If you have run a construction job or an IT roll-out, you already know how to find the critical path. In aviation the method is the same; what changes is which activities end up on it: a night-time runway window, an approval from the authority, a certification test or a part that does not arrive. If you are an engineer or a PM (project manager) from construction, IT or industry, this article shows what an aviation project manager does, how the job differs from yours and how the critical path behaves in five real types of project. And, at the end, why in aviation the critical activity is not always the longest one.
In 30 seconds
- An aviation project manager leads projects at airports, manufacturers, airlines or maintenance organisations, with aviation safety and the regulator inside the scope.
- The method is the same as for any PM; the context changes: round-the-clock operations, certification, traceability and many stakeholders.
- The critical path is often set by operational windows, approvals, certification, supply and the operational transition.
- The PMP (from PMI) and PRINCE2 (from PeopleCert) are valued, but they do not replace knowledge of the sector.

What an aviation project manager is and what the role involves
An aviation project manager is the person responsible for delivering a project in the sector —works at an airport, a manufacturing programme, a new system or a maintenance check— on time, on budget and within scope, while complying with aviation safety rules and the requirements of the authority.
In this article, “safety” means that operations do not cause accidents. It is not “security”, which is protection against unlawful acts.
Responsibilities of an aviation project manager
The same as any PM, each with an aviation twist:
- Scope and requirements, including regulatory requirements.
- Planning and the critical path, with operational windows and authority milestones as constraints.
- Budget and change control: in a certified environment, a change may require a new assessment.
- Project risks and safety risks.
- Stakeholder coordination, from airlines to contractors.
- Quality, configuration and documentation, so that every decision is traceable.
- Communication and reporting.
Job postings in the sector repeat these responsibilities and almost always ask for experience managing technical projects.
Where the role sits: airports, manufacturers, airlines and MRO
- Airport operators and concessionaires: works, systems, terminals and master plans.
- Manufacturers: aircraft and component programmes, with certification running in parallel.
- Airlines: fleet, systems, cabins and digital transformation.
- MRO (maintenance, repair and overhaul): heavy checks and modifications.
Add engineering firms and consultancies. The role can be filled by an engineer or by a manager, as we explain in aeronautical engineer vs airport manager. So what really changes?
How an aviation project manager differs from a construction or IT project manager
The method is the same; what changes is who can stop the project, when you can work and how much you must document.
| Construction PM | IT PM | Aviation PM | |
|---|---|---|---|
| Who can stop the project | Permits, inspection, client | Client, information security | Also the aviation authority and operations themselves (safety) |
| When work happens | Site hours | Deployment windows | Operational windows (nights, runway closures, low season) at an airport that never closes |
| What gets documented | Design and completion certificates | Requirements, code, tests | All of the above, plus traceability and configuration required by regulation (certification, maintenance) |
| Risks managed | Schedule, cost, occupational safety | Schedule, cost, cybersecurity | Also risk to aviation safety, with a formal assessment before anything changes |
| Stakeholders | Developer, contractor, public administration | Users, business, suppliers | Operator, airlines, ground handlers, air navigation services, police and security forces, authority, neighbouring communities |
The regulator is a stakeholder that can stop the project
In Europe, common rules are set by EASA (European Union Aviation Safety Agency) and enforced by each national authority, such as AESA in Spain. Elsewhere, the national civil aviation authority is the reference: the GCAA in the United Arab Emirates, GACA in Saudi Arabia or the FAA in the United States, and AFAC, Aerocivil or ANAC in Latin America. Their approvals and inspections are fixed milestones in your schedule.
The airport never closes: you work while operations continue
Regulation (EU) No 139/2014, in point ADR.OPS.B.070, requires the aerodrome operator to have procedures ensuring that works do not compromise aircraft safety and that operations do not compromise the safety of the works. In practice: phasing, night windows, NOTAMs (notices to airmen) and daily coordination with operations.
