Two Pilots: How They Check Each Other

2 min read

The short answer

Every airliner is flown by two pilots who constantly check each other. One flies while the other monitors, every important action is called out and confirmed, and checklists are read aloud and answered. It's designed so that one person's slip is always caught by the other.

Two Sets of Eyes on Everything

Every airline flight has at least two fully qualified pilots. They're not just there in case one feels unwell. They're there to check each other, all the way through the flight.

One Flies, One Monitors

For each flight, one pilot is the pilot flying and the other is the pilot monitoring. The pilot flying controls the plane. The pilot monitoring watches the instruments, handles the radio and checks every move the pilot flying makes.

If anything looks different from what was planned, the pilot monitoring says so straight away. Both pilots are trained to welcome this — whoever spots something speaks up.

Calling Things Out

Pilots speak their actions aloud. "Gear down." "Flaps 20." "Checked." This simple habit means both pilots always know what's happening, and a wrong switch or setting is caught at once.

Checklists, Every Time

At each stage of the flight, one pilot reads a checklist item and the other checks it and answers. Even captains with thousands of flying hours use checklists on every single flight. It's not a lack of skill — it's how aviation makes sure nothing is ever missed.

A Quiet, Focused Cockpit

During take-off, landing and the busy parts of the flight, pilots keep the cockpit "sterile". That means no chatting about anything else — only what the flight needs. In the US this is a legal rule, applying to everything below 10,000 feet except cruise.

Teamwork Training

All of this is part of crew resource management — training in teamwork, communication and decision-making that pilots practise throughout their careers.

The Takeaway

Two trained pilots, checking each other at every step, with checklists and callouts — the cockpit is built so that no single slip goes unnoticed.
