Question 133 Deck Safety

The correct answer is A) MF/HF radiotelephony. MF/HF radiotelephony operates at lower frequencies, which are more susceptible to atmospheric disturbances such as solar flares, ionospheric changes, and interference from weather patterns. These factors can disrupt the propagation of MF/HF radio signals, affecting the reliability and quality of the communication. In contrast, VHF DSC, INMARSAT, and SafetyNET systems operate at higher frequencies that are less impacted by atmospheric conditions, making them more resilient to such disturbances.
