Applying for an ATC role at Heathrow?
Heathrow is one of the busiest airports in the world, handling over 70 million passengers and 470,000 aircraft movements per year. Air traffic controllers at Heathrow manage one of the most complex and high-pressure airspaces in global aviation — making the NATS selection process highly competitive.
NATS (National Air Traffic Services) provides ATC at Heathrow, and all trainee controllers must pass the Stage 1 online aptitude battery before progressing to the assessment centre. The tests cover spatial reasoning, numerical reasoning, logical reasoning and situational judgement — all of which are practised on this platform.
The Heathrow TMA (Terminal Manoeuvring Area) is one of the most demanding ATC environments in the world. Controllers must manage simultaneous approach streams on two parallel runways while coordinating with en-route sectors above. The situational judgement and logical reasoning elements of Stage 1 are specifically designed to identify candidates capable of performing under this level of pressure.
Our practice platform covers all four Stage 1 test types with 155 questions, timed simulations and detailed explanations. Each attempt uses a randomised selection of questions so every practice session is different.
