Which percent range of power should be set before lowering the landing gear at DEGA?

Setting the power to the 4-6% range is appropriate before lowering the landing gear during the DEGA (Descent, Engine, Gear, and Approach) phase. This specific power setting ensures that the aircraft maintains a stable descent rate and an appropriate airspeed while deploying the landing gear. Lowering the gear at this power setting allows the pilot to effectively manage the changes in drag and lift that occur as the gear is extended, helping to avoid excessive descent rates or airspeed fluctuations that could affect the aircraft's handling qualities.

In this phase of flight, it is critical to maintain a careful balance between power, airspeed, and descent rate. Setting the power at 4-6% not only provides a margin for a controlled descent but also aligns with the T-6B's operational procedures for optimal aircraft performance. The focus is on maintaining stability and preparing for a smooth transition to a landing approach as the pilot prepares for final approach and landing.
