Flight Computers and Data Loggers

Previous system:

SR940 Flightcomputer with analog V/S indicator

 and GP940 GPS/Datalogger

New system has arrived:

Zander/SDI  ZS1 Flightcomputer with analog/digital V/S indicator

and GP941 GPS/Datalogger

Special features:

Remote control integrated in comfortable Stick Grip

High resolution ZS1 display maximized in 80 mm panel opening

Fast analog/digital Vario/SC indicator with needle controlled by a stepper motor

NMEA data and altitude available for use with e.g. Winpilot on an iPaq PDA

The previous SR940 system:

The Flight Computer and the FAI certified GPS/Datalogger form a coupled system.With its large graphics display, the system is state of the art and widely used over the world, especially for competitions but also for recreational x-country soaring. The german, french and dutch national teams are quite focussed on this system.

The current Zander SR940 Flight Computer has proven to be efficiënt and reliable. The graphic display of the computer has a clear black on green/yellow appearance, especially in bright sunlight. A sensitive low current Vario/SC indicator is applied. Total energy compensation is either by TE probe or electronically. Only two cutouts in the instrument panel (80mm and 60mm) are required. GPS function and recording of flight data is realised in a seperate logger described below. The compass option for wind calculation during straight flight and circle wind calculation based on GPS data, provide wind speed and wind direction all the time.

The Zander GP941 GPS/Flight Data Recorder stores the co-ordinates of the flight path, the pressure altitude, time and ENL values of the integrated engine running sensor. Software is available to download the stored data and to convert the data to a so called IGC file for further evaluation of the flight. The units are designed to be used together with the ZANDER SR940 computer, however stand alone operation is no problem, only 12V and the antenna are required. Only one GPS receiver is used for both the flight computer and the GNSS recorder. So “what you see is what you get” meaning that the flight track info presented on the graphics screen of the SR940 is identical to what is stored in the memory bank of the GP940/GP941 recorder. In this way errors or loss of time in visiting waypoints can easily be avoided.

New Zander/SDI system

ZS1                                              ZS1R

Peter Zander has with Franz Pöschl of SDI worked together for quite some time to develop the new generation ZS1 flight computer system, the successor of the well known Zander SR940 and the C4 of SDI. Their coöperation started already with the development of the small GP941 GPS/Datalogger described above, and the new digital Vario/SC indicator shown to the right of the above picture. A fast response stepper motor is applied to drive the needle, therefore this indicator is very responsive to the high quality Vario/SC signal produced by the computer system.

The Zander/SDI ZS1 equipment has officially been introduced at the Aero Friedrichshafen April 2003. Prototype units have been tested in practice. New versions of the firmware can be uploaded to the system any time via a PC connection and WinZan. Many units have found there way now to especially cross country pilots. Development still goes on of course.

For easy and comfortable control of the flight computer, a unique Stick Grip with some switches and buttons is available. When applied, there is no need anymore to reach for the flight computer itself. Almost all pilots using a Zander/SDI system have this remote control stick grip installed in their gliders. A PTT push button is available on the backside of the Stick Grip.
