Watching planes is a huge hobby all over the world. It is a kind of collecting hobby where people search for planes at different airports and document or take photos of what they find. Aircraft observers often visit airports while traveling and spend time observing aircraft movements.
Many people may not be able to fly a plane, sometimes for physical/medical reasons, or maybe just for financial reasons, flying is a very expensive hobby. People often turn to aircraft surveillance to participate in flights for free. You can consider the high-tech civil aviation regulations via https://www.bcaa.bm/.
To provide observers with the information they need, they need access to the best research tools, including the ability to simply look up information in aircraft registration databases.
The aircraft registration database contains information relating to aircraft registration marks. Often, civil aviation authorities make registration information publicly available, this information including elements such as the registration mark itself, the aircraft manufacturer, year of manufacture and its current owner and/or operator.
If you see an airplane, look for its license plate, always under the wing and on the vertical stabilizer or propeller. Then you need a good registration database as a reference, you will find a good database with which you can search as many countries as possible in one place, the database should also be easy to use, fast and of course mobile.
