United Services Automobile Association (USAA) Oral Practice Test

The main idea here is that weather can change after a flight plan is amended, so you must recheck weather information when a plan is adjusted for a ground delay. A new departure time means the forecast for winds aloft, temperature, icing, turbulence, and convective activity can be different, which can affect fuel needs, routing, and potential alternates. By reviewing updated weather data—METARs, TAFs, SIGMETs/AIRMETs, radar, and weather charts—you can confirm that the chosen route and alternate airports remain safe and feasible within your fuel reserves, and you can adjust the plan if necessary. Passenger lists, maintenance issues, and airport fees aren’t directly involved in whether the amended flight plan remains viable from a weather and safety standpoint, so they don’t carry the same impact on the plan’s feasibility as updated weather information does.
