The pilot's safety problem in category 2 operations and the potential contribution of head-up display. Initial investigation of head-up display at B.L.E.U

Abstract

This paper aims to fulfil two main functions; firstly, it highlights what is believed to be the main safety problem in current bad weather landing and secondly, it presents results of initial flight trials with a head-up display which show that this aid has great potential value for Category II operations. The safety problem is shown to lie in the limitations of the pilot in controlling the aircraft in pitch, using visual guidance. The head-up display is recommended as a solution to this problem as it can provide an efficient means of combining instrument and visual information. In addition, further improvements could be achieved by optimisation of cockpit procedures, whether or not a head-up display is adopted.
