According to the remote pilot study guide, stress that presents an intolerable, ongoing burden exceeding a person's ability to cope, and that should prompt consulting a physician, is classified as which type of stress?

Why: The study guide defines chronic stress as "a level of stress that presents an intolerable burden, exceeds the ability of a person to cope," building up from an accumulation of smaller stressors, and recommends that pilots suffering from chronic stress consult a physician.

• Acute stress is the study guide's term for a short-term reaction to an immediate perceived threat that the body can typically cope with — the opposite of an ongoing, intolerable burden.
• Skill fatigue is a category of fatigue described elsewhere in the same chapter, not a category of stress.
