Case study respondents reported that they have less func- tionality with a common use implementation than they do with their proprietary system. For example, the functionality of one respondent's gate information display system (GIDS) is not available through common use installations. This sys- tem enables the gate agents to display the status of their stand-by list for the current flight, among other features. For GIDS to be present in a common use environment, the airport operator must provide a second computer or space for a second computer to drive the data to the gate display. Most airports object to adding the airline-specific computer, be- FIGURE 6 Airport on-gate parking. cause this changes the gates to a more dedicated format, thus somewhat diminishing the airport's ability to use the gate as and require at least one certification process by the vendor a common use gate. before being released.
