Preflightcontroles

Preflightcontroles is a term used to describe the set of checks conducted before an aircraft is cleared for flight. The concept encompasses systematic reviews aimed at verifying airworthiness, operational readiness, and compliance with regulatory requirements. While most commonly associated with aviation and space operations, the idea also appears in other transport and production contexts where an early risk assessment is essential. The overarching aim is to identify and remedy faults before departure to enhance safety and reliability.

The scope of preflightcontroles typically includes exterior and interior readiness, flight planning, and documentation. Exterior checks examine the airframe, landing gear, control surfaces, hinges and linkages, engines or propulsion units, fuel and oil levels, hydraulic fluids, fuel leaks, and exterior lighting. Interior checks focus on cockpit instrumentation, flight management and navigation systems, autopilot and communications, cabin preparedness, emergency equipment, and weight and balance calculations. Also crucial are weather data, NOTAMs, air traffic clearances, and MEL—the minimum equipment list—ensuring the aircraft can operate legally and safely.

Procedures are usually defined by operator-specific checklists grounded in regulatory standards from authorities such as the FAA or EASA. Pilots and crew use these checklists to confirm system functionality, verify data integrity, and ensure required disconnections and protections are in place. Modern aircraft often employ electronic or integrated checklists and fault monitoring that highlight discrepancies for crew action.

In practice, preflightcontroles reflect a broader safety culture that prioritizes proactive fault detection, documentation accuracy, and disciplined execution to reduce in-flight risk.
