To demonstrate the consequences of a missed readback/hearback error, the aircraft must depart with which altitude clearance?

• A. 4,000 feet
• B. 14,000 feet
• C. 10,000 feet
• D. 8,000 feet

Answer: (B)

The situation tests how a missed readback/hearback can lead to an unsafe altitude deviation if the pilot departs with an altitude clearance without a proper, verified confirmation. Choosing a clearance for a higher altitude places the departure into a busy high-altitude environment where multiple aircraft commonly operate at the same level and where vertical separation relies on precise and verified assignments. A missed readback at this level is more likely to produce a meaningful demonstration of potential conflicts with other traffic, making the consequences clear. Lower-altitude clearances tend to involve different traffic patterns and fewer scenarios where a miscommunication would produce a noticeable risk, so they’re less effective for illustrating the issue.
