What are the vision requirements for a Class I medical certificate?

For a Class I medical certificate, the vision requirements ensure that pilots possess adequate visual acuity to safely operate an aircraft. The specific standard for distant vision is a correction of 20/20 or better, which demonstrates that a pilot can see at 20 feet what a person with normal vision can see at the same distance. Near vision is required to be 20/40 or better, allowing pilots to read instruments and other important materials in the cockpit effectively.

Meeting these standards is critical for safety in aviation, as pilots must be able to detect and respond to visual cues from the environment, such as other aircraft, navigation aids, and potentially hazardous situations. The established criteria aim to prevent visual deficiencies that could impair safe flight operations.

Therefore, the correct answer reflects the vision requirements accurately, confirming the importance placed on visual acuity in the aviation medical certification process.
