Definition
A reference location along the airplane's longitudinal axis, measured in inches from a fixed datum point, used to identify the position of items for weight and balance calculations.
Plain English
A numbered point along the length of the airplane that tells you exactly how far something sits from a chosen starting line. Each station is just an inch-mark used to locate seats, fuel, baggage, and equipment for weight and balance.
Context Anchor
Seen in weight-and-balance information, loading instructions, equipment lists, and aircraft maintenance records.
Derivation
From Latin 'statio,' meaning a standing place or fixed position. In aviation, a station is a fixed position along the airplane's body used as a measuring reference.
Why Pilots Care
Stations determine the moment arm for every weight item, directly affecting whether the center of gravity stays inside the approved envelope for safe flight.
Analogy
Think of the airplane like a ruler laid from front to back. A station is one mark on that ruler, measured from the chosen zero point.
Intuition Check
Do not read station here as a radio station, train station, or weather station. In weight and balance, station means a measured location on the airplane.
Example Sentence 1
The baggage compartment is located at station 142, which means it sits 142 inches aft of the datum.
Example Sentence 2
Baggage placed at station 120 produced a large aft moment that required ballast to correct.
