When should you accomplish items in the after landing checklist?

The after landing checklist should be accomplished once you are clear of the runway and at a safe taxi speed because this timing allows for safe operation of the aircraft while ensuring that attention can be devoted to both maintaining control during taxi and completing the checklist items. Performing the checklist while still on the runway or immediately after touchdown can distract from the critical task of ensuring safe exit and maneuvering on the runway. Additionally, doing it before reaching the runway threshold may not provide enough context for the pilot to accurately complete the checklist steps, which are based on the status of the aircraft and its environment upon exit from the active runway. This approach prioritizes safety and effective management of the aircraft during the critical phases of landing and taxiing.