Safety, configuration and traceability
Before changing anything that affects operations, its risk is assessed within the SMS (safety management system), the framework set out in ICAO Annex 19 (International Civil Aviation Organization). We run a course on safety management and SMS implementation for readers who want to go deeper.
Configuration management and documentary traceability come on top. If you come from IT: for airborne software, the reference is DO-178C, and its evidence requirements shape the pace of iterations. With that clear, on to the tool whose meaning changes the most: the critical path.
What the critical path is and why other activities drive it in aviation
You already know the method; what matters is which activities occupy it in aviation.
The critical path (CPM) in one definition
The critical path is the longest sequence of dependent activities in a project. It sets the shortest possible duration: any delay to one of its activities delays the end date. Activities outside the critical path have float, a margin they can use up without moving the finish.
CPM (critical path method) was born in the late 1950s at DuPont, with Remington Rand, and PERT (Program Evaluation and Review Technique) in the US Navy for the Polaris programme, according to ENR.
CPM and PERT: how they differ
CPM uses one duration per activity; PERT uses three estimates to handle uncertainty.
| CPM | PERT | |
|---|---|---|
| Duration of each activity | One estimate | Three: optimistic, most likely and pessimistic |
| When it fits | Known durations (repetitive works) | High uncertainty (development and certification) |
| Aviation example | Pavement rehabilitation | Test campaign for a new system |
In aviation, the two coexist.
What usually drives the critical path in an aviation project
This is the core idea: five drivers that come up again and again.
- Operational windows: on the runway or apron you can only work at certain times or seasons.
- Approvals and certification: authority, tests and inspections. Money cannot compress them.
- Long-lead supply: visual aids, baggage systems or aircraft parts, sometimes critical from day one.
- Third-party interfaces: access roads, power, air navigation services and airlines.
- Operational transition: trials, staff training and transfer day.
Compressing it through crashing (more resources) or fast-tracking (overlapping activities) has a limit: you cannot overlap what safety requires to be done in sequence.
Teaching example: rehabilitating a taxiway at an operating airport
Teaching example: the activities and durations are invented and do not correspond to any airport.
| Activity | Duration (weeks) | Depends on |
|---|---|---|
| A. Safety risk assessment and coordination with operations | 3 | — |
| B. Phasing plan, notification to the authority where required and NOTAM publication | 2 | A |
| C. Manufacture and delivery of the airfield lighting | 6 | — |
| D. Works, phase 1 (night windows) | 4 | B |
| E. Works, phase 2 | 3 | C and D |
| F. Inspection, lighting tests and reopening | 1 | E |
Path A-B-D-E-F adds up to 13 weeks and is the critical one. Path C-E-F adds up to 10, so the lighting supply has 3 weeks of float. If it slips by more than 3 weeks, it becomes critical.
The lesson? In aviation, the critical path starts with safety (A), not with the works. Now for real projects.
The critical path in five types of aviation project
The same structure for all five: what it is, what drives its critical path and an example, a real one where a source supports it.
1. Works at an operating airport
Pavements, airfield lighting or terminal refurbishments with passengers inside. What is critical: operational windows, ADR.OPS.B.070 procedures, NOTAMs and coordination with operations.
One example is the Madrid-Barajas expansion that Aena, the Spanish airport operator, awarded to Luis Vidal Architects: a new passenger building connected to terminals 1, 2 and 3, which will be refurbished, and an expansion of T4.
2. Master plans and major expansions
The airport master plan sets an airport’s long-term development: capacity, land use and phasing. The international reference is ICAO Doc 9184, Part 1; in the United States, the FAA publishes Advisory Circular 150/5070-6B on airport master plans. In Spain, Aena’s regulated investment is planned in five-year periods in the DORA (Airport Regulation Document), according to Aena.
Here the critical path usually runs through the approval process (environmental assessment, permits, consultations) rather than through construction. For the Spanish case, see our summary of airport planning at Aena.
