Aircraft Delivery Made Simple
You have an aircraft that needs to move.
Maybe you:
- Just purchased an airplane in another state
- Sold an aircraft to a buyer across the country
- Need an aircraft moved to maintenance
- Need a plane delivered to an avionics or paint shop
- Need a flight-school aircraft repositioned
- Need an aircraft moved for an annual inspection
- Need a fleet aircraft relocated
- Simply don’t have the time to move the airplane yourself
Ferry Flight USA makes the process straightforward.
From your first quote request through aircraft pickup and final handoff, we coordinate the pilot, aircraft, route and mission logistics required for qualifying aircraft ferry flights throughout the United States.
The Ferry Flight USA Process
1. Request Your Ferry Quote
2. We Review the Aircraft & Mission
3. We Match the Pilot or Crew
4. We Coordinate Aircraft Pickup
5. The Ferry Flight Begins
6. Your Aircraft Is Delivered
That’s the simple version.
Here’s what happens at each stage.
Step 1 — Request Your Aircraft Ferry Quote
The process begins with information about the aircraft and mission.
You do not need to create a detailed flight plan for us.
Start with the basics.
Tell Us About the Aircraft
Provide:
- Aircraft manufacturer
- Aircraft model
- Aircraft variant when applicable
- Year if known
- Registration number / N-number
For example:
Cessna 172S
Piper PA-28R Arrow
Cirrus SR22
Beechcraft Baron
Cessna 421
Piper Aerostar
The exact aircraft matters because pilot qualifications, insurance requirements, cruise speed, fuel range and mission complexity can vary significantly from one model to another.
Tell Us Where the Aircraft Is
Provide:
Departure airport
Ideally include the airport identifier.
For example:
KSDL — Scottsdale Airport
rather than simply:
Phoenix
This allows us to begin evaluating the actual ferry route and pilot travel logistics.
Tell Us Where the Aircraft Is Going
Provide:
Destination airport
This may be:
- Your home airport
- Maintenance facility
- Avionics shop
- Paint shop
- Engine shop
- Aircraft dealer
- Buyer location
- Flight-school base
- Corporate base
If you are unsure which nearby airport is most appropriate, provide the intended city or facility and we can evaluate the mission.
Tell Us When the Aircraft Will Be Ready
Provide:
- Earliest pickup date
- Desired delivery timeframe
- Any important scheduling considerations
Exact delivery timing remains subject to factors including:
- Aircraft readiness
- Pilot availability
- Weather
- Maintenance
- Insurance approval
- Mission requirements
The earlier we know about the mission, the more time we have to coordinate an appropriate pilot and travel plan.
Tell Us Why the Aircraft Is Moving
This helps us understand the mission.
Examples:
Newly purchased aircraft
Aircraft sale
Annual inspection
Maintenance
Avionics installation
Paint shop
Engine shop
Seasonal relocation
Flight-school fleet repositioning
AOG recovery
Corporate repositioning
Mission purpose can affect pickup coordination, aircraft condition and delivery requirements.
Tell Us About the Aircraft’s Current Condition
We need accurate information.
Let us know:
- Is the aircraft currently airworthy?
- Is the annual current?
- Are there known discrepancies?
- Has the aircraft been sitting?
- Is it currently in maintenance?
- Are any avionics inoperative?
- Are there known engine, electrical or landing-gear issues?
Known problems should be disclosed before pilot travel.
This allows us to determine whether the aircraft appears appropriate for a normal ferry mission or whether additional maintenance or a Special Flight Permit may need to be considered.
AIRCRAFT PRE-DELIVERY CHECKLIST
Tell Us About Insurance Requirements
If you already know the aircraft’s pilot insurance requirements, include them.
These might involve:
- Minimum total time
- Make/model time
- Multi-engine time
- Retractable-gear experience
- Tailwheel time
- Turbine time
- Type rating
- Recurrent training
- Named-pilot approval
If your policy requires insurer approval of the ferry pilot, that should be handled before pilot dispatch.
AIRCRAFT INSURANCE REQUIREMENTS
Step 2 — We Review the Mission
Once Ferry Flight USA receives your request, we evaluate the complete mission.
This is more than measuring the straight-line distance between two airports.
We may consider:
Aircraft Type
What aircraft are we moving?
Aircraft Complexity
Is it:
- Fixed gear
- Retractable
- High performance
- Tailwheel
- Multi-engine
- Pressurized
- Turbine
- Type-rated
Distance
How far does it need to travel?
