The Operations module must be enabled for your workspace. You also need the appropriate operations permissions. Contact your workspace administrator if you cannot access these features.
Predictive maintenance features require the Ops module and the DOM (Director of Maintenance) or Maintenance role. Pilots with read-only access can view alerts for their assigned aircraft but cannot acknowledge or configure thresholds. Contact your workspace administrator if you cannot access Ops > Predictive Maintenance.
By the end of this guide, you will have viewed the predictive maintenance dashboard, reviewed AI-generated alerts for aircraft components, acknowledged or dismissed alerts, explored trend analysis for engine parameters, set up custom thresholds, and exported trend data for external analysis. For reference information on alert severity levels, monitored parameters, and threshold configuration options, see Predictive Maintenance Reference.

​
View the predictive maintenance dashboard

1
Step 1: Open Predictive Maintenance
2
Navigate to Ops > Predictive Maintenance. The dashboard opens with a fleet summary showing each aircraft in your fleet and its current alert status.
3
The fleet summary tiles show:
4
FieldDescriptionTail numberAircraft registration identifier.Alert countNumber of active alerts grouped by severity.Trend statusWhether any monitored parameter is showing a degrading trend.Last data pointTimestamp of the most recent parameter reading imported for this aircraft.
5
Step 2: Filter the fleet view
6
Use the filter bar to narrow the view:
7
  • By alert severity: show only aircraft with Warning or Critical alerts.
  • By parameter: show only aircraft with alerts on a specific parameter (e.g., EGT, oil pressure).
  • By aircraft type: useful for multi-type fleets.

    Review AI-generated alerts for aircraft components

    1
    Step 1: Open an aircraft’s alert list
    2
    Click an aircraft tile to open its detail view. The Alerts tab lists all active alerts for this aircraft, sorted by severity (Critical first).
    3
    Each alert shows:
    4
    FieldDescriptionParameterWhich engine or airframe parameter triggered the alert.Engine/positionLeft engine, right engine, APU, or airframe location.SeverityInfo, Watch, Caution, Warning, or Critical.DetectedWhen the system first identified the anomaly.TrendDirection and rate of parameter change (rising, stable, falling).Recommended actionAI-generated suggested action (inspect, borescope, schedule check).
    5
    Step 2: Review the alert detail
    6
    Click an alert to open its detail view. The detail view includes:
    7
  • Parameter chart: a time-series chart of the parameter over the alert detection period, with the alert threshold overlaid.
  • AI analysis summary: a plain-language explanation of why the alert was generated, what pattern the model detected, and what the recommended next step is.
  • Historical context: how this reading compares to the aircraft’s own baseline and to fleet averages for the same aircraft type.
  • Related alerts: other parameters that are trending in related directions (useful for diagnosing compound issues).
    • 8
    AI-generated alerts are advisory. They must be evaluated by a qualified aviation maintenance technician (AMT) before any maintenance action is taken. PlaneConnection does not make airworthiness determinations.

    ​
    Acknowledge or dismiss alerts

    1
    Step 1: Open the alert detail
    2
    Navigate to the alert you want to act on as described above.
    3
    Step 2: Choose an action
    4
    Three actions are available on each alert:
    5
    ActionWhen to useAcknowledgeYou have reviewed the alert and are taking action. Links to a work order or note.DismissThe alert is not actionable (e.g., a known sensor anomaly, data entry error).EscalateThe alert requires immediate attention beyond the current maintenance schedule.
    6
    Step 3: Acknowledge an alert
    7
    Click Acknowledge. You will be prompted to:
    8
  • Enter a note describing the review or action taken.
  • Optionally link the acknowledgment to an existing work order, or create a new work order directly from the alert.
  • Set a follow-up date if further monitoring is required.
    • 9
    Click Save Acknowledgment. The alert moves from the Active list to the Acknowledged list and is visible in the audit trail.
    10
    Step 4: Dismiss an alert
    11
    Click Dismiss. Enter a reason for the dismissal (required). The alert is removed from the active view but remains in the alert history for future reference.
    12
    Dismissed alerts will re-trigger if the parameter continues to exceed the threshold. Dismissal applies only to the current alert instance, not to the threshold rule itself.

    ​
    View trend analysis for engine parameters

    2
    From an aircraft’s detail view, click the Trends tab. The trends view shows time-series charts for all monitored parameters.
    3
    Step 2: Select a parameter and time range
    4
    Use the parameter selector to choose a specific parameter (e.g., EGT, N1, oil pressure). Use the time range picker to select the analysis period:
    5
  • Last 30 flights: useful for detecting short-term degradation.
  • Last 90 days: standard trend analysis window.
  • Custom range: for specific event investigations.
    • 6
    Step 3: Interpret the trend chart
    7
    Each trend chart includes:
    8
  • Data points: individual readings from each flight.
  • Trend line: a smoothed regression line showing the overall direction.
  • Baseline band: the expected range for this aircraft and parameter based on its history.
  • Alert thresholds: horizontal lines showing Watch, Caution, Warning, and Critical threshold levels.
  • Annotations: maintenance actions, threshold changes, and alert events overlaid on the timeline.
    • 9
    Use the Compare option to overlay trend lines for left and right engines side by side. A diverging gap between engines is often an early indicator of an asymmetric condition worth investigating.
    10
    Step 4: View statistical summary
    11
    Below each trend chart, a statistical summary shows the mean, standard deviation, minimum, and maximum values for the selected period, alongside the trend slope (units per flight hour) and an AI-generated assessment of whether the trend is within normal bounds.

    ​
    Set up custom thresholds

    1
    Step 1: Open threshold configuration
    2
    From the aircraft’s detail view, click Configure Thresholds. The threshold configuration screen lists all monitored parameters for this aircraft with their current threshold values.
    3
    Step 2: Select a parameter to configure
    4
    Click a parameter row to expand its threshold settings.
    5
    Step 3: Set threshold values
    6
    For each threshold level (Watch, Caution, Warning, Critical), enter the value at which the system should generate an alert. Values must follow the correct order (Watch ≤ Caution ≤ Warning ≤ Critical for rising parameters, reversed for falling parameters).
    7
    You can also configure:
    8
    SettingDescriptionAlert directionRising, falling, or either direction from baseline.Consecutive exceedancesNumber of readings above threshold before alerting (reduces noise).Baseline sourceAircraft-specific baseline, fleet average, or manufacturer limits.Notification channelsWhich alert severity levels trigger SMS or email notifications.
    9
    Step 4: Save the configuration
    10
    Click Save Thresholds. Changes apply to future data points immediately. Historical alerts are not retroactively affected by threshold changes.
    11
    Setting thresholds significantly above manufacturer limits may cause the system to miss genuine alerts. Always verify custom thresholds against the aircraft’s approved flight manual (AFM) and applicable maintenance manuals before saving.

    ​
    Export trend data

    2
    Navigate to the aircraft’s Trends tab and select the parameters and time range you want to export.
    3
    Step 2: Click Export
    4
    Click Export Trend Data. Choose your export format:
    5
    FormatContentsUse caseCSVRaw parameter readings with timestamps and flight IDs.External analysis, maintenance software import.PDFFormatted trend charts with statistical summaries.Management review, regulatory submissions.
    6
    Step 3: Download the export
    7
    Click Download. The export file is generated and downloaded to your device.
