Plain English Meaning
Airsickness that is just starting. The learner isn't fully sick yet, but the first warning signs are showing up.
Full Definition
The earliest stage of airsickness, when a learner begins to show or feel the first signs of motion-induced illness — such as paleness, sweating, yawning, swallowing, or mild nausea — before full symptoms develop.
Context Anchor
Seen in flight training when an instructor is watching for early signs that a learner is becoming physically uncomfortable in the aircraft.
Derivation
From Latin 'incipere', meaning 'to begin'. 'Incipient' describes something that is just starting or in its earliest stage. So 'incipient airsickness' literally means airsickness that is beginning to appear.
Why Pilots Care
Instructors must spot these early signs in learners to take action before discomfort interferes with training effectiveness or safety.
Grounding Statement
A learner who becomes quiet, pale, sweaty, or uneasy during maneuvers may be showing incipient airsickness before saying anything is wrong.
