ELI5: Explain Like I'm 5

Primary flight display

Okay kiddo, let me explain to you what a primary flight display (PFD) is.

Imagine you want to go on a trip, but instead of riding a car or a bicycle, you want to fly a plane. Cool, right? But how do you make sure the plane goes where you want it to go and stays in the air? That's where the PFD comes in!

The PFD is like a big TV screen that's right in front of the pilot's seat in the cockpit of an airplane. It shows all sorts of important information that the pilot needs to fly the plane.

The PFD has many colors and lines that help the pilot understand what's happening with the plane. For example, there's a line that represents the horizon, which shows the pilot whether the plane is flying straight or not. If the line is tilted, the pilot knows the plane is going up or down, so they can adjust the plane's altitude to make sure it's flying level.

There are also other lines and numbers on the PFD that tell the pilot how fast the plane is going, how high it is, and which direction it's flying in. There are even little pictures that show how the airplane is tilting left, right, up or down.

All of this information is really important because it helps the pilot make sure the plane is flying safely and that everything is working properly. The PFD is like a map and a guide that helps the pilot navigate the skies and avoid any obstacles or dangers that might be in the way.

So, the PFD is like a super smart and useful TV screen that helps pilots understand what's going on with their airplanes, keep them flying level and on course, and make sure that everyone on board stays safe.
