Cockpit Switching Study: Test and Validation of a Design Procedure for Multifunction Switching Controls.
Abstract
The document reports the test and validation of a 'handbook' design procedure, developed during an earlier study, for the step-by-step design of multifunction switching controls (MSC's). An MSC panel for the Navigation and Weapons Delivery System of the A-7E airplane was designed using the procedure, and this panel was then analytically compared with conventional controls on the basis of pilot workload. Variations of the baseline MSC were also designed and tested to ascertain the effect of imposing constraints on the design procedure. The workload comparison was accomplished using a digital computer program developed specifically for workload evaluation. Results show the MSC panels in all respects at least equal, and in most cases superior, to conventional controls on the basis of pilot workload. In addition to the workload advantage, the baseline MSC panel occupied only one-tenth the panel space required for equivalent conventional controls. (Modified author abstract)
