Judgement, Decision-Making, and Intuition in the Pilot Selection Process

Could there be a time when best options are frustrated by an abundance of system messages that complicate or confuse the pilot decision process? When Airbus emerged in the aircraft manufacturing market in the 1970s and 1980s, one of their aims was to increase automation of systems. Their aircraft had to be suitable for pilots with an abundance of flight experience and for pilots with limited experience. Safety through automation has paid off over the years for Airbus. Flight envelope protection allows pilots to operate the aircraft as normal, but they are restricted by the aircraft from operating outside performance limits (Airbus, 2018). Commonality of design and handling allows pilots to easily add type ratings across the entire fleet of Airbus aircraft. This reduces training costs dramatically (Airbus, 2018). However, just how restrictive are the systems on an Airbus aircraft? Do these systems interfere with pilot decisions? The following engine failure report will highlight some of the decision-making challenges facing Airbus pilots.
Inanimate Debris Generated by Adverse Weather Conditions

Flight test must be made on an airplane during a severe rainstorm. Aircraft should be equipped with measuring devices to record the environmental parameters to explore the safe flight envelope of the aircraft [146]. However, many difficulties arise in these cases including the hazard to the test pilot, the difficulties for extracting accurate performance measurements and environmental parameters, and the extreme difficulty (if not impossible) to obtain the same characteristics of natural rain in several test.

The EFCS controls the movements of stabilizers, spoilers and rudder providing pitch, roll and yaw damping and trim capability. It assures adequate responses throughout the flight envelope. Secondary flight controls are flaps and slats while the spoilers are also used as airbrakes and lift dumpers.

We expected the haptic feedback to have an influence on performance, safety, workload, and pilot situation awareness. Performance was defined as the altitude lost during the windshear recovery, where less is better, or the deviation from the indented flight path during the instrument approach. Pilots were considered to be safe when margin was kept from the flight envelope limits, this was measured by the absolute distance from the aircraft state to the limit, the time pilots flew close to the limit, and the integral of the state above the flight envelope protection limit. The latter is a combination of both time and distance over the limit. Workload was measured using a Rating Scale Mental Effort (RSME) (Zijlstra, 1993), whereas subjective situation awareness was measured by asking the pilot whether (s)he was in control, and whether (s)he was missing information, ideally, a pilot is in full control and misses no information. For the experiment, it was hypothesized that the haptic feedback system supports pilots in their manual flying task, and therefore improve performance, increase safety, reduce workload, and improve situation awareness. Furthermore, we provided pilots with a debriefing questionnaire of 20 questions to query their experience with the haptic feedback and simulation environment. Statistical analysis was performed using a Wilcoxon test for questionnaires, ANOVA for ratio data, with a significance level of .
