Mesa Airline Basic Indoctrination (BI) Practice Exam 2026 - Free BI Exam Questions and Study Guide

The idea being tested is how the Initial Operating Experience (IOE) is structured. IOE is the hands-on phase where a new pilot gains actual flight time in the airplane under supervision, bridging training and independent line operations. It ensures you’ve had real-world experience with the aircraft and airline procedures before you’re formally checked to fly the line on your own.

Because of that, the standard sequence is to accumulate a minimum amount of flight hours, then complete a competency check to verify you can operate the aircraft to the airline’s standards under normal and urgent circumstances. A competency check is the practical evaluation of your performance in flight, rather than a written or oral exam. The other options don’t fit this structure, since they either propose a different minimum hours or replace the practical competency assessment with another type of test. So, five hours of flight time, followed by a competency check, best matches how IOE is typically run.
