Instrument comprehension

About this practice suite

This suite prepares candidates for instrument comprehension selection in the aviation, aerospace, air traffic, and airports sector with 4 skill areas: spatial reasoning, attention and concentration, 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.
• 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 — keys stay on the server — so open guided practice to answer them and see how you did.

1. The attitude indicator displays primarily:

   • A. Passenger count
   • B. Fuel flow only
   • C. Outside air temperature
   • D. Pitch and bank relative to the horizon

2. 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.
