In which type of descent does an aircraft lose altitude at a controlled rate?

1. Emergency Descent

2. Minimum Safe Airspeed Descent

3. Partial Power Descent

4. Free Descent

The correct answer is: Partial Power Descent

The type of descent in which an aircraft loses altitude at a controlled rate is known as Partial Power Descent. This method allows the pilot to maintain a certain level of thrust while descending, which enables effective management of airspeed and descent rate. The controlled descent can be beneficial in situations where conserving altitude or optimizing fuel efficiency is necessary. In this type of descent, pilots manage the power settings and trim to create a balance that allows for a steady and controlled rate of descent, thereby enhancing safety and operational efficiency. The technique often proves useful during approaches and landing preparations, where precise control over altitude is paramount. Other types of descents listed typically involve less control or changes in technique that might not provide the same stability. Emergency descents are characterized by rapid altitude loss for urgent circumstances, minimum safe airspeed descents focus on maintaining the lowest but safe speed, and free descents are usually uncontrolled and based solely on gravity without power management, which is the opposite of what is achieved in Partial Power Descent.
