Preface

Controllers are required to issue an altimeter setting to enroute aircraft:

1.

1. Upon initial contact

2.

2. Every thirty minutes

3.

3. At least once during your time in their airspace

4.

4. As a not-so-subtle hint to get back on your assigned alti-tude so a bust can be avoided

If you enjoyed taking this interactive quiz and would like to see more like it, go to the IFR Quiz page. And if you thought it was unfair, confusing, or a waste of time, we'd like you to tell us that, too. And if you have an idea for a subject that you think would make a good future IFR Quiz, be sure to let us know.
