HMI Trainer

International recruits arrive fluent in their own system, then get handed a three-hundred-and-fifty-page document that reads like a software test script. Left-click this, you'll see that, select that. After a day or two they report feeling like frauds — unable to use the system while trying to demonstrate the skills they've relied on their whole career at another ANSP.

The HMI Trainer is a twenty-hour program that replaces the manual with structured fluency building. It teaches no more than five new concepts per module, in shuffled order so you're never repeating the same sequence. You need streaks of four correct to pass a module and five in a row to be deemed fluent, then you sit a timed test with no reference access.

Complexity comes in three layers — shallow, medium, and deep. Shallow is the most direct path, like left-clicking the CFL to open a dropdown and select a level. Medium adds qualifiers, such as assigning a block level or flying visual. Deep is the system's weird corners, like typing a custom flight level that isn't on the dropdown by opening the flight plan instead. You complete all thirty components at shallow, sit a test, then medium, then deep, then a final five-minute completion test where every option can come up and pills are gone — pure recall.

At each level the pills update to give more depth and reference material aligned to that complexity. They support you while you learn, then disappear for the final exam.

On day one of conversion, recruits are validating things they've already learned rather than throwing up objections to how the new system does things. They stop feeling like imposters and start sounding like the controllers they already are.
