When flying partial panel due to gyroscopic instrument failure, which instrument should be prioritized for climbs and descents?

In a partial panel scenario where there is a gyroscopic instrument failure, the airspeed indicator should be prioritized for climbs and descents. The airspeed indicator is crucial because it provides essential information on how fast the aircraft is moving through the air, which is vital for maintaining safe flight. During climbs and descents, being aware of the airspeed ensures that the aircraft does not stall or exceed its operational limits.

While the vertical speed indicator provides important information about the rate of climb or descent, the airspeed indicator is more critical in this situation because it helps the pilot manage the aircraft's performance and avoid potentially dangerous flight conditions. The attitude indicator, while useful for understanding the aircraft's orientation, is not functional in a partial panel scenario with gyroscopic failure, and the heading indicator does not directly contribute to safe climb and descent management. Thus, focusing on the airspeed indicator allows for better control and safety during these phases of flight.
