12. Obstacle Warnings

The standard obstacle data base has about 35'000 Alpine obstacles

loaded by ECW100 at manufacture; subsequently the user may upload but not alter up-

dated information by SD card. Special data banks, corrections and amendments can be

reported to us.

The ECW100 display flashes when there is warning of obstacles. The warning always

relates to obstacles straight in-line with the current flight heading. In other words there

is no horizontal or vertical bearing given to the obstacle. The threat level depends upon

the time remaining to impact; the flash frequency increases with reducing distance from

the obstacle. The display is refreshed every second.

A warning is given if an aircraft flies under a cable or power line.

An acoustic warning (beep) is given at the same time as the flashing fixed obstacle warn-

ing. The time between warning and possible collision is brief, just a few seconds. Howev-

er, warnings are given of fixed obstacles earlier than those for other aircraft.

 Moderate threat (less than 28 seconds to calculated collision): Slow flash 2 Hz

 Medium threat (less than 19 seconds): Medium flash 4 Hz

 Immediate threat (less than 10 seconds): Rapid flash 6 Hz
