Where Airplanes are Born: How To Track Test Flights

  • Aircraft manufacturers conduct extensive test flights before delivery, and many of them can be tracked live on Flightradar24.

  • The article explains how to identify test registrations, callsigns, and flight patterns used during manufacturer testing.

  • Learn where major aircraft are built and how to follow their journey from factory to first customer flight.

Arriving on barges, train cars, or inside specially modified airplanes, components of new aircraft are shipped to massive, complex factories around the world, where Boeing, Airbus, and other aircraft manufacturers assemble new airplanes and test each one to make sure it’s in proper working order before delivering it to its new owner. Tracking new planes poses a challenge because callsigns and departure or arrival airports can be missing or the aircraft may be operating under a temporary registration. But with a few filters, it’s possible to see new airplanes being born.

Airbus

Airbus manufactures aircraft at multiple facilities in Europe, China and the United States. Airbus’ two main manufacturing complexes in Europe are in Toulouse, France, and Hamburg, Germany. In Toulouse, Airbus assembles its A320, A330, A350, and A380 aircraft. The location in Hamburg assembles members of the A320 family of aircraft (A318/319/320/321) as well as painting and final delivery of A380 aircraft. Airbus also assembles members of the A320 family in Tianjin, China. 

Airbus additionally has a plant in Mobile, Alabama in the United States, that is assembling the A320 and A220 families of aircraft. Speaking of the A220—originally developed as the C-series by Bombardier, Airbus has taken over the Mirabel plant in Canada from Bombardier, currently using it as its primarily manufacturing center for the A220.

Tracking new Airbus airplanes

There are a few ways to track new airplanes from Airbus. The first is by setting a callsign filter for “AIB”. This will filter for Airbus aircraft that are still undergoing testing before delivery to a customer. The second involves setting airport filters, which can capture both test and delivery flights.  To track just A220 aircraft, set an aircraft filter for either “BCS1” or “BCS3”. The airport codes for Airbus aircraft are:


To see the flights between factories in Toulouse and Hamburg, set an airport filter for both airports.

Boeing

Boeing manufactures their commercial aircraft at three main locations. Boeing’s Renton, Washington, facility manufactures its 737 variants, while its Everett factory produces the 747, 767, 777, and 787. Boeing produces additional 787s at its factory in Charleston, South Carolina.

It is common seeing Boeing B787 Dreamliner's doing their rounds in the skies above and beyond Charleston.

Tracking Boeing aircraft test flights

Tracking flights of new Boeing aircraft is slightly easier since Everett and Renton are quite close to each other. Setting a callsign filter for “BOE” and centering the map on the Seattle, Washington, area is a quick way to capture Boeing test flights. As for airport filters, the important codes for Boeing are:

  • Everett Paine Field—PAE
  • Boeing Field—BFI
  • Charleston—CHS

 

Other airports that may be helpful for tracking Boeing flights are Moses Lake (MWH) in eastern Washington and Victorville (VCV) in California. Boeing maintains test facilities at Moses Lake and many test flights pass through there on a regular basis. Victorville hosts some of Boeing’s aircraft for painting and modification.

The airplane-carrying airplanes

Both Boeing and Airbus maintain a fleet of specially modified cargo aircraft to transport aircraft components to their factories. Boeing uses modified 747-400 aircraft to carry sections of its 787 Dreamliners, which they’ve named the Dreamlifter. Its proper title is a bit less poetic as it is denoted as the Boeing 747-400LCF (large cargo freighter). To track Boeing’s Dreamlifters, set an aircraft filter for “BLCF”.

Airbus heavily modified five A300 aircraft to form its Beluga fleet. The Belugas are used to ferry parts, including wings and fuselage sections from fabrication centers in the United Kingdom, France, and Germany to final assembly in France, Germany, and Spain. To track Airbus’ Beluga fleet, set an aircraft filter for “A3ST”. 

The original Beluga family is being phased out in favor of the Beluga XL. If you want to track the successor to the old whale, use “A337” when filtering for aircraft type.

Using filters to your advantage

Tracking new aircraft can be exciting as it’s possible to watch a single airframe make it through multiple test flights and then delivery to the customer. Because tracking new aircraft manufacturing relies heavily on filters, our primer on filters may be helpful. Happy tracking!
