Frequently Asked Questions on ch-aviation - Ownership

ch-aviation offers you a very user friendly interface targeted at consumers, professionals and enthusiasts alike to search and analyze aircraft ownership details. We have answered the most frequently asked questions below and hope this will address any immediate questions you may have on our fleet ownership section of the site:


How do I use the ownership search form?

You have four different search options to choose from:

  • Search by Lessor: Select the Continent (and the Country) for which you would like to display all Lessors based on that Continent or in that Country
  • Search by Aircraft Portfolio: Select the Aircraft Details you would like to see in Lessors’ Portfolios. You can search by Market Group, Manufacturer, Aircraft Family, Aircraft, Type, Model and/or Variant.
  • Search by Engines: To narrow down your Lessor portfolio search, select the engines you would like to display from the dropdown lists.
  • Filters: Use the Aircraft Role dropdown menu to choose the particular aircraft roles to perform or narrow down your search. You may opt to list the Lessors with a particular number of aircraft in the portfolio by using the Aircraft in Portfolio Filter (from and to numbers to be entered, i.e. from 5 to 20 aircraft). The Aircraft in Country Filter will provide you with Lessor portfolios that include aircraft registered in the country of choice.


What are registrations and what about C/N and MSN?

Every aircraft is assigned a registration when it is added to the civil aircraft register of a country that is a combination of a country prefix and a registration/tail number. For example, A6 is the country prefix for the United Arab Emirates; A6-ETD is a registration of a Boeing 777-300ER of Etihad Airways.

C/N stands for construction number, for most manufacturers these numbers are assigned in ascending order by production date. Some manufacturers such as Boeing also assign a Manufacturer Serial Number in addition.

Please note that any other aircraft types not listed above will not be displayed in airline fleet list summaries or detail displays and by policy we will only add other aircraft types once we have the entire production list available up to ch-aviation standards. We are however constantly working on the addition of more aircraft types and will advise once they have been made available.

* Only active aircraft are listed.


Are all aircraft ordered but not yet delivered displayed in the fleet overview per carrier?

It is ch-aviation policy to only start displaying aircraft in fleet lists of carriers once either the construction number (c/n) or manufacturer serial number (MSN) is known, so the answer is no. The time period before delivery when we typically learn about the c/n and/or MSN assignments for aircraft orders varies by manufacturer.


What does SPV stand for?

SPV stands for Special Purpose Vehicle.


How can I report errors found or updates I would like to provide to the ch-aviation team?

We are maintaining records for tens of thousands of aircraft and use a wide range of very different types of sources throughout the world to keep them as up to date as possible. Should you still come across an error, omission or have an update for us, you can simply click on the envelope behind each aircraft to immediately send the responsible fleet list editor at ch-aviation a message.
