What should Number 1 do after following a G-X maneuver?

After conducting a G-X maneuver, the appropriate action for Number 1 is to initiate a fuel and G check. This is crucial because the G-X maneuver is a high-performance maneuver that typically results in increased G-forces on the aircrew. The pilot needs to assess their own physiological state and verify fuel levels to ensure the continued safety and performance of the flight.

Initiating a fuel check ensures that the aircraft has enough fuel to complete the mission and return safely. Meanwhile, performing a G check involves verifying the tolerance to G-forces experienced during the maneuver, as sustained high G-forces can lead to physical effects such as G-induced Loss of Consciousness (GLOC). Understanding both fuel and physiological state is vital for the lead pilot to maintain situational awareness and make informed decisions moving forward in the mission.

The other options, while they may have their places in overall flight operations, do not specifically address the immediate needs following a G-X maneuver. For instance, while reviewing the flight plan and changing formation could be important, they do not prioritize the critical assessments of fuel status and the pilots' physical responses to G-loads that are essential after such maneuvers.