Aircraft Speed
Aircraft cruise speed affects:
- Flight time
- Number of pilot days
- Fuel stops
- Hotel requirements
Aircraft Range
Range affects route and fuel-stop planning.
Pilot Requirements
What ratings, endorsements and aircraft experience are appropriate?
Insurance Requirements
Does the policy establish specific pilot minimums?
Route
What general routing considerations are likely?
Weather
Are there major weather trends or seasonal concerns?
Pilot Travel
How will the pilot reach the aircraft and get home after delivery?
Aircraft Status
Is the aircraft ready to move?
Every Mission Is Different
Consider these missions:
Mission A
Cessna 172
Florida to Georgia
Mission B
Cirrus SR22
California to Florida
Mission C
Cessna 421
Texas to New York
Mission D
Piper Cub
Washington to Arizona
All four are aircraft ferry flights.
But they require very different:
- Pilots
- Routes
- Fuel planning
- Travel logistics
- Insurance considerations
- Delivery schedules
That is why Ferry Flight USA evaluates each mission individually.
Step 3 — We Determine the Pilot Requirements
Before assigning a pilot, we determine what qualifications the aircraft and mission require.
Potential considerations include:
- Airplane category and class
- Single-engine or multi-engine rating
- Instrument rating
- Complex endorsement
- High-performance endorsement
- Tailwheel endorsement
- Type rating
- Total flight time
- PIC experience
- Make/model experience
- Time in type
- Multi-engine time
- Pressurization experience
- Turbine time
- Mountain experience
- Recurrent training
The goal is not to find:
Any pilot who can legally fly the aircraft.
The goal is to identify:
A pilot whose qualifications and experience fit the aircraft and mission.
Step 4 — We Match the Aircraft With an Appropriate Pilot or Crew
Once the pilot requirements are understood, Ferry Flight USA can evaluate available pilots.
Pilot matching may consider:
Aircraft Experience
Does the pilot have relevant experience in the model or similar aircraft?
Insurance Compatibility
Does the pilot satisfy the applicable requirements provided for the aircraft?
Geography
Where is the pilot located relative to the aircraft?
Availability
Does the pilot’s schedule fit the mission?
Route Experience
Does the mission involve:
- Mountain terrain
- Alaska
- Long-distance cross-country
- Remote airports
- Specialized operations
Crew Requirements
Does the aircraft require:
- One pilot
- Two pilots
- Type-rated captain
- Qualified second-in-command
Pilot assignment is mission-specific.
A pilot who is ideal for one aircraft may not be appropriate for another.
Step 5 — Insurance Compatibility Is Confirmed When Required
Aircraft insurance can affect pilot assignment.
A policy may contain:
- Open pilot requirements
- Named-pilot requirements
- Make/model minimums
- Training requirements
- Type-rating requirements
If specific insurer approval is required, pilot qualification information can be provided for evaluation.
The aircraft owner remains responsible for confirming actual policy coverage and approval with the insurance carrier or aviation insurance broker.
Ferry Flight USA does not assume that FAA pilot qualifications automatically satisfy every insurance policy.
AIRCRAFT INSURANCE REQUIREMENTS
Step 6 — Your Ferry Quote Is Finalized
Once the mission is understood, pricing can be based on the actual aircraft and logistics.
Potential cost factors can include:
- Pilot professional fee
- Distance
- Aircraft speed
- Number of pilot days
- Airline positioning
- Return travel
- Hotels
- Ground transportation
- Crew requirements
- Mission complexity
Aircraft operating expenses may also need to be addressed depending on the agreement.
These can include:
- Fuel
- Oil
- Airport fees
- Parking
- Other aircraft operating costs
The quote should make the pricing structure clear before the mission begins.
Step 7 — The Mission Is Scheduled
Once the mission is accepted, the ferry operation is scheduled around:
- Aircraft availability
- Pilot availability
- Insurance
- Expected weather
- Pickup logistics
For newly purchased aircraft, pilot travel should ideally be coordinated around actual closing and aircraft readiness.
For maintenance aircraft, pickup should be based on actual completion—not simply an estimated completion date.
Step 8 — We Coordinate Pilot Positioning
The ferry pilot has to reach your aircraft before the aircraft can go anywhere.
Depending on location, pilot positioning may involve:
- Commercial airline
- Rental car
- Rideshare
- Train
- General aviation flight
- Ground transportation
The pilot’s travel plan is coordinated around the aircraft’s location and expected availability.
Remote airports may require additional ground transportation.
Step 9 — We Coordinate Aircraft Pickup
Before pilot arrival, we work to establish the practical pickup details.