3. Opening a terminal: ORAT and transfer day
ORAT (operational readiness and airport transfer) is the discipline that prepares people, processes and systems to operate a new facility. Transfer day closes its critical path. Three cases:
- Heathrow T5 (2008). It opened on 27 March 2008 with failures in baggage, car parking and security searches. The House of Commons Transport Committee blamed them mostly on insufficient communication between BAA, the operator, and British Airways, and on inadequate training, according to The Register and the committee’s report. British Airways admitted it should not have absorbed construction delays by cutting testing time.
- Berlin Brandenburg (BER). It opened on 31 October 2020, nine years late. In 2012 works had to stop because the fire safety devices did not work and the inauguration was cancelled, according to an AFP report (in Spanish).
- Lima-Jorge Chávez (2025). The new terminal began a trial operation on 15 May 2025 to test systems and services, according to El Peruano (in Spanish). Full transfer came on 1 June, with twelve hours without flights at either terminal, according to Infobae (in Spanish).
4. Aircraft programmes and type certification
In an aircraft or component programme, certification —governed in Europe by Part 21 (Regulation (EU) No 748/2012) and in the United States by the FAA— is a project within the project: certification basis, demonstration of compliance and testing.
The critical path usually runs through those tests and the authority’s acceptance, where uncertainty calls for PERT estimates. For context, see our guide to the aeronautical industry.
5. Heavy maintenance checks at an MRO
The target is TAT (turnaround time, the time the aircraft is out of service), with Part 145 (Regulation (EU) No 1321/2014) as the European framework.
The critical path is planned around routine tasks, but non-routine findings —corrosion found when a panel is opened— and parts change it: another airline’s AOG (aircraft on ground) can compete for the same spare. More in our article on aeronautical maintenance. For all this, the sector has its own tools.
Management tools specific to the aviation sector
On top of the tools any PM uses, the aviation project manager works with frameworks of the sector’s own.
| Tool | What the PM uses it for | Published by |
|---|---|---|
| Doc 9184, Airport Planning Manual (Part 1, master planning) | Structuring an airport master plan | ICAO |
| ADRM, Airport Development Reference Manual | Sizing terminals and setting levels of service | IATA, in collaboration with ACI |
| SMS and management of change (MOC) | Assessing the safety risk before changing anything | ICAO Annex 19; in the EU, EASA regulations |
| EN 9100 / AS9100 | Quality management system for the aerospace industry, with configuration and risk management | IAQG (EN 9100 in Europe, AS9100 in the Americas) |
| DO-178C | Development and certification of airborne software | RTCA (in Europe, EUROCAE ED-12C) |
| TRL scale (1–9) | Measuring the maturity of a technology before deciding to implement it | Originated at NASA; ISO 16290 standard |
| Gantt, CPM/PERT, earned value and scheduling software (for example, MS Project or Primavera P6) | Scheduling, calculating the critical path and controlling time and cost | Market tools |
For planning airports: ICAO Doc 9184 and IATA’s ADRM
ICAO Doc 9184, Part 1, is the international reference for structuring a master plan. The ADRM, produced by IATA (International Air Transport Association) in collaboration with ACI (Airports Council International), helps size terminals against levels of service.
For managing risk: SMS and management of change
Management of change, or MOC, requires the safety risk to be assessed before modifying a facility, a procedure or a system. On works at an operating airport it is the first activity in the schedule, as in the teaching example.
For quality and configuration: EN 9100 and DO-178C
EN 9100 (AS9100 in the Americas) is the aerospace quality standard: it adds configuration and risk management. DO-178C does the same for airborne software. For the PM, every deliverable carries its evidence, and evidence also consumes schedule.
For measuring technology maturity: the TRL scale
The TRL (technology readiness level) scale runs from 1 to 9, originated at NASA and is now set out in ISO 16290. It helps decide whether a technology goes into a programme or is developed in parallel, with its own margin.
