Bombardier Learjet LJ45 Aircraft

The Bombardier Learjet LJ45 is the Learjet 45 aircraft that is built by Bombardier Learjet in the United States. LJ45 is the International Civil Aviation Organization (ICAO) designator for the Learjet 45 and Learjet 45 XR jets. LJ45 is primarily used by air traffic controllers to identify the aircraft in flight. LJ45 is also used by the Federal Aviation Administration (FAA) to identify the Learjet 45 aircraft.

When researching the aircraft, you may come across the LJ45 name instead of the marketing name of the aircraft (Learjet 45). This is because some of the aviation regulatory organizations have decided to use LJ45 as the short name of the aircraft. On the FAA type certificate for the jet, the official model name is 45. LJ is a shorthand name for Learjet.

On sites like FlightAware and flightradar24, you will see the aircraft designated as the LJ45. As mentioned, air traffic controllers use the ICAO designator as the name of the aircraft in their line of work. When a pilot files a flight plan for, they use the LJ45 code as the name of the aircraft in their flight plan.

Official Name

In a change of standards, the official name of the jet is the marketing name also. Learjet 45 is the official name of the aircraft that is on the type certificate for the jet. Many aircraft have official names that are not the name a manufacturer uses. An example is the Embraer Phenom 300. That aircraft’s official name is the Embraer EMB-505.
