Question: What is the maximum allowed latency for the 3GPP system to enable a UTM to send route modification information to a UAS or to send a notification to a UAV controller?
Option 1: 1000 ms
Option 2: 2000 ms
Option 3: 3000 ms
Option 4: 500 ms
Explanation: The correct answer is 500 ms, as the 3GPP system shall enable a UTM to send route modification information to a UAS or to send a notification to a UAV controller with a latency of less than 500 ms. This ensures timely communication and efficient operation of unmanned aerial systems (UAS).
