Subchapter 10.5 – Common Readback Errors and Exam Traps

The Trap: ATC requests you "report leaving [altitude]" or "report level [altitude]." Some pilots forget to make these reports, leaving ATC uncertain of your altitude.

ATC: "OE-DMS, climb to flight level zero-eight-zero, report level." Later, you reach FL 080 and level off. Wrong: You don't say anything (thinking ATC will see you on radar). Correct: "OE-DMS, level flight level zero-eight-zero."

Rule: Always make the report ATC requests. "Report leaving" = call when you pass through. "Report level" = call when you level off.
