Definition
An ATC instruction that cancels a previously issued speed adjustment and authorizes the pilot to return to a normal operating speed of the pilot's choosing. It does not cancel any other restriction, such as those associated with a published procedure (for example, speed limits in a Standard Terminal Arrival or below 10,000 feet MSL).
Plain English
Controller is telling you the speed they assigned earlier no longer applies — you can fly at whatever speed is normal for your aircraft and the situation, as long as other speed rules still in effect are respected.
Context Anchor
Heard on the radio after air traffic control has assigned a specific speed, such as during arrival, approach, departure, or traffic sequencing.
Why Pilots Care
Pilots must understand this clears only the controller-assigned speed, not regulatory or procedural speed limits. Accelerating through a published arrival speed restriction or the 250-knot limit below 10,000 feet because you heard 'resume normal speed' is a common and serious mistake.
Intuition Check
Do not assume “Resume Normal Speed” means “fly any speed you want.” It only cancels the specific speed change air traffic control gave you; other required speed limits may still apply.
Example Sentence 1
After the traffic ahead landed, the controller said, 'November One Two Three Alpha, resume normal speed,' and the pilot accelerated back to the aircraft's usual cruise descent speed.
Example Sentence 2
The controller canceled the speed reduction and instructed us to resume normal speed on the arrival.
