2. How it works
ECW100 receives position and movement information from an internal 16 channel GPS
receiver with an external antenna. A pressure sensor further enhances the accuracy of
position measurements. The predicted flight path of a first aircraft — in which ECW100 is
installed — is calculated by ECW100 and the information transmitted by radio, as a low
power digital burst signal at one-second intervals. Provided they are within receiving
range these signals are received by further aircraft also equipped with ECW100. The
incoming signal is compared with the flight path calculated and predicted for the second
aircraft. At the same time, ECW100 compares the predicted flight path with known
obstacle data, including electric power lines, radio masts and cable cars.
If ECW100 determines the risk of dangerous proximity to one or more aircraft or
obstacles, the unit gives the pilot warning of the greatest danger at that moment. The
warning is given by a whistle sound (beep) and bright light emitting diodes (LED). The
display also gives indication of the threat level, plus the horizontal and vertical bearing to
the threat.
The operating range is very dependent upon the antenna installation in the aircraft. The
normal range is about 2 km, but up to 5 km may be achieved in individual cases.
The GPS and collision coordinates of the other aircraft can also be made available for use
in other systems (e.g. external display, speech synthesizer, PDA) via a serial data output.
In addition, ECW100 operates as an IGC compatible flight data recorder if this software
option has been configured.
3. SD card
Use the SD card to update firmware and download flights to your PC.
Firmware update:
To update firmware and obstacle databank put in the SD card before power up ECW100.
The new data updates automatically and shows with the collision LEDs and distance
display. After an update the unit reboots. Check the current firmware version during start
up. The version of the obstacle databank does not display.
Logger files:
Flight recording automatically starts when the aircraft is moving and ends when the unit
is switched off. Switching off or rebooting the device during the flight results in separate
flight record files. Allow at least 2 minutes (if the interval is 4s, our recommended value)
after landing before you switch off the device else you lose the last part of the flight.
Allow more time after landing if the interval is higher. When the memory is full, the
oldest data is overwritten. Always download you flight data before you update the
obstacle databank or the software.
