During a single-engine approach, what should pilots primarily monitor?

During a single-engine approach, pilots should primarily focus on airspeed and configuration. Maintaining the correct airspeed is crucial because it ensures that the aircraft remains within safe operational limits and can adequately perform the necessary maneuvers while maintaining control. If the airspeed is too low, there's a risk of stalling, especially in a single-engine configuration where the loss of thrust from one engine can dramatically affect performance.

Configuration refers to the aircraft's settings regarding flaps, gear, and any other relevant systems that influence aerodynamic performance. Proper configuration helps optimize lift and drag, ensuring the aircraft can fly safely and efficiently during the approach phase. Monitoring these parameters allows pilots to ensure they can maintain control and make necessary adjustments should the situation change, such as needing to go around or landing.

While other factors like flight altitude and heading, engine temperature and pressure, and fuel level are important for overall flight safety and operation, they do not require the same level of immediate attention during a single-engine approach as airspeed and configuration do. This focus is essential because it directly relates to controlling the aircraft and ensuring a safe landing.
