Before a single engine starts on a ferry flight, a week’s worth of coordination has already taken place. Permits have been applied for across multiple countries. Fuel stops have been confirmed. Crew documentation has been checked against every jurisdiction on the routing. And if the aircraft is operating without a full Certificate of Airworthiness, a certifying engineer has already signed off that it is safe to fly.
A ferry flight looks simple from the outside: an aircraft moves from A to B without passengers on board. In practice, it is one of the most logistically demanding operations in aviation. The planning layers (airworthiness documentation, overflight permits, fuel arrangements, crew compliance, and customs at every stop) all run in parallel and must be synchronised before departure.
This article explains what a ferry flight is, why they happen, and what the planning actually involves.
What Is a Ferry Flight?
A ferry flight is a repositioning flight with a specific purpose. It is not the same as an empty positioning sector flown daily to place an aircraft for its next revenue service. Ferry flights are a distinct category of operation, and they vary significantly in their complexity and documentation requirements.
The main types are:
- Delivery flights, where a new aircraft is flown from the manufacturer’s completion centre to its new owner or operator
- Maintenance and air test flights, where an aircraft is repositioned to or from a facility, or test-flown following scheduled work
- Transfer flights following a sale or change of ownership
- AOG recovery flights, where an aircraft is returned to base or a maintenance facility after going unserviceable at an outstation
- Repossession flights, which may involve an aircraft without full documentation and require fast, confidential handling
- Flights involving aircraft that are not fully airworthy, operating under a Permit to Fly rather than a standard Certificate of Airworthiness
What these operations share is that the aircraft is moving for a purpose other than carrying revenue passengers, and each type brings its own regulatory requirements, documentation obligations, and planning complexity. The sections below work through what that looks like in practice.
Why Ferry Flights Happen: Six Common Reasons
Operators, lessors, and owners arrange ferry flights for a range of reasons:
- Delivery of a new aircraft from the manufacturer’s completion centre to the owner’s base
- Repositioning to or from a maintenance, repair, or paint facility
- Transfer of an aircraft following a sale or change of ownership
- Recovery of an aircraft following an AOG (aircraft on ground) event at an outstation
- Repossession, which sometimes needs to be handled quickly and confidentially
- A test or inspection flight required before a sale or following scheduled maintenance
Each scenario has its own planning implications. A transatlantic delivery flight may involve multiple fuel stops, auxiliary tanks, and a crew change mid-route. A repossession requires confidential coordination and a fast turnaround. The requirements are not the same for every operation.
What Makes a Ferry Flight Different from a Standard Trip
A standard international trip involves flight planning, permits, and handling. A ferry flight involves all of that, plus additional layers that are easy to underestimate.
Airworthiness status is not always straightforward
Not every ferry flight requires special airworthiness documentation. If the aircraft holds a valid Certificate of Airworthiness, the operation proceeds normally.
The situation changes when the aircraft cannot meet its full airworthiness requirements. Common triggers include an overdue maintenance check, an unresolved airworthiness directive, or an aircraft being delivered ahead of formal acceptance. In these cases, a Permit to Fly is required.
The FAA calls this a Special Flight Permit. EASA’s equivalent is a Permit to Fly. Both are issued by the country of registration and authorise the aircraft to fly a specific route on a specific date, covering delivery, maintenance, or transfer of ownership. A certifying engineer must confirm the aircraft is capable of safe flight for that routing before the permit is issued.
Part of that assessment involves a review of the aircraft’s airworthiness directives. These are mandatory maintenance tasks issued by the relevant authority, and the aircraft’s records will show which are outstanding, which are overdue, and which have been deferred.
Before a Permit to Fly can be issued, a certifying engineer needs to work through those outstanding items and determine whether each one is compatible with a safe ferry flight in the aircraft’s current state. Some outstanding directives will have no bearing on the proposed operation. Others may ground the aircraft until the work is completed. That assessment takes time and cannot be rushed, which is another reason early planning matters on ferry operations involving reduced airworthiness.
One point that often catches operators out: even an aircraft with a valid Certificate of Airworthiness still requires overflight and landing permits for every international leg.
The permit picture for an aircraft ferry flight
Every country whose airspace you transit requires an overflight permit. Every airport you land at requires a landing permit. What makes a ferry flight more complex is the additional layer that applies when the aircraft is operating on a Permit to Fly or Special Flight Permit.
For a standard international flight, overflight and landing permits are processed through the permit departments of each country’s Civil Aviation Authority. Turnaround times are generally predictable and, for many countries, relatively quick.
For an aircraft operating on a Permit to Fly, the process is different. These applications are handled by airworthiness departments, not permit departments. The level of scrutiny is higher because the authority needs to be satisfied the aircraft is safe to operate in their airspace in a reduced airworthiness state. Processing times typically run from two to ten working days per country, and those offices work Monday to Friday, 0900 to 1700 only. There is no weekend processing and no out-of-hours escalation route.
On a multi-country routing, that adds up quickly. If the schedule involves six countries and any one of them takes the full ten working days, the entire operation waits. That timeline needs to be built into planning from day one, not treated as a detail to manage later.
For operators managing their own overflight and landing permits on a standard basis, ferry operations add significant additional workload because of the Special Authorisation layer and the volume of countries often involved on a single routing.
Documentation the aircraft must carry
- Aircraft registration certificate
- Certificate of Airworthiness or Permit to Fly (whichever applies)
- Insurance certificate, confirmed specifically for ferry operations. Many policies require advance notification.
