Definition
A reference location along the length of the fuselage, measured in inches from a fixed datum point at or near the nose of the aircraft. Fuselage stations are used to identify the longitudinal position of structures, equipment, and load points for purposes of construction, maintenance, and weight-and-balance calculations.
Plain English
A number that tells you how far back along the body of the airplane a particular point is, measured in inches from a starting point near the nose.
Context Anchor
Seen in aircraft manuals, inspection instructions, repair information, equipment lists, and weight-and-balance data.
Derivation
Fuselage comes from the French fuselé, meaning 'spindle-shaped,' describing the long, tapered body of the aircraft. Station here means a fixed measured position along that length, like a milepost on a road.
Why Pilots Care
Accurate fuselage station references ensure proper center of gravity calculations, which are critical for safe flight handling and stability.
Analogy
Think of fuselage stations like house numbers along a street. The number does not describe the object there; it tells you where to find it along a measured line.
Intuition Check
Station does not mean an airport, radio station, or building here. It means a measured location on the airplane’s body.
Example Sentence 1
The cargo tie-down point is located at FS 215, meaning it sits 215 inches aft of the reference datum.
Example Sentence 2
Verify the cargo placement against the fuselage station limits in the weight and balance form.