These can include:
- Exact aircraft location
- FBO
- Hangar
- Gate access
- Keys
- Seller contact
- Broker contact
- Maintenance contact
- Fuel status
- Aircraft condition
- Destination information
A professional delivery begins with an organized pickup.
AIRCRAFT PRE-DELIVERY CHECKLIST
Step 10 — The Aircraft Owner Confirms Readiness
Before pilot travel, the aircraft owner, seller, broker or appropriate local representative should confirm that the airplane is actually ready.
Examples include:
☐ Aircraft accessible
☐ Keys available
☐ Maintenance complete
☐ Required inspections current
☐ Insurance active
☐ Pilot approved where required
☐ Known discrepancies disclosed
☐ Aircraft documentation available
☐ Purchase closing complete where applicable
☐ Seller has released the aircraft
This can prevent avoidable pilot travel delays.
Step 11 — The Pilot Arrives at the Aircraft
After reaching the departure airport, the pilot coordinates access with the appropriate:
- Owner
- Seller
- Broker
- Dealer
- Maintenance shop
- FBO
- Aircraft manager
The pilot reviews the aircraft for the intended mission and completes the appropriate preflight preparation before departure.
Step 12 — Aircraft Condition Is Reviewed
The pilot evaluates the aircraft for the intended operation.
Potential items can include:
- Aircraft general condition
- Fuel
- Oil
- Tires
- Brakes
- Flight controls
- Visible leaks
- Aircraft documentation
- Known discrepancies
This should not be confused with a formal aircraft pre-buy inspection or annual inspection unless a separately authorized maintenance professional is performing that work.
The ferry pilot is evaluating the aircraft for the proposed flight.
What If the Pilot Finds a Problem?
If a discrepancy is discovered, departure may be delayed.
Depending on the issue, the next step may involve:
- Local mechanic
- Maintenance inspection
- Repair
- Troubleshooting
- Battery service
- Tire replacement
- Ferry-permit evaluation
Aircraft condition comes before the schedule.
SAFETY & STANDARDS
Step 13 — The Pilot Plans the Ferry Flight
Once the aircraft is ready, the pilot develops the operational flight plan.
Planning may consider:
- Weather
- Winds
- Terrain
- Fuel
- Aircraft range
- Airspace
- Airport suitability
- Runway length
- Airport elevation
- Fuel availability
- Alternate airports
- Maintenance resources
- Overnight stops
The shortest route is not always the best route.
Step 14 — Fuel Stops Are Planned
Long-distance aircraft delivery may require multiple fuel stops.
The pilot selects stops based on factors such as:
- Aircraft range
- Fuel burn
- Winds
- Required reserves
- Runway
- Weather
- Fuel availability
- Route efficiency
The cheapest fuel airport is not always the best operational choice.
Step 15 — Weather Is Evaluated
Weather is one of the most important variables in any ferry mission.
Potential concerns include:
- Thunderstorms
- Icing
- Strong winds
- Low ceilings
- Fog
- Turbulence
- Mountain weather
- Winter storms
- Tropical weather
The pilot may choose to:
- Delay
- Depart earlier
- Reroute
- Stop early
- Add an overnight
Weather decisions remain operational decisions—not customer scheduling decisions.
Step 16 — The Ferry Flight Begins
Once:
- Aircraft is ready
- Pilot is ready
- Insurance requirements are addressed
- Weather is appropriate
- Flight planning is complete
the ferry flight begins.
The airplane starts its journey toward the destination.
Step 17 — The Pilot Adjusts the Plan as Needed
Long-distance ferry flying requires flexibility.
Conditions can change after departure.
The pilot may need to adjust:
- Route
- Fuel stop
- Altitude
- Overnight location
- Departure time the next morning
Reasons can include:
- Weather
- Winds
- Fuel availability
- Airport closures
- Mechanical issues
The objective is successful delivery—not rigid adherence to a route created the night before.
Step 18 — You Receive Mission Updates
Aircraft owners naturally want to know where their aircraft is.
Appropriate updates can include:
Pilot arrived at the aircraft
Aircraft departed
Fuel-stop progress
Weather delay
Unexpected maintenance issue
Overnight location
Expected delivery timing
Aircraft delivered
The frequency and type of communication can depend on the mission.
You should not have to wonder whether your aircraft ever left the departure airport.
Step 19 — Overnight Stops When Necessary
Some missions require multiple days.
Overnight stops may occur because of:
- Distance
- Aircraft speed
- Weather
- Winds
- Daylight
- Pilot workload
A slower piston aircraft may require several flight days for a coast-to-coast delivery.
