Flugtauglich

Flugtauglich is a German adjective that describes the suitability or fitness to undertake a flight. It combines Flug (flight) and tauglich (fit, suitable) and is used in both human and mechanical aviation contexts. In practice, it is often translated as airworthy or fit to fly.

For people, particularly passengers and aviation crew, flight fitness refers to medical fitness to fly. Aviation authorities may require a Flugtauglichkeitsuntersuchung, or a medical certificate issued by an aviation medical examiner, to confirm that a person meets health and fitness requirements for flight. Criteria typically cover vision and hearing, cardiovascular and respiratory health, mental state, and the absence of substances or conditions that could endanger flight safety. Temporary illnesses or medications can affect a person’s Flugtauglichkeit, and certain jurisdictions impose specific limits for pilots, cabin crew, or pregnant travelers.

For aircraft and equipment, Flugtauglich also denotes airworthiness. An aircraft must be maintained according to prescribed schedules, with all systems functioning properly and any defects addressed before flight. The status of Flugtauglichkeit is supported by certificates, inspections, and compliance with regulatory requirements. When an aircraft no longer meets safety standards, it loses its Flugtauglichkeit and is restricted from flying until deficiencies are corrected.

In practice, the term is widely used in German‑speaking aviation communities and regulatory contexts across countries such as Germany, Austria, and Switzerland. While exact criteria vary by jurisdiction, the core idea remains safety: only those individuals and machines deemed Flugtauglich are permitted to fly. The word is also used more informally to indicate general readiness for air travel.
