True or False: Radar monitoring is required for all IFR aircraft on all random RNAV routes.

Radar monitoring is indeed required for all IFR aircraft operating on random RNAV routes. This requirement ensures that air traffic controllers maintain real-time situational awareness of aircraft positions, which is crucial for safe air traffic management. Random RNAV routes, which may not follow traditional navigation aids or assigned routes, can lead to less predictable traffic patterns. Therefore, the use of radar is essential to maintain separation between aircraft, manage airspace efficiently, and enhance overall safety.

Although there are some specific situations where radar monitoring may not be as critical (like in certain types of airspace for specific operations), the general rule is that all IFR flights on random RNAV routes must be tracked by radar to ensure compliance with safety regulations and protocols.
