Aircraft automation, particularly the automation surrounding vertical navigation, has been cited as an area of training difficulty and a source of confusion during operation. A number of incidents and accidents have been attributed to a lack of crew understanding of the automation. This paper describes an experiment which evaluated the training effectiveness of a new display for automated vertical flight guidance. The study investigated the extension of a formal methodology used to design the vertical guidance logic in the latest generation of autoflight systems. The experiment utilized a training package to teach the vertical guidance portion of the Flight Mode Annunciator (FMA) display, as seen in normal automated operations of the MD-11. The training package was administered to two groups of participants, with one group receiving the current MD-11 display, referred to as the Control-Based FMA, and the other group receiving the new display, referred to as the Guidance-Based FMA. The results showed that participants using the Guidance-Based FMA performed significantly better on some metrics.
