I graduated as aeronautical engineer from Delft University in Sep-1982. From Feb-1985 until my retirement in Jul-2021 I was employed at the Royal Netherlands Aerospace Centre (NLR) in Amsterdam, working on rotorcraft related topics. Activities ranged from flight performance to flying qualities, from pre-design to flight testing, from operational support to flight simulations, from flight safety to teaching drone operators, etc. My hobby started as being an aircraft spotter. Once the decision was made to concentrate on helicopters, it was a small step to start building a civil rotorcraft registrations database. At first just for The Netherlands, then also for Belgium and Luxembourg, and the rest of Europe. Soon this evolved into the worldwide Rotorspot database.
... the database
The Rotorspot database contains worldwide registration data for civil (and to a lesser extent for military) rotorcraft. The database includes information on registration, rotorcraft type, construction number, registration history, and final fate. There is no owner/user/operator information in the database and data are strictly used for non-commercial purposes. The database is continuously updated with information from various sources. Currently, the database contains more than 174 660 civil rotorcraft registrations for more than 97 930 individual rotorcraft. Over the years the database has been growing with an annual increase of about 4900 civil rotorcraft registrations and about 2700 individual rotorcraft.
Definition‘Rotorcraft’ to this respect means a heavier-than-air aircraft that depends principally for its support in flight on the lift generated by one or more rotors. Therefore, the Rotorspot database and website exclude all aircraft types with lifting propellers. Furthermore, unmanned rotorcraft below 150 kg are excluded.
... the website
The Rotorspot database and website are a private initiative and have no links with commercial organisations. Rotorspot.nl reserves the right not to accept any liability, nor to be responsible for the content of external links. All Rotorspot registration data can be used freely (with due credit to www.rotorspot.nl), but strictly for non-commercial applications.
