Definition
A number greater than zero, written with or without a plus sign (for example, 5 or +5). Positive numbers represent quantities above a chosen reference point, such as zero on a scale or gauge.
Plain English
Any number bigger than zero. It tells you there is something there, or that a value is above the starting point.
Context Anchor
Seen in aviation maintenance math, electrical readings, temperature corrections, tolerances, and weight-and-balance calculations.
Derivation
From Latin positivus, meaning 'placed' or 'set down firmly.' A positive number is one that is firmly above zero, as opposed to a negative number which sits below it.
Why Pilots Care
Maintenance work involves constant measurement and calculation. Knowing whether a value is positive or negative changes the meaning of a reading — a torque value, a clearance, or a temperature differential. Confusing the sign can lead to incorrect calculations and incorrect maintenance actions.
Intuition Check
Positive does not mean “good” here. It means “greater than zero” or “on the plus side of zero.”
Example Sentence 1
When adding 7 and 3, the result is the positive number 10.
Example Sentence 2
During the weight and balance check, all added equipment contributed a positive number to the total moment.
