighted
  • Record IGC Approved flight logs
  • OK for all contests, badges, and records
  • Tasks
  • Flight Statistics
  • Improved safety through quick access to final glide data
  • Not portable
  • Expensive

Please Buy from Me
I work very hard to provide detailed product comparisons for soaring pilots.  I hope you will find this web site useful.  I also offer excellent support to customers who buy from me.  The best way to thank me for the services I offer is to help support my business by buying from me - and telling your friends about my company.

Connecting to PCs that Don't Have RS-232 Serial Connectors
Most flight computers and flight recorders connect to PCs using RS-232 communications.  However, most new PCs do not have RS-232 serial connectors.  These are usually DB-9m (9-pin male) connectors.  There are several ways to work around that issue.  My recommendation is to use an RS-232 serial port PCMCIA Card.  You can see an example here: Socket Serial I/O PC Card   Another solution is to use a USB to serial converter.  However, many of these units to do work as well as one would expect.  David Nadler has compiled a very nice list of devices that have been tested and work well.  You can see his page here: http://www.nadler.com/sn10/SN10_USB_Serial_Notes.html


Example Systems
Below are a few example systems.  I've tried to pull together all the components you need for a complete system.

How to Acquire These Example Systems
Not all the parts listed on this page are available from Cumulus Soaring, Inc.  I don't sell Pocket PCs because they change too rapidly so Pocket PCs and accessories are available through alliances with PC Connection.  In order to purchase all the parts in some of the systems below, you would need to place two orders - one with Cumulus Soaring, Inc., and one with PC Connection.  I can buy them for international customers if you are also buying other parts from me.


Example System with Butterfly Vario Only
The Butterfly vario is a powerful soaring flight instrument with built-in speed-to-fly variometer, simple navigation, final glide calculations, artificial horizon, fully IGC approved logger (not approved yet), FLARM display and other features.  The simple navigation features allow selection of a waypoint from a waypoint database.  Pre-entered tasks are not supported, but you can navigate around a task by navigating from one waypoint to the next - one at at time.  The moving map screen shows waypoints, but not terrain data or airspace.  Final glide to a single waypoint (not around multiple task waypoints) and accurate wind information are displayed.  The large LCD display is used for all data.  The vario display shows not only the current variometer reading, but also the average (green triangle) and the airmass lift/sink rate (blue circle).  This is a complete system for simple navigation.  If the display of terrain data, rivers, lakes, cities, airspace, etc. are desired - you can upgrade the system by adding a PDA or PNA or other navigation display in the future.

Air Data Transfer
Several soaring instrument systems are able to send air data (airspeed, vario, etc.) to a Pocket PC in the data stream with the NMEA GPS data.  Software packages such as WinPilot Pro, pocket*StrePla, SeeYou Mobile and Glide Navigator II can take advantage of the data.   For example, SeeYou Mobile and WinPilot Pro offer climb maximizers and other nice features when connected to an instrument which sends airspeed and vario data.
