What is the correct procedure to perform a zoom maneuver?

The correct procedure for executing a zoom maneuver involves pulling up to a 20-degree nose-high (NH) climb while maintaining an airspeed of 150 knots indicated airspeed (KIAS) or higher. This technique is designed to maximize the aircraft's altitude gain in a short amount of time.

By initiating a climb at this specified angle and speed, the pilot effectively converts the aircraft's kinetic energy (speed) into potential energy (altitude). This maneuver is particularly useful when maneuvering to gain an advantage during combat or in tactical scenarios, allowing the aircraft to reach a higher altitude for greater operational effectiveness. Maintaining the appropriate speed ensures that the aircraft remains within the performance envelope, preventing stalling and ensuring a smooth transition to climbing flight.

The other choices do not accurately represent the correct zoom maneuver procedure. For instance, maintaining level flight while increasing airspeed does not achieve the objective of altitude gain and is not part of the zoom maneuver's intent. Rapid descents directly conflict with the purpose of the maneuver, as it aims to climb rather than descend. Lastly, performing a 3G pull-up without the context of speed does not align with the structured approach needed for a proper zoom maneuver, as the maneuver requires specific parameters for optimal execution.
