Purpose of Document

This purpose of this document is to provide guidelines for the development of pixelbased and especially touch-screen-based human machine interfaces (HMIs) for aircraft cabin system applications.

The numbers of functions available in the cabin of commercial aircraft have increased rapidly. Currently, these functions include elements such as the following:

• Control of the cabin lighting system

• Control of the cabin air-conditioning system

• Monitoring of the door, lavatory, and smoke detector status

• Operation of in-flight entertainment

• Operation of in-flight communication equipment (e.g., GSM, WiFi)

• Creation of cabin defect reports in digital form

Complex touch screen devices provide the HMI for control and indication elements necessary to handle these functions. Standardization of cabin system HMIs will provide consistency within the cabin and across the fleet of an airline, reducing the training burden for the cabin crew.

This standard may be applied to each HMI on each system's display or to an integrated display shared among systems (per ARINC Specification 628, Part 9, Attachment 3).

COMMENTARY

The images of graphical components of the HMI in this document should be regarded as examples and should not be used as design templates for actual HMIs. Instead, a set of graphical images representing the defined HMI components (see chapter 4) in all their various states should be created based on the guidelines in this document as a first step of HMI design.

Design examples in this document are based on a 1024x768 pixel display with a resolution of 72 pixels per inch (PPI).

This Standard is based on languages that are read left-to-right (LTR). For LTR languages, information is generally arranged from most important (upper-left) to least important (lower-right). For languages that are read right-to-left (RTL), the general arrangement would be roughly a mirror-image of the LTR arrangement. The guidelines for HMI (e.g., layout and symbols) will need to be adapted for RTL languages.
