About ...


... me
In 1982 I graduated as aeronautical engineer from Delft University. For most of my working life I have been employed at the Royal Netherlands Aerospace Centre (NLR) in Amsterdam, working on helicopter related topics. Activities range from flight performance to flying qualities, from helicopter pre-design to flight testing, from operational support to flight simulations, from flight safety to teaching drone operators, etc.
 
My hobby started as an aircraft spotter. Once I had decided 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.
... my 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 165 500 civil rotorcraft registrations for more than 93 550 individual rotorcraft. Over the years the database has been growing with an average annual increase of about 5350 civil rotorcraft registrations and about 3000 individual rotorcraft.
 
Exclusions
‘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 with lifting propellers. Furthermore, unmanned rotorcraft below 150 kg are also excluded.
... my website
The Rotorspot website publishes data extracted from the database. On this website one can find current (active) and historical (complete) civil rotorcraft registers for every country in the world, complete production lists for a growing range of rotorcraft types, and, last but not least, a searchable rotorcraft database. The main purpose of this website is to provide quick access to rotorcraft type, identity, registration and history. E.g. when you have a registration and are looking for the correct type or identity, the website will provide it. Based on that first step, one then can make further research using other, more elaborate sources.
 
The first release of the Rotorspot website was in 1999, with the switch to the own domain at www.rotorspot.nl being made in 2009. As far as I am aware, this website's contents do not duplicate anything publicly available in book form or on other websites. Some national aircraft registers or rotorcraft production lists are published in books and on websites, but in different formats.
 
The Rotorspot website requires JavaScript and has been tested for proper displaying in various browsers, like Chrome, Edge, Firefox, Internet Explorer, Opera and Safari. All CSS, HTML and PHP code on the website has been validated for standards compliance using appropriate tools. Although this guarantees a website without coding format errors, it does not guarantee an error-free appearance in different browsers. So, if you do encounter problems of any kind, feel free to inform me and I will do my best to correct the situation as soon as possible.
