What is one prerequisite for air recon planning?

Air superiority is essential for effective air reconnaissance planning because it ensures that friendly forces can operate without the threat of enemy air defenses or hostile aircraft. When air superiority is achieved, reconnaissance missions can be conducted more safely and with greater operational effectiveness, allowing the collection of crucial intelligence without the risk of being engaged by adversarial air threats.

This condition enables the reconnaissance aircraft to maneuver freely and gather information without the constant need to evade enemy fire or deal with airborne threats. As a result, effective reconnaissance can provide critical data to inform command decisions and support ground operations, enhancing overall mission success.

In contrast, the other options do not represent prerequisites in the same way; fast aircraft and night vision may enhance reconnaissance capabilities, but they do not form the foundational requirement like air superiority does. Fixed-wing sensors are just one method of reconnaissance and not a blanket requirement, and therefore do not encompass the broader strategic necessity of having control over the airspace.
