The correct choice identifies the parade altitude checkpoint as when the lead's inboard exhaust stack is fully visible and touches the bottom wing. This checkpoint is significant because it establishes a consistent reference for maintaining proper formation flight and altitude. In disciplined formations, pilots rely on visual cues to ensure that they are positioned correctly in relation to one another, especially during maneuvers like parade formations that require precision.

When the inboard exhaust stack aligns with the bottom wing, it typically indicates that pilots are at the appropriate altitude within the formation, preventing excessive spacing or altitude discrepancies that could lead to unsafe flying conditions. This visual reference helps maintain the integrity of the group’s flight path and cohesion.

In contrast, while the other options might involve visual references during flight, they do not serve as standard indicators for parade altitude. For instance, seeing the lead's left wingtip or tail light could be useful for general orientation or awareness, but they do not specifically relate to achieving the correct altitude formation. Similarly, the visibility of the landing gear doesn't provide relevant information about altitude in the context of a parade formation.
