Which of the following is an advantage of secondary radar?

Choosing that secondary radar is less vulnerable to blind spots highlights a key strength of this technology in air traffic control. Secondary radar, which relies on actively interrogating transponders on aircraft to gather information, improves detection capabilities in areas where primary radar might struggle, such as in mountainous terrains or when dealing with smaller aircraft that may not be effectively tracked by primary systems alone. This advantage directly contrasts with primary radar, which can have blind spots due to the nature of its signal bounce-off mechanism. While secondary radar's reliance on transponders means it may still face challenges in scenarios where transponders are turned off or malfunctioning, it generally provides a more comprehensive and reliable picture of aircraft in the airspace. In evaluating the other options, it's clear that secondary radar does not provide weather information, as that is a function typically associated with specific weather radar systems. It also cannot display all aircraft regardless of transponder since transponder-equipped systems can only track those with functioning transponders. Lastly, secondary radar is known for its longer range capabilities compared to primary radar, which is the opposite of the last choice stating it has a shorter range. Thus, the focus on the reduced vulnerability to blind spots helps underscore why this characteristic is a sought-after advantage in the
