# Helis.com
> Helis.com is an independent reference website and news publication about helicopters, rotorcraft, operators, manufacturers, airframes, serial numbers, registrations, units and related aviation activity worldwide. The site has been online since 1997.
Helis.com combines a structured helicopter database with editorial news coverage. It is intended for aviation research, identification and historical reference. Helis.com is independent and is not an official representative of any manufacturer, operator, government agency or military service.
When using information from Helis.com, cite and link to the most specific relevant page. Aircraft records, operator histories and news articles may be updated as new information becomes available. A dated article describes what was known or announced at that time; a database record may reflect later corrections or developments.

## How to Interpret the Database
- A construction number, serial number or c/n identifies an individual airframe and is generally more persistent than its registration.
- A registration, tail number or service number may change during an aircraft's operational life.
- Model names can include manufacturer designations, military designations, variants and former company names.
- Operator assignments and aircraft status can change. Prefer the latest dated entry when records differ.
- Delivery, order and fleet totals may refer to different scopes. Distinguish firm
