About LADD (Limited Aircraft Data Display)
LADD frequencies refer to specific radio frequencies used by aircraft to communicate with each other directly during flight. LADD stands for **Limited Aircraft Data Display**, a program initiated by the FAA (Federal Aviation Administration) to enhance privacy for aircraft operators by limiting the public display of aircraft tracking data.
Pilots or operators participating in the LADD program can request that their flight details not be shown on public websites like FlightAware or ADS-B Exchange. However, air traffic controllers and other authorized users can still access this information.
The term "LADD frequencies" may refer to radio frequencies commonly used in conjunction with the LADD program to allow for coordination between aircraft (not via ground control). In general aviation, **VHF (Very High Frequency)** communication channels (118 MHz to 137 MHz) are used for air-to-air communications, but there isn't a specific LADD frequency outside of this broader spectrum.
In Canada, you generally need a **Restricted Operator Certificate with Aeronautical Qualification (ROC-A)** to legally operate a radio and transmit on aviation frequencies, including LADD frequencies.
The ROC-A is required by **Transport Canada** for anyone who uses an aviation radio to ensure proper use and understanding of radio communications, which is critical for safety. The ROC-A license covers the operation of all aviation frequencies, including LADD (air-to-air) frequencies used by pilots.
To summarize:
- Yes, you need a radio operator's certificate (ROC-A) to legally transmit on LADD frequencies in Canada.
- The ROC-A ensures that the operator has been trained in proper radio communication protocols.
