Airplane Vibration and Flight Crew Response

摘要

Modern commercial jet airplanes provide smooth, comfortable travel that typically is free of vibration. Some types of vibration can be expected from time to time and are considered normal. However, isolated cases of abnormal vibration require prompt flight crew response and subsequent timely maintenance action. Occasional airplane vibration during flight is not unusual. There are many causes of airplane vibration, including landing gear extension and retraction, extension of speed brakes, free play in movable surfaces, and systems malfunctions. Flight crews need to understand the causes and effects of airplane vibration so they can take appropriate action to maintain flight safety and prevent excessive wear or airframe damage. In addition, flight crews can contribute to accurate reports of in-service events that will facilitate troubleshooting and maintenance activities. Understanding the possible sources of vibration and the information needed to isolate and correct vibration problems requires knowledge of the following: 1. Types of vibration and noise; 2. Causes of airplane vibration; 3. Detection of airplane vibration; 4. Flight crew response; and, 5. Maintenance troubleshooting.
