Which of the following is/are procedurally correct when conducting a level speed change (LSC)?

Which of the following is/are procedurally correct when conducting a level speed change (LSC)?

• A. Start in normal cruise on any numbered heading; reduce power to -31%; trim for deceleration and stabilize at 150 KIAS
• B. When airspeed is below 150 KIAS, lower landing gear and flaps to desired setting
• C. After stabilized in no flap configuration, lower the flaps to landing, immediately adjust power to -52% and stabilize at 120 KIAS in land flap configuration
• D. Both A and C are correct

Answer: (D)

The option indicating that both A and C are correct highlights the procedures necessary for conducting a level speed change (LSC) effectively and safely. In the first part, starting in normal cruise on any numbered heading and reducing power to -31% is aligned with the procedure of initiating a speed reduction while maintaining control of the aircraft. Trimming for deceleration allows the pilot to stabilize the aircraft at a reduced airspeed of 150 KIAS, which is essential for maintaining altitude while descending in speed. In the third part of the option, after stabilizing at the no flap configuration, lowering the flaps to landing and adjusting power to -52% illustrates a continuation of the procedure where the pilot transitions to a configuration suitable for landing. Stabilizing at 120 KIAS in the landing flap configuration is crucial as it enables a controlled approach speed during landing, enhancing safety and precision. Combining these procedures from options A and C effectively illustrates the correct protocol for managing speed changes while ensuring stability and control throughout the process. Thus, both components contribute to a comprehensive understanding of how to execute a level speed change correctly.
