About this practice suite
This suite prepares candidates for instrument comprehension selection in the aviation, aerospace, air traffic, and airports sector with 5 skill areas: spatial reasoning, attention and concentration, technical reasoning, numerical reasoning and critical thinking. Every question was written by Novus editors for this suite (none are taken from live or leaked exams), and the full bank holds 52 scored questions across three modes, plus 8 reserve questions used to vary repeat attempts. Answer keys never ship to the browser: your answers are scored server-side, and results stay on your device.
Skills this suite practises
- Spatial reasoning: Rotation, folding, views, orientation, maps, and three-dimensional visualization.
- Attention and concentration: Sustained focus, selective attention, and accuracy under time pressure.
- Technical reasoning: Applied technical principles, diagrams, tools, systems, measurements, and troubleshooting.
- Numerical reasoning: Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
- Critical thinking: Evaluating evidence, assumptions, arguments, credibility, and alternative explanations.
Sample questions from the guided bank
Two of the 10 guided-practice questions, shown exactly as they appear in a session. Answers and explanations are not printed here, because keys stay on the server. Open guided practice to answer them and see how you did.
The attitude indicator displays primarily:
- A. Passenger count
- B. Fuel flow only
- C. Outside air temperature
- D. Pitch and bank relative to the horizon
An altimeter set to the wrong subscale will show:
- A. Correct altitude always
- B. Incorrect altitude compared to true height
- C. Only airspeed errors
- D. Heading reversals
Practice modes and timing
Guided practice is untimed-feeling and instructional; the mini-test is a short timed check; the full simulation mirrors a complete sitting. All three draw on separate question sets, so moving up a mode never repeats what you practised.
| Mode | Questions | Duration | Start |
|---|---|---|---|
| Guided practice | 10 | 15 minutes | Open |
| Timed mini-test | 12 | 18 minutes | Open |
| Full simulation | 30 | 45 minutes | Open |