A faster aircraft may cover the same distance much more quickly.
Stopping overnight is a normal part of long-distance aircraft delivery.
Step 20 — Unexpected Maintenance Is Managed Appropriately
Aircraft sometimes develop issues during delivery.
Potential examples include:
- Battery
- Starter
- Tire
- Brake
- Alternator
- Avionics
- Engine
- Oil leak
If a maintenance issue occurs, the pilot may:
- Land
- Contact the owner
- Coordinate local maintenance
- Stop overnight
- Resume when appropriate
The delivery timeline may change.
Aircraft condition remains the priority.
Step 21 — Destination Arrival Is Coordinated
Before final arrival, the pilot should know:
- Where the aircraft will park
- Who is receiving it
- FBO
- Hangar location
- Key instructions
- Destination contact
Delivery may be made to:
- Aircraft owner
- Buyer
- Broker
- Dealer
- Maintenance facility
- Flight school
- Aircraft manager
- Corporate flight department
Step 22 — The Aircraft Is Delivered
Upon arrival, the pilot parks and secures the aircraft according to the agreed instructions.
The aircraft may be:
- Handed directly to the owner
- Left with an FBO
- Delivered to a maintenance facility
- Placed in a hangar
- Delivered to a buyer
- Delivered to a flight school or operator
The final handoff closes the operational portion of the ferry mission.
Step 23 — Final Mission Information Is Communicated
Where appropriate, the completed delivery may include information such as:
- Delivery confirmation
- Arrival time
- Destination
- Aircraft location
- Key handoff
- Relevant mission notes
- Any discrepancies encountered during flight
This gives the customer a clear conclusion to the aircraft’s journey.
How Newly Purchased Aircraft Delivery Works
Just bought an aircraft in another state?
The process typically looks like:
1. Send Us the Aircraft
Make, model, N-number and location.
2. Tell Us Where Home Is
Provide the destination airport.
3. Provide Expected Closing Date
We can begin evaluating pilot requirements before closing.
4. Arrange Insurance
Make sure coverage and ferry-pilot requirements are addressed.
5. Complete Closing
Seller releases the aircraft.
6. Ferry Pilot Picks Up the Airplane
Pickup is coordinated with seller, broker or dealer.
7. Aircraft Is Delivered
The airplane arrives at your selected destination.
You do not need to spend several days flying across the country simply to retrieve your purchase.
NEWLY PURCHASED AIRCRAFT DELIVERY
How Maintenance Ferry Flights Work
Need your airplane moved to a shop?
The process can look like:
1. Schedule the Maintenance Facility
Confirm the shop and appointment.
2. Request the Ferry Mission
Provide aircraft, origin and maintenance-shop destination.
3. Review Aircraft Status
Confirm the aircraft can make the planned flight.
4. Evaluate Ferry Permit Requirements if Necessary
An aircraft that cannot complete a normal flight may require an FAA Special Flight Permit.
5. Assign the Pilot
Match the aircraft and insurance requirements.
6. Deliver the Aircraft to the Shop
The maintenance facility receives it.
7. Return Delivery
After maintenance, another ferry flight can be coordinated if needed.
How Ferry Permit Flights Work
Some aircraft need to reach maintenance but cannot currently operate under normal airworthiness requirements.
A qualifying aircraft may be eligible for an FAA Special Flight Permit.
The process can involve:
- Aircraft evaluation
- Maintenance involvement
- FAA application
- FAA operating limitations
- Insurance review
- Qualified pilot
- Route planning
- Ferry flight to the approved destination
The FAA determines whether a Special Flight Permit can be issued.
Ferry Flight USA can coordinate qualifying operational ferry missions once the required authorization and aircraft readiness are addressed.
How Broker & Dealer Deliveries Work
Aircraft brokers and dealers frequently need delivery support after a sale.
A typical mission can involve:
Broker or dealer provides aircraft information
↓
Buyer destination is confirmed
↓
Closing occurs
↓
Insurance and pilot requirements are addressed
↓
Ferry Flight USA coordinates pilot
↓
Pilot collects aircraft
↓
Aircraft delivered to buyer
This can allow aviation businesses to sell aircraft nationwide without requiring internal personnel to handle every delivery.
DEALER & BROKER FERRY SERVICES
How Flight-School Aircraft Repositioning Works
Flight schools may need aircraft moved for:
- Purchases
- Sales
- Maintenance
- 100-hour inspections
- Annual inspections
- Engine work
- Avionics
- Fleet transfers
Instead of taking an instructor away from student flying for several days, a professional ferry pilot can handle the aircraft movement.
