# How to Analyze Fleet Performance

> Interpret fleet utilization charts, compare aircraft hours and revenue, identify underutilized aircraft, and analyze deadhead ratios.

By the end of this guide, you will have interpreted fleet utilization charts, compared per-aircraft performance metrics, and identified opportunities to optimize fleet usage.

<Info>
  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.
</Info>

<Info>
  You need any ops access role to view fleet analytics. Revenue data requires `accounting.read`
  permission.

## Navigate to Fleet Utilization

Open the Operations sidebar, click **Analytics**, then click the **Fleet Utilization** card on the landing page.

**Breadcrumb path:** Ops > Analytics > Fleet Utilization

## KPI strip

Four KPI cards appear at the top:

| KPI                      | What it measures                                      |
| ------------------------ | ----------------------------------------------------- |
| **Total Hours**          | Sum of block hours across all aircraft in the period. |
| **Avg Utilization Rate** | Mean block hours per aircraft per day.                |
| **Total Flights**        | Count of trip legs flown by all aircraft.             |
| **Revenue / Block Hour** | Total revenue divided by total block hours.           |

## Hours by aircraft

The bar chart compares block hours across tail numbers for the selected period. Use this chart to:

* Identify **high-utilization aircraft** that may need accelerated maintenance scheduling.
* Spot **underutilized aircraft** that represent a scheduling or charter marketing opportunity.
* Compare utilization across aircraft types to inform fleet planning decisions.

## Daily utilization trend

The area chart shows total fleet hours by day over the selected period. Patterns to watch for:

| Pattern            | Possible cause                                         |
| ------------------ | ------------------------------------------------------ |
| Weekend dips       | Normal for some operators; charter operators may peak. |
| Multi-day gaps     | Weather events, maintenance grounding, or slow season. |
| Consistent uptrend | Growing demand -- review crew capacity.                |
| Sudden drop        | Aircraft AOG or scheduling disruption.                 |

## Deadhead ratio

The deadhead ratio chart shows per-aircraft non-revenue legs as a proportion of total legs. A high deadhead ratio indicates:

* Frequent positioning flights to pick up passengers at remote locations.
* Opportunities to market empty legs through the charter marketplace.
* Potential route optimization by pairing trips more efficiently.

<Tip>
  Cross-reference the deadhead ratio with the Route Profitability sub-tab to identify city pairs
  where empty-leg marketing could reduce positioning costs.
</Tip>

## Aircraft comparison table

The bottom of the page shows a sortable table with per-aircraft metrics:

| Column        | Description                                |
| ------------- | ------------------------------------------ |
| Registration  | Aircraft tail number.                      |
| Make / Model  | Aircraft make and model.                   |
| Hours         | Total block hours in the period.           |
| Flights       | Total trip leg count.                      |
| Revenue       | Total revenue attributed to this aircraft. |
| Deadhead Legs | Count of non-revenue positioning legs.     |

Click any column header to sort. Click an aircraft row to navigate to the aircraft detail page.

## Use fleet analytics for maintenance planning

In accordance with 14 CFR 5.71, utilization metrics contribute to safety performance monitoring. Aircraft accumulating unusual operating patterns warrant review:

1. **High hours, few flights** -- long-haul routes with high block time per leg. Verify engine cycle counts are within limits.
2. **Low hours, many flights** -- short-hop shuttle operations. Verify landing gear and tire inspection intervals.
3. **Sudden utilization spike** -- check whether maintenance due items are approaching sooner than scheduled.
