What is the standard expectation when you receive a clearance with an altitude assignment?

• A. Propose a change to the altitude if you think it’s unsafe.
• B. Read back the altitude exactly and confirm reception; proceed as directed.
• C. Question ATC if you suspect an error before proceeding.
• D. Immediately begin a descent without confirmation.

Answer: (B)

When you’re given an altitude clearance, the essential step is to read back the exact altitude and confirm you received it. This creates a clear, auditable check that you heard the instruction correctly and that ATC has the same target you do, which helps prevent miscommunications that could lead to an unsafe altitude deviation. After you’ve confirmed with a precise readback, you proceed as cleared unless you need to request a change or clarification through proper ATC channels. If the assigned altitude seems unsafe or conflicts with your flight plan, you shouldn’t change it on your own; instead, ask ATC for clarification or a different altitude using standard phraseology. Descending or climbing without confirmation is unsafe and not how clearance procedures are supposed to be followed. If you suspect an error, you can seek clarification with ATC, but the required action remains to read back the altitude exactly and confirm reception before proceeding.
