Alert Descriptions

Remote Alerting (optional purchase)

Alerts for your locations will continue to be generated even if you are not signed in to MxVision AviationSentry Online®, however you will not receive notification via the flashing View Alert button or audible alarm.

Alert Criteria

Select the criteria which when exceeded, will generate an alert in MxVision AviationSentry Online® and cause the View Alerts button to flash red. If selected, an audible alarm will also be sounded on your desktop. All locations created will automatically use the alert criteria setting of your default location, therefore you may wish to set your default alert criteria prior to creating additional locations. Alert criteria and recipient assignments for individual locations can be edited at any time.

If you are under administrator control your Account Administrator will determine your alerting preferences.

Alert Setup

Within the Settings Menu, click the Alerts Menu option and the Alert Criteria submenu option.
Choose a Location and select an Audible Alert. You may wish to set up your default location alerts first. All locations created after your default location alerts have been set will conveniently and automatically use the same alert criteria.
Note: You must have sound capability on your PC to play alarm sounds. If you have selected an audible alarm and the test sound is not heard, you may need to install Active X. Typically a banner appears across the top of your screen with instructions.
Enable the alert types that you wish to receive. For some alert types you will need to enter one or more values. Each location may have its own criteria with the exception of Lightning settings. Some alert types are only available in specified regions of the globe. A complete listing is located in Alert Descriptions.
Select a lead time between one and 12 hours into the future.
If you have purchased the Remote Alerting option you may add recipients to this Location.
Click Save Changes to save the alert settings.

Note:

Avoid excessive alerts that add little additional value come from setting up alerts on too many locations, or setting up too many different types of alerts. Below are the alert rules that should be considered when setting your alert criteria.

Forecast Alerts:

A forecast alert is expired when there are two consecutive hours in which that condition is no longer in the forecast. The expiration allows for a new alert to be sent if the condition is again met. Example: A temporary break of two hours or less in a forecasted precipitation event will NOT cause an alert to be sent a second time. However, after two hours with no precipitation in the forecast the event will be treated as a new event and will generate an alert on the first occurrence. Subsequent occurrences will not generate an alert.
When the forecast condition persists, the alert is not re-issued.

Observed Alerts:

Observed alerts are reset when there are at least two consecutive hours in which that condition is not observed.
When the observed condition persists, the alert is not re-issued.

Manage Alerts

To view the alert status of your locations, click the View Alerts button. The button will flash red, and if selected an audible alarm will sound, when your criteria has been met. The View Alerts button will continue to flash until the alert is archived or deleted. If an alert is not archived or deleted it will be removed after five days.

View Alerts

More details and options for each alert are available by clicking the link within the alert listing.

View details

The alert detail provides additional information.

Alert detail

The detail is displayed along with three options:

	Click Mark as Archived to archive an alert for future reference. An archived alert will remain available for up to two years.
	Click Delete to remove the alert from the list.
	After viewing an alert click Back to go back to the list of alerts.

You can view a list of the archived alerts by selecting View Archived Alerts from the Alert Status menu. You can also choose to view only the new alerts or view all alerts.

Note: When using the Lightning and All Clear alerts you may receive up to six notices within the Alerts screen for each event. The six notices are: advisory, caution, and warning, warning all clear, caution all clear and advisory all clear. They will not always occur in that fashion or order, depending on where lightning is occurring.

Alert Type Descriptions

Alert data will be reported in either English or Metric units as determined by your preference setting, excluding National Weather Service (NWS) based alerts. NWS advisories, watches and warnings will always use English units regardless of the preference setting.

Note: Alerts will retain the unit preferences set at the time they were generated. If an alert is generated and received while using Metric preferences, that alert will remain in Metric units even if the preferences are later changed to English units.

Storm Attributes

NEXRAD radar based alerts are available to US locations including Alaska, Hawaii and Puerto Rico. Storm attribute alerts may be available to some Canadian locations located within 124nm of a US NEXRAD radar site.
