🔍 Key Concepts

• Carefully match each numbered label in the illustration to the physical shape and function of that part. • An air door handle will normally look like a small lever or hand-operated piece used to open/close an air door or vent. • Focus on the right-hand circular cover view and identify which number is attached directly to a handle-like shape on the air door.

💭 Think About

• On the right-hand view, which numbered item clearly looks like a handle that a person would grip and move by hand? • Which of the answer choices is pointing to a part that is directly mounted on, or very close to, the air door itself rather than on remote linkage or cylinders? • Compare the shapes for 4, 6, 7, and 12: which one most resembles a simple lever/handle rather than a valve body, actuator, or linkage assembly?

✅ Before You Answer

• Verify which numbered item is actually on the door face in the right-hand illustration, not part of the external mechanism on the left. • Confirm that the chosen number’s arrow points to a hand-operable lever shape, not a wheel, cylinder, or complex housing. • Ensure your choice is limited to the four options given (4, 6, 7, 12) and that only one of them is a clear handle fixed to the air door.
