Kurzfassung

Introduction: A new noise-reduced landing approach was tested – a Segmented Continuous Descent Approach (SCDA) - with regard to the resulting workload on pilots. Methods: Workload of 40 pilots was measured using physiological (heart rate, blood pressure, blink frequency, saliva cortisol concentration) and psychological (fatigue, sleepiness, tension and task load) parameters. Approaches were conducted in A320 and A330 full-flight simulators during night shift. SCDA was compared to the standard Low Drag Low Power (LDLP) procedure as reference. Results: Mean heart rate and blood pressure during the SCDA were not elevated, partly even significantly reduced (on average by 5 bpm and 4 mmHg regarding the flying Captain). Cortisol levels did not change significantly with mean values of 0.9 to 1.2 ng/ml. Landing was the most demanding segment of both approaches as indicated by significant increases in heart rate and decreases in blink frequency. Subjective task load was low. Discussion: Both approach procedures caused a similar workload level. Interpreting the results, methodological limitations have to be considered, e.g. the artificial and controlled airspace situation in the flight simulator. Nevertheless, it can be concluded that under these ideal conditions, the SCDA is operable without a higher workload for pilots compared to the common LDLP.
