Definition
A steady, unchanging rate of movement or change — for example, a constant rate of turn, climb, descent, or roll — held the same from start to finish without acceleration or hesitation.
Plain English
Doing something at the same speed the whole way through, not faster at one moment and slower at another.
Context Anchor
Seen in instrument flying when a pilot is controlling the aircraft by watching how the instruments change over time.
Derivation
From Latin uniformis, meaning 'having one form,' combined with rate (Latin rata, 'fixed amount'). Together: 'one consistent amount over time' — which is exactly what the pilot is asked to produce with the controls.
Why Pilots Care
A uniform rate lets the pilot's inner ear adapt gradually and reduces the chance of spatial disorientation when visual references are lost.
Grounding Statement
If the number or needle keeps moving at the same pace, the change is occurring at a uniform rate.
Intuition Check
Uniform does not mean correct or safe by itself. It means the change is steady; the pilot still has to make sure the steady rate is the one desired.
Example Sentence 1
The instructor told the student to roll out of the turn at a uniform rate rather than snapping the wings level.
Example Sentence 2
Climb at a uniform rate so the airspeed remains stable throughout the departure.
