Small Cockpit Device On All Passenger Planes

Sun Aug 04, 2019 10:33 pm

I may have asked this question long ago but I don't remember the answer. When I see pics or videos taken of the cockpit, on the bar between the captain and first officer's window, there is like a rod with three balls on it. Usually they are one black one in the middle and a white one on either side. It does not seem to move or do anything but sit there. What is it? I thought all aircraft have it but I looked through pics of 350 and 748 and 787 and could not find it. I found a good pic of one on this Dash 8

You bet I'm pumped!!! I just had a green tea!!!

Don't know the exact name of it, but I'm pretty sure it's a reference point of where the pilot's eyes should be.

It’s a sight target. When the pilots’ eyes are aligned to it, they are in the “proper” position.

When teaching taxi, I used to explain that when aligned to the target, all the sight lines and angles in the AMM and taxi manuals were valid.
When seconds count...the police are minutes away.
Unless it's expressly prohibited, it's allowed.

It is a visual reference point for the pilots when adjusting the seat height.

On Boeing airplanes they were called “seat alignment balls” which were standard equipment on the 707, 727, 737 and 747. With the coming of the 757 and 767 they started disappearing. The 737NG didn’t have them, nor the 747-400 except for a few customers (ANA was one). A Boeing production pilot who “squawked” the alignment of the balls on almost every airplane he flew got a supersized version with 3” balls to put on the hood of his car when he retired in the early 80’s.

The earlier Citstions (500, Citation I and II) had them, can’t say about the later models, the Bombardier jets have them.

On the 747 the same is done with the black crossed stripes on the left and right window bar

I would adjust my seat center them. Then, slide one notch back and one notch down. Whatever works.
