Definition
An instrument that continuously measures and records temperature values over time, typically producing a written or electronic trace that shows how temperature changed during a given period.
Plain English
A device that keeps an ongoing record of temperature, so you can look back later and see exactly how hot or cold it was at any point.
Context Anchor
Seen in aircraft systems, maintenance, and cargo operations when temperature history matters, such as checking for overheating or protecting temperature-sensitive cargo.
Why Pilots Care
A continuous temperature record can reveal trends — such as a slowly climbing cylinder head temperature or a cargo compartment that drifted out of range — that a single glance at a gauge would miss.
Intuition Check
Do not assume “recorder” means only a cockpit voice recorder or flight data recorder. Here, it means any device that logs temperature readings over time.
Example Sentence 1
The maintenance crew reviewed the temperature recorder trace to confirm the engine had not overheated during the previous flight.
Example Sentence 2
The temperature recorder logged a steady rise in oil temperature during the climb.
