## What's here?

The Dashboard provides an overview of all fleet health and operations in the given time period. All graphs show the **current time period**, while the % change indicators compare the current time period to the **previous time period.** (Hint: *All Time* does not have % change)

When reading these graphs, please keep in mind the following definitions:

* A **healthy flight** is one that did not report a Critical [flight status](https://docs.auterion.com/vehicle-operation/fleet-management/flights#flight-status)
* A **compliant flight** is one where the pilot completed the [Pre-Flight Checklist](https://docs.auterion.com/vehicle-operation/auterion-suite-fleet-management/broken-reference)
* An **active vehicle** is one that was *armed* in the selected time period

When exploring the *most common failures*, please be aware that this is an analysis of **the most common reasons a flight was marked as Critical.** This is a reflection of the flight analytics, and should be used to determine common failure cases so that they can be avoided.

## Metrics Explained

### Fleet Health <a href="#fleet-health" id="fleet-health"></a>

Given a time range (default 3 months), fleet health is the percentage of flights that *did not fail*.

%↑ or %↓ is percentage change in the fleet health compared to a prior time window of the same size. The previous window may be smaller than the current window if data does not exist that far back in time.

### Number of Flights/Time/Distance <a href="#number-of-flights" id="number-of-flights"></a>

Cumulative values for a given time range are compared to the first value in the prior time range. These numbers include all flights, both success and failure.

%↑ or %↓ is calculated using the difference between first value in the prior time series and the current cumulative value. This is percent increase or decrease.

### Active Vehicles

Number of vehicles used in a current time range / the number of vehicles that are not archived.

If archived vehicles are flow, the active vehicle percentage may be greater than 100%.
