ANAC registration mark reservation: what it is and what the queue reveals about the market

The mechanics, in one line

If the aircraft never arrives, the reservation expires (or gets renewed under the rules) and the mark goes back into the pool. In the public lookup, a reserved registration shows up with no operational aircraft attached to it: it is registered intent, not an airplane in flight. How to identify each status is covered in our guide to the RAB lookup.

Who reserves, and why: the buyer of a new aircraft who wants the mark waiting at the factory door; the importer in the middle of deregistering the aircraft abroad (a process we break down in our article on importing); the group standardizing its fleet with a block of matching marks; and the legitimate vanity of flying with your own initials, something the PS series, opened in 2020, turned into a genuine phenomenon.

The queue, measured right now

To put it in perspective: the queue is roughly a fifth the size of the country's operational turbine business fleet. And it is not static: it converts into a registration (the outcome the market is waiting for), renews, or expires, every week.

The mark request happens months before the airplane ever operates. Whoever tracks the queue reads the market in the future tense.

The R66 case: when the queue shouted

The example that needs no theory is the one on this article's cover. In the June 2026 RAB Radar, the Robinson R66 helicopter showed up with 452 reserved marks associated with the model: a pipeline that anticipates years of deliveries into Brazil, visible in the registry before any hangar could notice it (source: RAB Radar, Helicopters, June 2026, published in Jet Tracker's reports).

Anyone selling parts, insurance, hangar space or training for that model had, right there for free, a map of future demand. That is the kind of read the aggregate queue cannot give you, but the queue by model can: the granular tracking lives on each model's page in the catalog.

How to read it (without fooling yourself)

A reservation is not an acquisition. It is low-cost intent. Some of it expires without ever becoming a registration. The signal lives in volume and trend, never in any single request.

A reservation does not add to the fleet count. A serious count separates operational registrations from reservations and deduplicates by serial number, because the same airplane can have an operational mark and a reservation at the same time. Mixing the two is the fastest way to inflate a fleet count in a PowerPoint deck.

A registry movement is not a sale. The registry shows the change; the contract behind it (a purchase, a corporate reorganization, a lease) is not public. We report registry movements as what they are: movements.
