Normal Tracking vs Watch Mode



There are two modes of tracking that your Spider can be operated in - Normal or Watch mode. As a user of the spidertracks system, it is important that you understand the distinction between these two modes and the implications that arise from each.

Normal Tracking Mode:

When operating your Spider in Normal tracking mode, position reports are sent to the spidertracks system in accordance with the time and distance parameters that have been configured for that Spider. If the Spider stops communicating with the spidertracks system, there will not be any type of notification generated.

Watch Mode:

Watch mode can be activated either manually, by pressing the Watch button on the Spider keypad, or autonomously by configuring the reporting type to Automatic Watch. This can be done within the Aircraft Settings area of the website. When operating your Spider in Watch mode, by default, position reports are sent to the spidertracks system at two minute intervals. This period can be reduced to one minute but cannot exceed two minutes. In the absence of a Watch-OFF message being received, if there is no communication between the Spider and the spidertracks system for a period of 15 minutes, a tier one alert will be raised. 

The following diagram depicts these two tracking modes and the implications of them in a decision tree format. To learn more about what you should do if you receive an SOS notification see SOS Alert Notification.

    If you are subscribed to a Flex-plan and are set-up to have 10 minute reporting cycle, by activating a watch, is the unit now forced into a 2 minute reporting cycle?

    Hi there, yes this is the case. You can activate the Watch feature during flight, and a number of people do this. They will fly in good conditions through easy terrain on a larger reporting interval, then press watch if they encounter problems, weather, or are flying over water. I hope that this helps.

    Is there any chance of offering a 5 minute watch feature? We fly helicopters. Two minutes in a helicopter is a much shorter distance than two minutes in a fixed-wing aircraft. The 5 minute option would be more cost efficient solution.

    Hi, at this time we only have the one or two minute option for the Watch system. Thank you. Luke.
