Linguistic scoring scheme for selection criteria.
| Linguistic scoring | TraFN | Selection criteria | Significance | Availability | Generalisability |
| Low | (0, 0.1, 0.4, 0.5) | The PI is insignificant and may not affect airport operation assessment if not included | The PI is hard to measure or data is hard to obtain | The application of PI is difficult in most of the airports |
| Medium | (0.25, 0.35, 0.65, 0.75) | PI is significant and may improve airport operation assessment | PI can be measured or data is easily accessible | The application of PI asks for certain requirements of the airport, but still applicable |
| High | (0.5, 0.6, 0.9, 1) | PI is highly significant; the overall benefit assessment may not be reliable if not included | PI can be easily measured, and the data is easy to obtain | PI can be easily applied in most of the airports |
