A **waypoint** is a fixed reference point used in air navigation.

Instead of flying with only one start and end point, aircraft often move from waypoint to waypoint along the route.

## 📍 1. A Waypoint Is a Position in Space

A waypoint is a known location defined in navigation systems.

It may not be visible from the window, but for the aircraft it is a real navigation reference.

Waypoints help organize where the airplane should go next.

## 🧭 2. Routes Are Built From Many Waypoints

A flight route usually includes a sequence of waypoints.

That sequence helps guide the aircraft:

- after departure
- during cruise
- during arrival

👉 They act like markers along an invisible sky route.

## 📡 3. Modern Systems Use Them Constantly

Navigation computers and flight plans rely heavily on waypoints.

Crews use them to:

- monitor route progress
- manage turns
- connect procedures together

Waypoints are a basic part of modern air navigation.

## ✨ What It Means

Waypoints make long, complex routes manageable.

They break a journey into precise navigation points that aircraft can follow with accuracy.

## 💡 Simple Way to Think About It

Waypoints are like:
> invisible signposts in the sky...  
> helping guide the airplane from one part of the route to the next.

## 🟢 Quick Fact

Many waypoint names are short five-letter codes used in flight planning and navigation systems.

A waypoint may be invisible to passengers -  
but it is one of the basic building blocks of how aircraft know where to go.
