During pre-flight preparations, you must anticipate the event of a lost link due to radio frequency communications failure. To be ready, you can program the communication to automatically switch to ________.

During pre-flight preparations, you must anticipate the event of a lost link due to radio frequency communications failure. To be ready, you can program the communication to automatically switch to ________.

• A. Satellite Communications
• B. Cellular Network
• C. Ground Control
• D. Backup Radio

Answer: (A)

The idea being tested is planning for a loss of the primary radio link by having an independent fallback path for control and telemetry. Satellite communications serve as the best backup because it uses a different path that doesn’t rely on local radio frequencies or line-of-sight to a ground station. If the main RF link is disrupted, automatically switching to a satellite link preserves the ability to issue commands and receive status, which is especially important for long-range or obstructed environments where ground-based links can fail or be degraded. Cellular networks depend on nearby towers and internet access, which may be unavailable or unstable in many flying areas. Ground control is the operator’s station on the ground; if the link is lost, you can’t rely on it to maintain communication. A backup radio is another terrestrial path, which may fail in the same environments or be subject to the same interference as the primary link. Satellite provides a more independent and resilient fallback, making it the best choice for a prepared, automatic switch.
