What indicates that a position change has been directed by lead?

The correct indication that a position change has been directed by lead is found in the phrase "PAIN Flight, position change." This command is clear and concise, signaling to all parties involved that a change in positioning is required. The term "position change" specifically indicates the action needed, and by using this language, it ensures all members of the flight are on the same page about the necessary adjustments.

Other phrases might suggest a need to change position but may not communicate the order as effectively. Phrases that use "change position now" or "move to new position" could imply urgency or suggest alternative actions rather than providing a clear directive. In a flight context, clarity and brevity in communication are vital to ensure safety and effective coordination among team members.
