Controls, Tell-tale and Indicators: Focus on common space regarding the current regulation
Presentation concerning the asynchronous use of an indicator space for communicating information to the driver. The presentation explains the concept of this “common space” that two or more symbols may share but only use one at a time. The presentation proposes that two or more symbols might be displayed sequentially in the same common space (i.e., alternately flashing symbols).

Proposal for Supplement 9 to Regulation No. 121 (OICA)
Proposal for Supplement 9 to Regulation No. 121
Proposal to adapt the provisions for multi-function displays to technological progress. In principle, current displays can convey more information to the driver, including levels of severity or importance, while the current text was written when technologies were less flexible. As a result, the current provisions risk impeding the use of beneficial multi-function tell-tales. This text is based on informal document GRSG-105-21.
