What is a critical path?

A critical path defines the operational sequence of a turnaround

Updated today

In AGOA, a critical path is the configured set of turnaround tasks (and optional sub-tasks) to track for a specific airline, airport, and aircraft type, including the target timings that fit within the minimum ground time.

A critical path represents the standard operational sequence you follow during a turnaround and the targets you aim to meet for a successful operation and on-time departure. It is defined for a specific combination of:

  • Airline

  • Airport

  • Aircraft type

For that combination, you set the minimum turnaround time (minimum ground time) and configure which tasks are part of the operation and when each task should occur relative to arrival and departure.

Target timings are typically expressed relative to:

  • Arrival: A + (minutes after arrival) or A - (minutes before arrival, if applicable)

  • Departure: D - (minutes before departure), D + (minutes after departure, if applicable)

Examples of targets:

  • The jetbridge is set at A + 02 (2 minutes after arrival).

  • Passenger disembark lasts from A + 02 to A + 10

  • Bag Search starts at D - 10 (10 minutes before departure)

When defining targets, the critical path must respect operational dependencies and sequence constraints (for example, cleaning cannot start before passenger disembark is finished). Targets should also fit within the minimum turnaround time for the operation.

Within the critical path configuration, you can also enable additional data capture through sub-tasks (for example, recording passenger counts, safety check confirmations, or requesting inspection photos). This information is then available for operational tracking in Station View and for downstream use in Analytics.

To create a critical path from scratch, go to the Backoffice and open the Critical Path section, then select Create a new critical path. If you already have an existing critical path and want to update it, use the icons next to the critical path to:

  • Edit (pencil)

  • Duplicate (copy/paste)

  • Create a specific critical path (+)

  • Delete (X)
