Spatial Reasoning for ATC: Tips to Improve Your Score

2 May 2025·6 min read

Spatial reasoning is one of the most tested skills in the NATS Stage 1 battery. Here's how to understand it, practise it, and improve quickly.

Spatial reasoning is consistently one of the most challenging elements of the NATS Stage 1 aptitude battery for candidates with no aviation background. The good news: with targeted practice, it is also one of the fastest areas to improve.

What Is Spatial Reasoning in the ATC Context?

In ATC selection, spatial reasoning tests your ability to:

**Understand compass bearings and headings** — knowing that 045° is North-East, that a right turn increases the heading number, and that reciprocal headings differ by 180°

**Track aircraft positions** — given a starting position and a sequence of movements, identifying where an aircraft ends up

**Calculate turns** — if an aircraft is on heading 270° and turns right 90°, it is now on 360°

**Interpret radar-style plan views** — understanding which direction an aircraft is moving on a North-up display

Key Concepts to Master

Compass Bearings

Learn the main compass points and their degree equivalents:

North = 000° (or 360°)

East = 090°

South = 180°

West = 270°

North-East = 045°, South-East = 135°, South-West = 225°, North-West = 315°

Turning Rules

**Left turns decrease the heading number** (e.g., 180° → 090° is a 90° left turn)

**Right turns increase the heading number** (e.g., 090° → 180° is a 90° right turn)

When a heading passes through 360°/000°, wrap around (e.g., 350° + 30° right = 020°)

Runway Designations

Runways are numbered by dividing the heading by 10 and rounding. Runway 09 = ~090°, Runway 27 = ~270°. Runways 09 and 27 are opposite ends of the same strip.

Clock Position

Traffic described as "3 o'clock" is to your right. "9 o'clock" is to your left. "12 o'clock" is straight ahead. "6 o'clock" is directly behind.

Improvement Strategies

**Practice compass calculations daily.** Set yourself 10 bearing problems a day — it takes 5 minutes and produces noticeable improvement within a week.

**Draw diagrams.** When practising, sketch the aircraft position, draw the turns, and check your answer visually before selecting it. Over time you'll do this mentally.

**Learn the reciprocal trick.** Add or subtract 180° to find the opposite bearing: the reciprocal of 045° is 225°, of 270° is 090°.

**Use ATC Practice's Spatial Reasoning module.** 40 ATC-themed spatial questions covering all the formats used in NATS Stage 1, with detailed explanations showing the calculation method.

Realistic Expectations

Most candidates see measurable improvement in spatial reasoning after 10–15 hours of focused practice. The key is to practise with explanations — not just checking whether you got the answer right, but understanding exactly why.
