What is the key factor considered in METT-TC when selecting a flight mode?

In the context of METT-TC, which stands for Mission, Enemy, Terrain, Troops, Time, and Civil considerations, the key factor when selecting a flight mode is the enemy presence. Understanding the enemy's capabilities and locations is crucial for operational planning, particularly in terrain flight operations where avoiding enemy detection and engagement is paramount.

When selecting a flight mode, the nature and disposition of enemy forces can dictate the need for stealthy, low-altitude approaches or other tactical maneuvers to minimize risk. This requires a clear assessment of how the enemy might respond, which flight paths are safer, and how best to utilize the aircraft's capabilities to achieve mission objectives without unnecessary exposure to adversarial actions.

While weather conditions, available resources, and time of day are certainly important considerations in flight operations, they do not hold the same level of priority in the initial decision-making process as the presence and potential actions of the enemy. This focus helps ensure that the chosen flight mode enhances mission success while maintaining crew and aircraft safety.
