Is carrying checklist mandatory for pilots?

Carrying a checklist is not legally mandatory for pilots, but it is highly recommended and considered best practice. Checklists enhance safety by ensuring that critical pre-flight, in-flight, and post-flight procedures are followed systematically. Many aviation authorities and airlines require their pilots to use checklists to comply with safety regulations and standard operating procedures. Ultimately, using a checklist helps reduce the risk of errors and improves overall flight safety.
