What code should VFR aircraft conducting Search and Rescue (SAR) missions squawk?

For VFR aircraft conducting Search and Rescue (SAR) missions, the appropriate transponder code to squawk is 1277. This code is specifically designated for search and rescue operations and is recognized by air traffic control and other aircraft for these missions. By using this code, the aircraft can communicate its purpose effectively, and it helps ensure that they are given the attention and support needed during a SAR operation.

In the context of aviation protocols, it's crucial for VFR aircraft engaged in these missions to be easily identifiable to both other aircraft and air traffic control to facilitate safety and coordination in potentially challenging airspace environments. Other codes, while relevant to different operations, do not specifically relate to SAR activities.
