FAA Private Pilot Helicopter (PRH)Human FactorsHard
During a rapid descent in a pressurized environment, a pilot experiences sharp ear pain and cannot equalize pressure in the middle ear through normal swallowing. What technique should the pilot use to relieve this discomfort?
- AYawn repeatedly with the mouth wide open until pressure equalizes on its own
- BHold the breath and bear down forcefully as during weightlifting
- CPerform a Valsalva maneuver by gently pinching the nose and blowing while keeping the mouth closed
- DImmediately climb back to cruising altitude and descend more slowly next time
Show answer & explanationAnswer & explanation
Correct answer: C. Perform a Valsalva maneuver by gently pinching the nose and blowing while keeping the mouth closed
The Valsalva maneuver—gently pinching the nose and blowing against a closed mouth and nose—forces air up the Eustachian tube to equalize pressure between the middle ear and the environment, relieving the pain of a blocked ear during descent.
Why the other options are wrong
- A. Yawning can help mild pressure changes but is often insufficient for a painful, blocked ear during rapid descent.
- B. Bearing down forcefully like weightlifting (a true Valsalva against a closed glottis) does not equalize ear pressure and can cause other physiological issues.
- D. Climbing back is a valid emergency option but not the primary technique used first for a normal ear block.
Valsalva Maneuver (Ear Block Relief)
A technique of gently pinching the nose and blowing with the mouth closed to force air through the Eustachian tube and equalize middle ear pressure during descent.
- Used to relieve middle ear block during descent
- Should be done gently to avoid inner ear damage
- A cold or sinus congestion can prevent proper equalization, requiring the pilot not to fly
Memory trick: 'Pinch, blow, pop' — clear the tube like popping ears on a plane.
