A commercial aircraft may operate through several airports in different countries within a single week. Its flight crew follows established operating procedures, while the aircraft remains subject to defined airworthiness and operational requirements.
On the ground, however, the same aircraft may encounter different handling practices, equipment arrangements and local procedures at each destination.
Some differences are unavoidable. Airport infrastructure, national regulations and aircraft-specific requirements are not identical everywhere.
But unnecessary procedural variation raises an important question: how much inconsistency should aviation accept in an environment where safety depends on coordination?
One Aircraft, Different Ground Environments
Ground handling involves activities ranging from aircraft arrival procedures and baggage loading to cargo handling, equipment positioning and departure preparation.
These tasks may be performed by personnel working for different organisations and serving multiple airlines.
A ground handler supporting several carriers can therefore encounter different instructions for similar activities.
While operator-specific requirements may be necessary, excessive variation can increase training demands and create opportunities for misunderstanding.
The objective should not be to make every airport operate identically, but to establish consistent principles for common safety-critical activities wherever practical.
The Case for Standardisation
The International Air Transport Association (IATA) advocates wider adoption of common ground handling standards.
Its principal references include the IATA Ground Operations Manual (IGOM) and Airport Handling Manual (AHM), which provide industry frameworks for ground operations.
At its Ground Handling Conference in May 2026, IATA reported that more than 40% of organisations submitting an IGOM gap analysis had identified no variations.
However, audit reports in 2025 recorded an average of 32 declared variations, representing approximately 8% of IGOM procedures.
Not all procedural differences represent safety weaknesses.
IATA acknowledged that many declared variations involved wording differences or local requirements exceeding baseline standards.
The priority is to ensure that necessary differences are justified, documented and understood by the personnel responsible for applying them.
Safety Is More Than Compliance
A procedure may exist on paper without being consistently understood or applied.
Effective safety management requires personnel to understand both the actions they must perform and the reasons behind them.
Training, supervision and operational communication are therefore essential.
Standardisation should not become an exercise in producing identical documents. Its practical value lies in reducing ambiguity and improving operational consistency.
Technology Cannot Replace Discipline
Digital systems and modern ground support equipment can improve operational performance.
Equipment incorporating anti-collision technology may help reduce the risk of aircraft ground damage.
Electronic information exchange can also reduce errors associated with manual data entry and delayed communication.
Nevertheless, technology cannot compensate for unclear responsibilities or inadequate training.
Its effectiveness depends on proper implementation, supervision and use.
The Responsibility of Airlines and Airports
Ground handling safety involves several organisations with different responsibilities.
Airlines establish requirements for handling their aircraft, while ground handling service providers deliver services within their agreed scope.
Airport operators influence the working environment through infrastructure, access arrangements and airside safety controls.
Effective coordination between these organisations is essential.
Where procedures differ, the reasons should be clearly communicated. Variations serving no necessary operational or regulatory purpose should be reviewed.
A Question of Industry Culture
Aviation has achieved high levels of safety through disciplined procedures, oversight and continuous improvement.
Ground operations deserve the same attention.
Standardisation does not mean ignoring local conditions or removing necessary operator-specific safeguards. It means establishing a reliable foundation from which legitimate differences can be managed.
The industry should not measure ground handling performance solely by how quickly an aircraft leaves the gate.
A successful departure is one in which the required tasks are completed safely, accurately and with clear accountability.
Consistency is not the opposite of operational flexibility. Properly applied, it helps make safe flexibility possible.
