Alert management

1       Introduction 

Alert management 

In this topic, Administrators learn how to update and activate or deactivate alerting rules for the aircraft in your fleet. You learn how to use the two levels of alert and how to modify each of the alert rules. 

We estimate that this will take 3 minutes to complete.

2       Detailed explanation 

Alerting rules apply to the aircraft in your fleet only.

You can configure and modify alerts based on the following criteria:

        Signal lost

        New destination

        Minimal flight level during cruise

        Squawk

        Vertical speed

        Horizontal or vertical deviation from flight plan

        ETA

 

Alert criteria

N-Tracking supports several different types of alerts:

 

        Signal Lost: Loss of ADS-B, ACARS or any other data source position for this individual aircraft
You can configure the threshold time in minutes.
 

        New Destination: New destination airport activated on FMS
 

        Minimal flight level during cruise: Aircraft goes below FL150, 20 minutes after take-off or 30 minutes before landing
You can configure the threshold flight level.
 

        Squawk: Emergency/distress code on transponder
You select the transponder code that raises the alert.
 

        Vertical Speed: Vertical speed during descent 
You can configure the threshold vertical speed in feet per minute.
 

        Horizontal and vertical deviation: The aircraft deviates from the flight plan.
 

        ETA: ETA is later than ETA set at takeoff.
You can configure the threshold time in minutes.

 

Alert thresholds 

Each alert rule has two levels of severity:

        a caution -- triggered when the lower value of a threshold is breached

        a warning level -- triggered when a higher and more significant threshold is breached.

 

Accordingly, more attention should be given to warnings compared to cautions.  

Default alerting rules 

By default, N-Tracking uses the following alerting rule settings:

Signal Lost:

        Warning -- Loss of flight radar feed and/or ACARS information after 11 minutes

11 minutes corresponds to the sum of:

  1. One minute: After 1 minute without flight radar information, N-Tracking asks for an ACARS position message.
  2. Ten minutes: After a delay of 10 minutes between two ACARS position reports, N-Tracking emits a warning. 


New destination:

        Caution -- New destination airport activated on FMS because of a diversion etc.
 


Minimal flight level during cruise:

        Caution -- When the aircraft is flying below FL150, 20 minutes after take-off or 30 minutes before landing.

 

Squawk:

        Warning -- Emergency/distress code on transponder

Vertical Speed:

        Warning -- vertical speed exceeded - 7000fpm

        Caution -- vertical speed exceeded - 5000fpm

ETA:

        Caution -- Last received ETA is more than 15 minutes from ETA received in OFF message

        Warning -- Last received ETA is more than 20 minutes from ETA received in OFF message

To change the rule, click the Edit icon for the corresponding rule.

Interaction 1

Interaction 1 Click the Edit icon.

Interaction 1

Interaction 1 Click the Threshold input field.

You can use the Activated slider on the ALERT RULE MODIFICATION panel to activate an alert OR you can activate it on the list on the Alert Management page. 

When you activate an alert, N-Tracking immediately emits alerts for any flights for which the threshold conditions are met.   

Interaction 2Interaction 1

Use the information in brackets as guidance for the value you enter.

In this example, the number of minutes should be between 1 and 15. 

Interaction 1 Enter 10 into the Threshold field.

You cannot edit any of the fields that are grayed out.

In this example, you enter the threshold value and save the change.

Your next step is to activate the alert, which triggers N-Tracking to monitor if a threshold is breached.

Interaction 2 Click the Save rule button.

If you choose to use the Mail option and/or create a mail distribution list (by clicking Add Contact), mail addresses are checked to make sure they follow the standard format for an email address e.g., name@domain.extension.  

Use the Activated slider to activate the alert.

You can activate alerts from this list of alerts or from the ALERT RULE MODIFICATION panel. 

Interaction 1

Interaction 1 Click the Activated slider.

When you activate an alert, N-Tracking immediately emits alerts for any flights for which the threshold conditions are met.  

Interaction 1

Next, review what activating this alert means for the map display.

Interaction 1 Click the Map tab.

The three flights whose aircraft labels display in red meet the Warning threshold.

The Flight List shows there is also one flight that meets a Caution threshold. 

Interaction 1

Click the plane icon for SCX293 to view the warning text. 

Interaction 1 Click the plane icon.

Review the warning detail.

This warning has already been acknowledged by user "Jinal". 

Interaction 1 Click anywhere on the map.

By default, N-Tracking uses red and orange, respectively to color the aircraft labels and the Flight List section headers for aircraft to which warnings and cautions apply. However, you can customize these color choices, using the Color menu item on the Administration menu.

For more detailed information on using the Color menu item, consult the topic, Customizing colors used on N-Tracking maps.
 

Interaction 2Interaction 1

Interaction 1 Click the User name (Admin_PF) dropdown button.

Interaction 2 Click the Administration menu item.

Interaction 1

Interaction 1 Click the Color menu item.

To change these default color settings for warnings and cautions, consult the topic "Customizing colors used on N-Tracking maps." 

Interaction 1

Interaction 1 Click the Map tab.

You now know how to set up rules that cause alerts to be triggered within N-Tracking. You've also learned how to access their details through the Flight Details pane for an aircraft subject to a warning or caution alert.

The topic "View automatic alerts and create manual alerts" in User Settings provides more information on working with alerts -- and notifications of alerts. Be sure to review that topic to complete your understanding of alert functionality.