For scheduling and control: Gantt, CPM and earned value
Nothing new for you. The difference lies in what goes into the network: authority milestones, operational windows and supply lead times as real constraints. One common question remains: which certification is worth it?
PMP, PRINCE2 and other certifications: which one works in aviation?
None is specific to aviation: the most widespread ones all work, and their weight depends on the region and the type of organisation.
Who issues each certification
| Certification | Issued by | Focus | Where it carries most weight (qualitative) |
|---|---|---|---|
| PMP (Project Management Professional) | PMI (Project Management Institute) | Project management knowledge and practice (PMBOK Guide) | International and multinational employers; widespread in the Americas and the Gulf |
| PRINCE2 (PRojects IN Controlled Environments) | PeopleCert, which completed its acquisition of Axelos in 2021 | Process-based method, with roles and stage-by-stage control | Strong in the United Kingdom and Commonwealth countries, Europe and the public sector |
| IPMA certifications (levels A to D) | IPMA, through national associations (in Spain, AEIPRO) | Project manager competences | Europe |
The PMP is issued by PMI, which also publishes the PMBOK Guide (Project Management Body of Knowledge). PRINCE2 has belonged to PeopleCert since it completed the acquisition of Axelos in 2021. IPMA (International Project Management Association) certifies at four levels, managed in Spain by AEIPRO.
Is the PMP mandatory to work as an aviation project manager?
No. The PMP is not a legal requirement to work as a project manager in aviation. Some postings require it, especially in MRO, manufacturing and defence, and in English-speaking markets; others do not mention it. What postings never leave out is experience and knowledge of the regulated environment.
PMP or PRINCE2: which to choose depending on where you want to work
Neither is better in the abstract. For multinationals, the Americas or the Gulf, the PMP is the most recognised; for the United Kingdom, Commonwealth countries or the European public sector, PRINCE2 carries more weight. PMI periodically revises the PMBOK Guide and the exam: check the current edition and requirements on its official page. A certification brings method; what you lack, coming from another sector, is something else.
How to specialise in aviation projects if you come from another sector
Your method works; what you need is to know the terrain.
What you bring and what you lack
| What you bring | What you lack |
|---|---|
| Planning and control method | Aviation regulation and authorities |
| Cost and schedule control | Airport operations and operational windows |
| Stakeholder management | Safety and SMS |
| Project risk management | Certification and a documentation culture |
| Leadership of technical teams | The sector’s vocabulary and acronyms |

Frequently asked questions about the aviation project manager
What should you study to become an aviation project manager?
There is no single degree: people usually come from engineering (aeronautical, industrial, civil or telecommunications) or from management. What makes the difference is combining method, for example through a project management certification, with knowledge of the sector, through specialised training and experience in a regulated environment.
What software is used to calculate the critical path?
MS Project, Primavera P6 and other scheduling tools calculate the critical path from activities, durations and dependencies. For small projects a spreadsheet is enough. The software does the calculation; deciding what counts as a real dependency at an airport, such as an operational window or an approval, is still the PM’s job.
What happens if an activity on the critical path is delayed?
The end date slips, unless time is recovered later: by adding resources to critical activities (crashing) or by overlapping activities that were in sequence (fast-tracking). In aviation, this is done only where safety and the authority allow it, and never at the expense of testing.
Can an IT project manager work on aviation projects?
Yes. Airports and airlines run many systems projects: operations, baggage, passengers or airport collaborative decision making (A-CDM), which we explain in what A-CDM is. An IT PM brings the method; they will need to learn the regulated environment, airport operations and the documentation culture.
Conclusion: the method is yours, the context can be learnt
An aviation project manager does not use a different method: they use the same one in an environment where the regulator, operations and certification set the pace. That is why, in aviation, the critical activity is not always the longest one, but the one that cannot be compressed: a night window, an approval or transfer day.
