What bank angle should be established during the initial part of a Chandelle?

1. 10 degrees

2. 25 degrees

3. 30 degrees

4. 45 degrees

The correct answer is: 30 degrees

During the initial part of a Chandelle, a bank angle of 30 degrees is generally established. This bank angle is crucial because it strikes a balance between maintaining a sufficient rate of turn while also allowing for the necessary change in altitude and airspeed. In a Chandelle, pilots aim to achieve the maximum lift-to-drag ratio and utilize the power of the aircraft effectively. The 30-degree bank provides optimal performance, creating a coordinated turn that helps maintain control throughout the maneuver. It enables the aircraft to execute the turn without excessive load factor that could lead to potential stall or undesirable aircraft performance. Furthermore, this bank angle supports a smooth transition from the horizontal flight configuration into an ascent, ensuring that as the aircraft climbs, it maintains the appropriate airspeed for the maneuver. In summary, establishing a bank angle of 30 degrees allows for a controlled, efficient, and clean performance of the Chandelle, catering to both safety and performance standards in flight.
