55 Appendix A presents the data obtained from the NLDN and used to produce a synthetic lightning duration scenario for the two case study airportsâChicago-OâHare International (ORD) and Orlando International (MCO), as described more fully in Chapter 3. The data depict the start and end times of lightning events during a full-year period based on the â30/30â rule (Table A-1 and Table A-2), and for the summer months when considering a â30/15â adaptation (Table A-3 and Table A-4). These data were then evaluated to generate per-minute cost savings that can potentially be achieved by reducing the time interval between stopping and resuming aircraft ramp activities.
