Definition
A descriptive style used in aircraft drawings and illustrations in which only one half of a symmetrical part or assembly is shown, typically split along its centerline. Because the unshown half is a mirror image of the shown half, drawing it would add no information.
Plain English
A drawing that shows only one side of a symmetrical part because the other side looks exactly the same.
Context Anchor
Seen in aircraft maintenance drawings, parts diagrams, and engineering drawings where a part is the same on both sides.
Why Pilots Care
Helps maintain proper glide path without instruments by using the runway's position in the view.
Intuition Check
Do not read “half view” as limited cockpit visibility or a partly missing drawing. In this context, it means the drawing intentionally shows only half of a matching, symmetrical object.
Example Sentence 1
The maintenance manual used a half view of the wing rib to save space, since both sides of the rib are identical.
Example Sentence 2
The instructor reminded me to hold half view all the way to the flare.
