What should be done if vertical speed mode is engaged without altitude armed?

When vertical speed mode is engaged without altitude armed, monitoring the pitch carefully is crucial because the aircraft will maintain its current vertical speed regardless of its altitude. This situation can potentially lead to altitude deviations that may not be corrected automatically, increasing the risk of unintentional altitude loss or gain.

By keeping a close watch on the pitch, the pilot can make necessary adjustments to maintain a safe and desired flight path. It allows for active management of the aircraft’s vertical profile, ensuring that the operation remains within safe parameters. Proper monitoring helps in decision-making about when to adjust the vertical speed or to arm the altitude if needed to ensure safe operation and compliance with flight plans or air traffic control instructions.

Adjusting throttle settings, engaging level-off conditions, or disengaging from vertical speed mode may not directly address the need for immediate awareness and control over the vertical speed aspect of flight, especially in a scenario where altitude awareness is critical.
