What is the minimum amount of dual time required for a PPL applicant?

The minimum amount of dual time required for a Private Pilot License (PPL) applicant is indeed 20 hours. This requirement is established by the FAA regulations, which specify that an applicant must have at least 20 hours of flight training with an instructor. This training is crucial as it covers essential areas like flight maneuvers, navigation, and emergency procedures, ensuring that the student pilot develops the necessary skills and knowledge to operate an aircraft safely and competently.

This dual instruction is a foundational component of flight training, as it allows for tailored teaching and direct feedback from the instructor, which enhances the learning process and helps to build a solid foundation for the student. The other options listed do not meet the regulatory minimum requirements set by the FAA and therefore, are not appropriate answers in this context.
