Can you pass the ATSA cold?
The ATSA is difficult because its tasks are unlike most everyday activities. Take this short challenge to preview four sections and see how you respond to the format.
This is a simplified trial version and does not accurately reproduce the actual ATSA. It is designed to give you a basic understanding of the test format and what to expect.

Can you keep up?
You will see one continuous sequence of single-digit numbers. Remember the first number. When the next number appears, enter the absolute difference between it and the previous number before time runs out. After each answer, continue remembering the number currently displayed because it becomes the previous number for the next question. Repeat this process until all six scored attempts are complete.
"Focus only on the last number you saw — nothing else. The moment a new number appears, start calculating. Don't wait for it to disappear before your brain kicks in."
Memory complete.
Whose left is it?
An aircraft and a red ball appear on screen. Is the red ball on the aircraft's LEFT side or RIGHT side? Each question tells you which perspective to use.
Aircraft perspective: imagine a line through the center of the aircraft from the tail to the nose. The aircraft's left is the side to the left of that line as it flies forward, and its right is the other side. In this trial the aircraft flies toward the right of the screen, so its left is the top of the screen and its right is the bottom.
Tower perspective: picture yourself in the control tower at the bottom of the screen, looking up at the aircraft. LEFT and RIGHT are what you see from there — if the ball appears on the left side of the aircraft, answer LEFT. The direction the nose points does not matter.
"The #1 mistake is answering from your own perspective instead of the one the question specifies. Pause, mentally step into that cockpit or tower, then answer. That single habit is worth 10 correct answers."
Spatial complete.
50 seconds on radar.
Numbered targets enter, cross, and leave the radar area in short waves. Click one aircraft when two paths create a collision risk — while answering basic math questions at the same time. 50 seconds. Collision prevention comes first.
Watch the colors: orange means a collision is imminent, and red means the targets have collided. These color warnings are for practice purposes only. You can remove a target by clicking it or by typing its number on the keyboard. You can answer math questions by clicking an answer or by pressing A, S, D or F.
"Collision prevention first — always. Scan for aircraft converging toward each other before you glance at the math. A math question can wait 3 seconds. A collision cannot."
Simulation complete.
What kind of controller are you?
No right or wrong answers. The ATSA includes a behavioral section, and this preview shows how it works and gives you a chance to reflect on your work style. After each block, you'll see which trait your choice points to.
"Answer based on how you actually behave at work — not how you wish you did. There are no trick answers."
👤 Behavioral complete.
You chose your Most and Least statements across all four blocks. This section isn't scored — the traits you chose will appear with your results.
