What is a Level Bust?
A Level Bust is defined as: A deviation of 300 feet or more from the assigned level This may take one of three different forms: 1. An aircraft in level flight climbs or descends without clearance 2. An aircraft climbing or descending fails to level off accurately at the correct level (either passing through and continuing the climb or descent, or passing through and then returning to the correct level) 3. An aircraft levelling off at the correct level or altitude, but with an incorrect altimeter setting Click the graphic below to see a flash animation of Examples 1 & 2.
