Definition
A diagram that uses standardized symbols and connecting lines to show the step-by-step decision and action sequence used to isolate a fault in an aircraft system. Each branch represents a yes/no answer to a test question, leading the technician toward the next check or the identified cause.
Plain English
A picture-style guide that walks you through troubleshooting one step at a time. At each step you answer a simple yes or no question, and the chart points you to what to check next.
Context Anchor
Seen in aircraft maintenance, troubleshooting, and system-description material, especially when a manual guides the user through checks in a set order.
Derivation
From 'logic' (orderly reasoning) and 'flowchart' (a chart showing how something flows from step to step). Together it means a chart that flows through a reasoning process.
Why Pilots Care
Helps mechanics and pilots follow a complete, error-free sequence when diagnosing faults in aircraft systems.
Analogy
It is like a simple map for a decision: if the answer is yes, go this way; if the answer is no, go another way.
Intuition Check
A logic flowchart is not a wiring diagram and does not show where parts are physically located. It shows the order of decisions and actions to follow.
Example Sentence 1
The mechanic followed the logic flowchart in the maintenance manual to track down the intermittent radio fault.
Example Sentence 2
Following the logic flowchart step by step prevented the technician from skipping a critical check in the hydraulic system.
