Final answer:

It is true that different checklists exist for early and late model Cessna 172s due to updates in procedures and equipment through the years, which impacts the operational steps needed for safety.

Explanation:

The statement about whether there are different checklists for early and late model 172s is True. In the aviation industry, particularly when dealing with aircraft like the Cessna 172, checklists can vary depending on the model and year of the aircraft. Manufacturers often update procedures and equipment through the model years, necessitating different operational steps that must be reflected in the pre-flight, takeoff, cruising, and landing checklists.

The early models of any aircraft might have different operating procedures, limitations, or equipment compared to the late models, hence it's critical for pilots to adhere to the checklist specific to their aircraft's model to ensure safety and compliance with aviation regulations.
