Key steps of a narrowbody turnaround

The narrowbody turnaround is one of the most repeated operations in commercial aviation, and one of the most densely packed. Deboarding, offloading, cleaning, catering, fuelling, loading, boarding: every task has its own team, equipment and safety constraints, and many run at the same time around the same aircraft. Understanding the steps of a narrowbody turnaround and how they depend on each other is the basis of any punctuality improvement.

This article draws on Airbus’s A320 airport planning documentation, Regulation (EU) 2025/20 on ground handling and IATA’s IGOM. It does not give durations: these depend on aircraft type, stand configuration, load and each airline’s procedures. Airbus itself notes that actual times vary with each operator’s specific practices, resources, equipment and operating conditions.

What is a turnaround?

Regulation (EU) 2025/20 defines the turnaround as a coordinated process of activities associated with the handling of an aircraft, its passengers, baggage, mail and cargo, occurring in a predetermined time interval between the aircraft’s arrival and its departure. EUROCONTROL’s A-CDM manual uses the minimum turn-round time (MTTT): the minimum time agreed with the airline or its ground handler for a given flight or aircraft type.

Two scenarios frame practice. In the turnaround charts of its A320 documentation, Airbus distinguishes a “full servicing” turnaround, at a contact stand with a boarding bridge, with fuelling, catering at the forward and aft doors, toilet servicing and potable water, from a shorter “outstation” turnaround, with two sets of stairs at the forward and aft left doors and no fuelling or water services.

Before arrival: preparing the stand

The turnaround starts before the aircraft is on blocks. Regulation (EU) 2025/20 requires the stand to be inspected before the aircraft arrives, applying the airport operator’s procedures. The equipment restraint area (ERA) around the aircraft must remain free of obstructions and foreign object debris (FOD) before and after arrival and departure and during manoeuvring.

In its A320 documentation, Airbus states that a stand safety line marks out an aircraft safety area of at least 7.5 metres around the aircraft, in which no vehicle may be parked before the aircraft has come to a complete stop with wheel chocks in place. Equipment therefore waits outside that area, ready to move in.

This is also the moment to check that the team and equipment in the turnaround plan are actually assigned and nearby: a loader still busy on another stand when the aircraft arrives means a turnaround that starts late.

On blocks: securing the aircraft

Regulation (EU) 2025/20 sets out what arrival procedures must cover: securing the aircraft on the ground, marking the aircraft danger zones, operating cargo doors and service panels, positioning equipment, including the ground power unit (GPU) and pre-conditioned air unit (PCA) where applicable, and operating the boarding bridge or stairs.

Two rules shape this phase. Only staff with a specific task may approach the aircraft before the anti-collision lights are switched off and the engines shut down. And the equipment restraint area is marked by safety cones around the parts of the aircraft susceptible to ground damage. Chocks secure the aircraft; until they are in place, equipment stays back.

The typical narrowbody sequence

Activities split into parallel streams: the cabin (passengers, cleaning, catering), the holds (baggage, cargo, mail) and the aircraft itself (fuel, water, power). The sequence below follows the activities shown in Airbus’s A320 turnaround charts.

The critical path, in operational terms

The critical path is the chain of dependent tasks that sets the minimum length of the turnaround: any delay on one of them delays departure, whereas a task off the critical path has slack. Airbus marks this critical path on its turnaround charts.

On a narrowbody, the dependency logic is simple to state:

• the cabin: cleaning only after deboarding, boarding only after cleaning and checks, doors closed only after boarding and headcount are complete;
• the holds: loading only after offloading, and closure depends on the last bags and any offloads for no-show passengers;
• fuel: if it cannot be done with passengers on board, it has to fit between deboarding and boarding. Airbus’s full-servicing scenario in fact assumes no fuelling with passengers on board. When fuelling does take place with passengers on board or boarding, Regulation (EU) 2025/20 requires, among other things, that emergency exits and escape routes be kept clear.

The critical path is not fixed. A late inbound, a remote stand, a broken boarding bridge, an unusual number of transfer bags or a passenger with reduced mobility to assist can push a normally secondary task onto the critical path. That is why tracking is done flight by flight, not against an average model.

Safety on stand: IGOM and EU regulation

IATA’s IGOM standardises ground handling procedures. According to IATA, it covers general ramp safety and servicing (fuelling, weather conditions, hand signals), the aircraft turnaround (arrival, doors, departure, towing), load control, and airside safety oversight, including turnaround supervision and incident reporting. Since the 2023 SGHA, the parties commit to applying its procedures.

Regulation (EU) 2025/20, applicable from 27 March 2028, sets detailed operational requirements of its own. For loading: written loading instructions followed, aircraft stability maintained during loading and offloading, ULDs serviceable and matching the instructions, hold doors properly closed, last-minute changes recorded on the mass and balance documentation. For departure: only the staff and equipment needed for start-up and pushback remain in the equipment restraint area, equipment is safely disconnected, the aircraft danger zone is clear, and the final step of engine start is clearly indicated before pushback begins.

The same regulation requires a turnaround coordination function that takes the airline’s turnaround plan into account and makes sure the workload per person does not jeopardise safety.

After departure: handing the stand back

The turnaround does not end when the aircraft pushes back. Regulation (EU) 2025/20 requires the equipment restraint area to remain free of obstructions and debris after departure as well, and the next aircraft may already be on approach. Clearing the stand means returning chocks, cones and equipment to their parking positions, checking for debris left behind and making the stand available again. It is also the right time to record what happened while memories are fresh: which task slipped, which piece of equipment was late, which information arrived too late. Those notes feed the delay coding and, over time, the improvement of the turnaround plan itself. A station that debriefs its difficult turnarounds learns faster than one that only counts them.

Friction points

On the ramp, the same situations come up again and again:

• shared equipment: a loader or tug assigned to two close turnarounds creates an invisible dependency between two flights. Our article on ground support equipment tracking looks at this;
• end of loading: last bags, transfer bags and offloads that delay hold closure;
• last-minute paperwork: every load change must be recorded on the mass and balance documentation before it goes to the captain;
• remote stands: buses, stairs, longer distances, more equipment to coordinate;
• unavailable bridge or infrastructure, which delays deboarding and shifts everything else;
• scattered information: each team knows the status of its own task, rarely that of the others.

How Turnpilot helps

Turnpilot brings passengers, baggage, equipment and aircraft together in a single view per flight. The turnaround control module shows every turnaround at the station in real time, with each flight’s timeline, and the baggage and hold loading module gives the right count before the holds close. On the ramp, the ramp app guides agents one task at a time. The terms used here are defined in the glossary.
