Avionics aptitude

About this practice suite

This suite prepares candidates for avionics aptitude selection in the aviation, aerospace, air traffic, and airports sector with 5 skill areas: electrical reasoning, numerical reasoning, data interpretation, critical thinking and situational judgment. 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

• Electrical reasoning — Basic circuits, current, voltage, resistance, symbols, and electrical troubleshooting.
• Numerical reasoning — Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
• Data interpretation — Tables, charts, graphs, dashboards, trends, comparisons, and evidence-based conclusions.
• Critical thinking — Evaluating evidence, assumptions, arguments, credibility, and alternative explanations.
• Situational judgment — Evaluating workplace responses against role-relevant principles.

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. What does an open circuit mean in basic electrical troubleshooting?

   • A. Current path is interrupted and cannot flow continuously
   • B. Voltage is always zero everywhere
   • C. Resistance is exactly zero
   • D. The battery is fully charged

2. You must measure live avionics bus voltage. What is best?

   • A. Measure with power intentionally uncontrolled on bench
   • B. Use any metal screwdriver across terminals
   • C. Use approved meter, probe points, and ESD-safe procedures
   • D. Bypass circuit breakers to force reading

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.
