In which situation might a receiver call for a breakaway?

A receiver might call for a breakaway specifically when there is a risk of a collision. This call is a critical safety measure in aviation operations, ensuring that aircraft can separate to resolve potential conflicts in the airspace. The priority in aviation communications is always to maintain safety and prevent accidents, so in situations where two aircraft may be on a collision course, the breakaway is a necessary protocol to enhance separation quickly and effectively.

The other scenarios, while they may warrant communication with air traffic control or coordination, do not typically necessitate an immediate breakaway. Changing altitude, running low on fuel, or needing to switch maneuvers may involve discussions about flight plans or adjustments but do not inherently require an urgent separation maneuver aimed at avoiding collision. The ability to prioritize actions in emergency situations is crucial, highlighting why a breakaway is specifically linked to collision avoidance.
