What phase of flight does 'POPCORN' signify?

'POPCORN' refers to a specific moment during flight associated with initiating a climb for air-to-surface (A/S) attack. This terminology is used to describe the transition from a stable flight position to an aggressive upward maneuver aimed at gaining altitude efficiently for targeting purposes. In such a scenario, the pilot is typically preparing to execute an attack on a ground target, ensuring proper altitude and positioning for an effective strike.

Understanding the implications of this phase is critical, as it involves considerations related to aircraft performance, energy management, and target engagement tactics. The ascent brought about by 'POPCORN' is not only a physical action but also a tactical development that reflects on the aircrew’s overall strategy during combat situations.
