Abstract : This Report follows Technical Notes IAP 1132 and 1138, which dealt with the location and form of visual information in the Head-Up Display, and concludes the basic work on the presentation of steering information during visual flight. It is concerned with the influence of errors and limitations arising both in generating and in presenting the visible form of the display. When a display is generated by electronic means errors of form and noise effects may occur. Form errors do not affect performance as long as the user is able to identify and interpret significant configurations of components of display form, whilst gross deformations are acceptable under specific conditions. Effects of noise in a fixated field are negligible unless manifest differentially in components of the field. The means used to present the display may limit the information capacity of the system and may give rise to misalignment effects. Adequate capacity is available for instrument flight information but the form of display is to some extent prescribed. Misalignment is tolerable under certain circumstances. (Author)
