Watch mode can be activated either manually or automatically (by speed trigger). In
either case, the watch button must be pressed to disable the watch system - there is no
auto-off.
3.1.2. Emergency Management Framework
The Spidertracks system comes with a two tiered emergency management framework,
which are aligned with the ICAO definitions of
uncertainty
and
alert
. Recipients of these
alert notifications are fully customisable within the Organisational Settings of the website.
3.2. Watch Button
The Watch button has two purposes:
1. To manually activate/deactivate the watch system at any stage of flight when operating
in normal reporting mode; or,
2. To turn the Watch system off when operating under automated watch mode. Note that
the aircraft must be below the configured speed threshold in order to disable the watch
system when operating in automated watch mode.
The watch button will toggle on/off - do not press and hold the button. When disabling the
system the LED indicator will begin to flash once toggled. The Spider has now sent a watch-
off message. Until the message has been sent successfully the Spider’s Watch LED will
continue to flash. It is normal operation for this to take up to 60 seconds. While this is in
process the aircraft must remain in full view of the sky. If the Spider is powered off before
sending the watch-off message, a tier one alert will be raised.
3.3. Mark Button
Up to four pre-programmed macro messages can be delivered by way of toggling the Mark
button the corresponding number of times, i.e. a single toggle will trigger Mark 1 message
to be sent, toggling twice will trigger Mark 2 message to be sent. Each message is geo-
stamped and includes all other parameters of a standard position report.
Configuration of macro messages, recipients and delivery mechanism are configured within
the Organisational Settings of the website.
3.4. SOS Function
A tier-one alert can be initiated immediately by pressing the SOS button. When the SOS
function has been toggled all LEDs across the top of the keypad will flash simultaneously
and the Spider will default to a rapid reporting state (8-10s intervals in the general case).