- Crew licences, medicals, and type ratings appropriate to the aircraft
- EASA Form 1 or FAA Form 8130-3 if the aircraft has recently undergone maintenance
- Export Certificate of Airworthiness for manufacturer deliveries
- Valid overflight and landing permits for each leg
- Any Special Authorisations required for the routing
A documentation gap discovered at a remote fuel stop can ground the aircraft with no immediate resolution available.
Fuel Planning and Auxiliary Tanks on Long-Range Ferry Flights
On a long-range aircraft ferry flight, standard fuel capacity is often insufficient. A business jet being delivered from North America to the Middle East, or a light twin crossing the North Atlantic, will typically need more fuel than the standard tanks hold.
The solution is a ferry tank: a temporary fuel tank installed in the cabin for the duration of the flight. It sits near the aircraft’s centre of gravity and feeds directly into the existing fuel system. Pilots burn down the main tanks first, then transfer from the auxiliary once there is sufficient space.
Each installation requires regulatory approval specific to that aircraft registration. It is not a standard modification and must be tested before departure.
A few things operators need to understand about auxiliary tanks:
- Some operators increase total fuel capacity by 40 to 60 per cent using auxiliary tanks configured under ferry permits
- Where the auxiliary fuel load pushes the aircraft above its maximum certified take-off weight, a separate overweight permit is required
- That overweight authorisation covers only the weight of additional fuel, fuel-carrying equipment, and navigation gear. Nothing else.
Wind planning also matters. On a westbound North Atlantic crossing, headwinds can add materially to fuel burn. A competent flight planning operation models this before the routing is confirmed, not after permits have been filed.
Crew Requirements and Flight Time Limitations
Type rating requirements apply for larger aircraft types. The pilot in command must hold a current and valid rating on the type being ferried, issued or validated by the state of the aircraft’s registration. A pilot holding an EASA licence flying a US-registered aircraft, for example, would need a US flight crew validation certificate before acting as PIC. This is a separate requirement from the type rating itself and is frequently missed on short-notice operations.
EASA Flight Time Limitations (Subpart FTL under ORO.FTL) apply in full. A multi-leg routing with long sectors, time zone crossings, and overnight stops must be planned with rest requirements at each stage.
Crew visas are one of the most consistently overlooked elements of ferry flight planning. A routing through Africa, the Middle East, or parts of Asia may require transit visas at one or more fuel stops. Discovering this on arrival is a grounding event with no quick resolution.
What Can Go Wrong and Why It Matters
Ferry flights concentrate a large number of moving parts into a single operation. These are the risks that most frequently cause delays or groundings:
Permit validity window mismatches. A permit covers a specific date. A weather hold or tech issue pushes departure back and the permit expires, requiring refiling and, in some countries, restarting the processing clock.
Downstream permit gaps. The flight plan is filed but the permit has not reached the downstream FIR. The aircraft is refused entry or misses its overflight slot.
Crew documentation failures. A visa issue or licence discrepancy at a remote fuel stop grounds the aircraft with no available support nearby.
Ferry tank failures. Transfer systems must be tested before departure. Failures at sea are rare but have resulted in diversions and ditching.
AOG mid-ferry. A technical problem during the routing requires an approved maintenance provider, possibly replacement parts, and a new or extended permit, all managed from a location outside the operator’s normal network.

Getting a Ferry Flight Right: What the Planning Actually Covers
Operators who manage ferry flights well treat them as a distinct operation, not a complicated version of a normal trip.
Flightworx’s ferry and delivery service covers every element of that process: route planning, permit coordination including Special Authorisations for aircraft on a Permit to Fly, fuel sourcing, handling confirmation, crew travel logistics, and a Trip Cost Estimate that sets out all expected costs before the operation is confirmed.
The service covers aircraft with full or limited airworthiness, including those on a Permit to Fly, as well as repossession operations requiring confidential handling.
Ferry flights where specialist support adds the most value tend to involve:
- Long-range or transoceanic routing with multiple fuel stops
- Aircraft operating on a Permit to Fly
- High-complexity permit regions such as Africa, the Middle East, or CIS states
- Time-sensitive scenarios including AOG recovery or weather-window departures
- Repossession operations requiring discreet coordination
If your aircraft needs to be in a different location, the quality of the support behind the flight determines whether it happens on schedule or not.

Frequently Asked Questions
What is a ferry flight in simple terms?
A ferry flight moves an aircraft from one location to another without passengers or cargo on board. The crew reposition the aircraft for delivery, maintenance, a change of ownership, or recovery after an AOG event.
Do ferry flights always need a special permit?
Not always. If the aircraft holds a valid Certificate of Airworthiness, no special airworthiness permit is required. However, all international legs require overflight and landing permits regardless of airworthiness status.
What is a ferry tank and when is one used?
A ferry tank is a temporary auxiliary fuel tank fitted in the cabin to extend range. It is used when standard fuel capacity is insufficient for the routing, most commonly on long-range or transoceanic delivery flights. Each installation requires regulatory approval specific to that aircraft.
How long does it take to arrange a ferry flight?
It depends on the routing and airworthiness status. Special Authorisations for aircraft on a Permit to Fly can take up to 20 days to process. Planning should begin well in advance.
Can Flightworx support ferry flights for aircraft on a Permit to Fly?
Yes. Flightworx handles ferry and delivery flights for aircraft with full or limited airworthiness, including those on a Permit to Fly, covering flight planning, permits, fuel, ground handling, and crew logistics under one point of contact.
