B2500 Advanced Soaring Flight computer

Situational awareness at a glance plus Voice status and Warning system

*current screen display varies slightly from example above.

The B2500 symbolic display was designed to answer the soaring pilot's questions:

* current screen display varies slightly from example above.

When climbing the display changes and the cruise wind data is replaced by a bar graph display showing average over the whole flight, current thermal average, 20 second average and current Macready setting. Without reading any numbers you can tell if this thermal is worthwhile compared to the whole flight so far, if it is weakening or strengthening and how the Macready setting relates to all this.

This answers the main question while climbing - is this thermal a good one or should I consider leaving?

At the same time the display still shows direction to next turnpoint and wind direction.

Added to a B500 variometer system the B2500 performs all soaring navigation, glide calculations and meteorological information functions and displays them on a simple, clearly presented graphical symbolic display requiring minimum pilot workload for interpretation.

The instrument may also be operated “stand alone” as a soaring optimised GPS unit with suitable GPS data input from a commercial GPS or GPS mouse. There is some small loss of functionality due to lack of air data input.

Previously most flight computers have displayed much data in alphanumeric format and while the data may have been accurate it required too much mental effort to derive meaning and hence to be able to make decisions based on it.

Others have featured highly detailed moving map displays which are eminently suited to IFR navigation in powered aircraft but this isn't the task at hand in a soaring computer.

Almost all have required excessive pilot interaction with switches/buttons/touch screens/menus in a feedback loop with the instrument. Obviously this is not ideal. It results in less time to look OUTSIDE the cockpit.

The B2500 Situational Awareness display de-clutters the displayed information to the essentials for quick decision making and instant understanding.

As much as possible the B2500 is operated "open loop". MacCready, bugs and ballast settings are automatically transferred from the B500 and a pilot quickly learns how many clicks left or right from the main flight display to call up in flight statistics, task planning, moving map or landing site displays. The pilot can look outside while doing this and when he next scans the panel the desired information is there.

Other notable B2500 features

Mark a position, decide to fly to it some time later then return to task navigation all without interacting with the screen.


Wind computer

All the information a soaring pilot needs for better and faster decision making with less workload equals more time to look outside  to look at the magnificent view, clouds, birds, other gliders and air traffic.
