Definition
Time values, established through detailed engineering analysis of each task, that specify how long a given maintenance job should take when performed by a qualified technician using approved tools and procedures. These standards are used in aviation maintenance facilities to plan workloads, estimate labor costs, schedule aircraft downtime, and measure shop productivity.
Plain English
A set of pre-calculated 'how long should this job take' figures for maintenance tasks, worked out by studying each task carefully rather than just guessing.
Context Anchor
Seen in maintenance planning, shop scheduling, labor estimating, and discussions about how aircraft maintenance work is measured.
Derivation
Engineered' here means 'worked out methodically through study and analysis,' not 'designed by an engineer.' The phrase signals that the time figures are based on careful measurement of the actual steps in a task, rather than rough estimates.
Why Pilots Care
These standards ensure accurate predictions of takeoff distances, climb rates, and landing performance critical for safe operations.
Analogy
It is like a careful time estimate for a repair job: not a random guess, but a planned benchmark based on how the job should normally be done.
Intuition Check
Do not read engineered as meaning engine-related. Here it means carefully developed from work analysis, and performance means work output or time for a task—not aircraft speed or handling.
Example Sentence 1
The shop uses Engineered Performance Standards to estimate how many labor hours a 100-hour inspection should require.
Example Sentence 2
Maintenance records confirmed that the aircraft met all Engineered Performance Standards before the ferry flight.
